Degu case method: 50 questions

You keep two 3-year-old degus. One September morning you notice the water bottle has been emptying almost twice as fast over the past week, and the cage bedding is always wet with urine. Looking closely at one degu's eyes, the back of the pupil is faintly clouded white. Since last month your child has been giving diced apple as a daily treat "because they love it." The degu seems a little thinner.

Which is the most appropriate action for the owner?

1. Buy over-the-counter eye drops, halve the apple, and watch
2. Stop apple and all sugary treats completely, collect urine, and see a vet within a few days
3. The problem is overdrinking, so remove the bottle and offer water only twice a day
4. Cataracts are just aging and need no treatment, so carry on as before

AnswerB. Stop apple and all sugary treats completely, collect urine, and see a vet within a few days

ExplanationExcessive drinking and urination, clouded eyes, and weight loss are the classic early signs of degu diabetes and the cataracts that accompany it. Degus metabolize sugar poorly, and sweet treats like fruit can trigger the disease within weeks. The correct answer is to stop all sugar immediately, collect urine, and see a vet within a few days; the vet will assess urine glucose and weight and advise on diet. Store-bought eye drops or merely cutting back leave the cause in place and the disease progresses. Restricting water causes dehydration and kidney damage and is extremely dangerous; thirst is a sign of the disease, not its cause. Cataracts at age 3 should be treated as disease, not aging.

IssuesThe owner applied the "fruit is healthy" assumption from other small animals to a degu, and the whole family had not shared the no-sugar rule. Water intake and weight were not recorded in numbers, so the change was noticed late.

ImprovementAgree as a family that degus never get fruit or sweet food, and post a note on the cage. Limit treats to a tiny amount of dried wild greens. Make weekly weigh-ins and checks of the water bottle markings a habit, and see a vet if intake jumps.

You keep a single 4-year-old degu. On Sunday evening you notice the fur under the chin and on both front paws is wet and matted with drool. It takes hay into its mouth but drops it right away, and avoids the hard pellets. For about a month the hay has been going down slowly, and you had been giving extra pellets instead. The mouth also seems not to close fully.

What is the most appropriate response in this situation?

1. The teeth seem overgrown, so trim the incisors with household nail clippers
2. If it won't eat hay, there's no choice: increase pellets further to keep weight on
3. Avoid hard food, feed softened pellets, and see a vet that can do dental work within a few days
4. Assume the drooling is from heat, cool the room, and watch for a week

AnswerC. Avoid hard food, feed softened pellets, and see a vet that can do dental work within a few days

ExplanationDrooling, avoiding hard food, a mouth that will not close, and reduced hay intake are classic signs of malocclusion. Degu teeth grow for life and are worn down by grinding hay. On a pellet-heavy diet the cheek teeth are not worn, overgrow, and injure the cheeks and tongue, causing drool. The correct answer is to maintain nutrition with softened pellets while seeing a vet within a few days that can examine the cheek teeth and perform dental work. Cutting incisors with nail clippers splits the teeth and damages the roots, and does nothing for the cheek teeth. More pellets worsens the root cause. Waiting a week leads from poor appetite to weakness and gut stasis. If it stops eating, switch to a same-day visit.

IssuesWhen hay intake dropped, the owner interpreted it as a change in taste and compensated with pellets, masking the dental problem. With a single degu there was no comparison, so the change in eating was not taken seriously.

ImprovementObserve how and how much hay is eaten every day, and suspect the teeth first when it drops. Check incisor length and color (normal is orange) once a week. Limit pellets to about 5% of body weight and let hay and chew sticks wear the teeth. Find a vet that does dental work in advance.

A 2-year-old degu. On Saturday morning it ignores the hay it normally pounces on and sits hunched in a corner of the nest box. The droppings in the tray are less than half their usual size and few in number. You recall stopping it from chewing the sofa cover during free-roam time the night before. When you try to touch its belly, it resists and runs away. By evening it still has not eaten.

Which is the most appropriate action for the owner to take at this point in the evening?

1. Place hay and water nearby, keep it warm, suspect a blockage, and see a vet the same day
2. Give dried banana to stimulate appetite and watch until tomorrow morning
3. Massage the belly firmly to push out droppings; if some come out, stop worrying
4. Dissolve a tiny pinch of human probiotic medicine in water and give it

AnswerA. Place hay and water nearby, keep it warm, suspect a blockage, and see a vet the same day

ExplanationA degu that has not eaten for over half a day develops gut stasis, which is life-threatening. Small, scant droppings, sitting hunched and still, and resisting belly contact, together with the cloth-chewing the previous night, strongly suggest an intestinal blockage from swallowed fabric. The correct answer is to put hay and water within reach, keep it warm, and see a vet the same day. Sweet dried fruit causes diabetes and does nothing about why it is not eating. Firm abdominal massage can damage a blocked intestine. Human medicine is wrong in both dose and ingredients and is dangerous. Once it has gone half a day without food, "wait and see" is not an option.

IssuesFabric items were left out during free-roam time and the amount chewed was not checked. The abnormality was noticed in the morning but the vet visit was put off until evening, crossing the dangerous half-day threshold.

ImprovementRemove cloth, cotton, and plastic before free-roam time and limit what can be chewed. Check the size and number of droppings in the tray every morning, and decide in advance that a drop means a same-day vet visit. Look up animal hospitals open on weekends and post the contact details on the cage.

At 3 p.m. in late July you come home to find the living-room air conditioner has switched off on its timer and the room is 32°C. In the cage your 1-year-old degu is lying flat on the floor, its chest heaving. Its ears are bright red, drool is dripping from its mouth, and when you call its name it barely moves its head.

Which is the most appropriate first action?

1. Submerge the body in cold water to bring the temperature down fast, then see a vet once it settles
2. Wrap the body tightly in a wet towel and point a fan directly at it
3. Move it to a cool room, place a towel-wrapped ice pack nearby, and go to the vet immediately
4. To prevent dehydration, open the mouth, squirt in water with a dropper, and let it rest

AnswerC. Move it to a cool room, place a towel-wrapped ice pack nearby, and go to the vet immediately

ExplanationLethargy, rapid breathing, red ears, drooling, and lying flat are the classic picture of heatstroke in a degu, an emergency that can kill within hours if ignored. The correct answer is to move it to a cool room, place an ice pack wrapped in a towel near the body to cool it gradually, and go to the vet right away. Submerging in cold water causes shock from the sudden temperature drop and wets the coat, disrupting temperature regulation. Wrapping in a wet towel is unsuitable for a degu from an arid habitat; it overcools and causes dermatitis. Pouring water into a semiconscious animal leads to aspiration pneumonia. Keep cooling during transport and phone the clinic ahead to describe the situation.

IssuesThe owner set the air conditioner on a timer and did not anticipate the room heating up while out. They knew 28°C and above is dangerous for degus but had not turned that knowledge into a plan for when away from home.

ImprovementRun the air conditioner continuously in summer and never switch it off when going out. Put a thermometer in the cage and add a thermo-hygrometer that can be checked by phone. Keep a marble cooling plate in place at all times, and prepare an evacuation site and frozen water bottles for power outages.

In the June rainy season you find a circular bald patch about 1 cm across on the back of one of your three degus (age 2). The skin is slightly red with flaky dandruff. It scratches with its hind leg many times a day. The sand in the bath container has been damp for about two weeks, and bedding changes had slipped to about once a month. The other two show no problems so far.

What is the most appropriate response?

1. Apply a thin layer of human anti-itch ointment and watch whether the patch spreads
2. Dust baths will heal it naturally, so increase the number of baths and wait a month
3. Separate the affected degu into its own cage, replace the sand and bedding with fresh dry material, and see a vet within a few days
4. Wash all three in lukewarm water to clean the skin and dry them with a hair dryer

AnswerC. Separate the affected degu into its own cage, replace the sand and bedding with fresh dry material, and see a vet within a few days

ExplanationA circular bald patch with itching and dandruff is typical of dermatitis, especially ringworm (dermatophytosis), for which damp sand and dirty bedding are a breeding ground. Ringworm spreads to cage mates and to people, so the correct answer is to isolate the affected animal, replace the sand and bedding with fresh dry material, and within a few days see a vet that can test the skin. Human ointment is toxic if licked, does not work on fungi, and delays diagnosis. Bathing in damp sand actually spreads the fungus. Water baths are strictly forbidden for degus; they strip the coat's oils and cause hypothermia and skin problems. Always wash hands after handling, and switch to a same-day visit if it spreads or appears in other animals.

IssuesThe owner let sand care and bedding changes slide during the humid rainy season. They did not realize how extremely sensitive degus are to damp, or that a circular bald patch can spread to people.

ImprovementCheck the bathing sand daily and replace it if damp; keep humidity at 40–60% with a dehumidifier. Return to spot-cleaning bedding daily and a full change weekly. Check the skin once a week, and if a bald patch appears, isolate the animal and wash hands thoroughly.

You keep four degus including a 6-year-old male. One January morning, the 6-year-old, which usually sleeps piled up with the others, is crouched alone in a corner outside the nest box and does not call at feeding time. When you lift it, it feels light, and its coat is standing up and dull. It nibbles a little hay but soon stops. The room is 22°C and the other three are fine.

Which is the most appropriate judgment of this situation?

1. It is natural aging, so just provide a quiet environment and watch
2. The others pushed it out, so move the other three to another room to prevent bullying
3. It has become nocturnal, so darken the room and let it sleep during the day
4. Leaving the group and going silent is a serious sign: keep it warm and see a vet the same day

AnswerD. Leaving the group and going silent is a serious sign: keep it warm and see a vet the same day

ExplanationDegus live in groups and communicate by calling. One that withdraws from its companions, stops calling, has a raised coat, and loses weight is showing its instinct to hide illness, meaning the disease is already well advanced. In older animals the underlying cause is often a tumor, kidney failure, dental disease, or diabetes. The correct answer is to keep it warm, see a vet the same day, and have the weight loss investigated. Dismissing it as aging means missing a treatable illness. Moving the other three breaks up the group's bonds and stresses the sick animal too. Degus are diurnal and never become nocturnal, so darkening the room is pointless.

IssuesThe assumption that "it's just old age" made the owner hesitate to see a vet. In a multi-degu household the weight and food intake of each animal were not tracked, so the loss was noticed only after it was thin.

ImprovementWeigh elderly degus twice a month and have a check-up every six months. In a group, identify each animal and check daily for changes in eating and calling. Share with the family that withdrawing from the group or going silent means a same-day vet visit.

During free-roam time your 1-year-old degu dashed behind the TV stand. You reached out in a panic and grabbed the tip of its tail; the skin slid off in an instant, leaving a tube of fur in your hand. The degu returned to the cage, but from mid-tail to the tip there is no skin, bone and red tissue are visible, and a little blood is oozing. It keeps licking the tail.

What is the most appropriate response?

1. Slide the skin back over the tail, tape it in place, and wait for it to reattach
2. Do not touch the exposed part, cover it lightly with clean gauze, and see a vet the same day
3. The tip will fall off on its own, so pour on plenty of antiseptic and let nature take its course
4. Crush a small amount of human painkiller for the pain and see a vet the next day

AnswerB. Do not touch the exposed part, cover it lightly with clean gauze, and see a vet the same day

ExplanationA degu's tail skin is built to slip off easily so it can escape predators, and once it comes off it never goes back. The exposed bone and tissue dry out, die, and become a source of infection, so the correct answer is to leave the exposed part untouched, cover it lightly with clean gauze, and see a vet the same day for treatment such as removal of the dead portion. Replacing the skin does not regenerate it, and tape constricts the tissue and makes things worse. Waiting for it to fall off lets the necrosis advance and the infection can spread through the body. Antiseptic irritates the tissue. Human painkillers easily reach toxic doses in a tiny degu and must never be given without veterinary advice.

IssuesThe owner did not know the basic rule of never grabbing the tail of an escaping degu. The gaps around furniture were not blocked before free-roam time, and no catching technique had been practiced.

ImprovementTeach the whole family to pick up a degu by cupping the whole body in both hands and never to hold the tail. Block the gaps around furniture in the free-roam room, and have a way to lure it back with the sand bath or nest box if it escapes. Make it a habit not to chase in a panic.

You keep two degus in an 80 cm tall three-level cage. At 9 p.m., after a thud, your 1.5-year-old degu is on the bottom floor holding its left hind leg up and not moving; when it tries to move, it drags the leg. Just above the ankle looks swollen. The other degu comes over and nudges it, but it squeaks in protest.

Which is the most appropriate first action?

1. Feel the leg to check for a fracture, and if broken, splint it with a chopstick
2. Separate it from its cage mate, place it in a small box to rest, do not handle it, and see a vet the same day
3. It can still walk, so it is not broken; see a vet on your next day off next week
4. Remove the wheel to encourage rest and leave it in the cage with its cage mate

AnswerB. Separate it from its cage mate, place it in a small box to rest, do not handle it, and see a vet the same day

ExplanationFalls in multi-level cages are a leading cause of fractures, and holding up a leg, dragging it, and swelling are signs of a fracture or dislocation. The correct answer is to separate it from its cage mate, place it in a small box so it cannot move around, and without handling it see a vet the same day (an emergency clinic if at night). Probing the leg can shift bone fragments and damage nerves and vessels, and a splint on a tiny degu does not immobilize anything and only adds pain. Many fractured animals can still walk, and if left untreated the bone heals deformed or dies. Left with its cage mate it may be trampled or try to climb and worsen. Transport in a dark carrier lined with a towel, without jolting.

IssuesThe cage levels were high with no landing spots or intermediate steps. The owner did not know which hospital was open at night, which delayed the decision.

ImprovementKeep level changes low and add wooden steps or shelves within reach to break up the drop. List emergency (after-hours) animal hospitals and their contact details in advance. Keep a small box and small carrier on hand as a rest kit for injuries.

You keep a 1-year-old degu in a cage with a wire floor because it is easy to clean. In the evening you rush over at the sound of shrieking and find its right front leg has dropped through a gap in the wire up to the shoulder, wedged deeper the more it struggles. The visible part of the leg is starting to turn red and swell. The degu is panicking and keeps twisting its body.

Which is the most appropriate first action?

1. Grab the leg and yank it straight up so it is over quickly, even if it hurts
2. Struggling is dangerous, so hold the body down and wait about 15 minutes for it to calm
3. Support the body with one hand to stop it moving, then slowly bend the wire apart with pliers to free the leg
4. Rub olive oil on the leg to make it slippery and wait for it to pull free on its own

AnswerC. Support the body with one hand to stop it moving, then slowly bend the wire apart with pliers to free the leg

ExplanationWhen a leg is trapped, pulling it out while the animal struggles causes fractures, skin tearing, and dislocated joints. The correct answer is to gently support the body so it cannot twist further and slowly open the wire with pliers to release the leg. Afterward, if there is swelling, bleeding, or it will not put weight on the leg, see a vet the same day. Forcing the leg out is the most common mistake, and even when the leg comes free it is often fractured. Just holding it down and waiting cuts off blood flow and the tissue dies. Oil does little, causes diarrhea when licked, and soils the coat. Damage increases the longer the leg is trapped, so act calmly but quickly.

IssuesThe owner prioritized easy cleaning and used a wire floor unsuited to degu feet. The structural hazards of the cage had not been checked, and no tools were at hand.

ImprovementRemove the wire floor and switch to a solid floor with slats, wood chips, or paper bedding. Choose a wheel with a solid side and no gaps. Check cage gaps with a finger and keep pliers and a towel nearby. After a trapping, watch how the leg is used until the next day even if there is no swelling.

You put a newly acquired 4-month-old male into the same cage as your 2-year-old male on the same day. After 30 minutes fierce chasing began, and the newcomer has a bite mark on its back with blood oozing. The resident has its fur raised and is chattering its teeth, while the newcomer trembles in a corner of the cage. There is only one food dish.

What is the most appropriate response?

1. It is a rite of passage until rank is settled, so leave them together overnight and watch
2. Separate them into different cages immediately, press the wound with gauze, and see a vet if bleeding continues, it swells, or the animal is listless
3. Bathe the two together so they smell the same and get along
4. Scold the resident and shut it in another room, leaving only the newcomer in the original cage

AnswerB. Separate them into different cages immediately, press the wound with gauze, and see a vet if bleeding continues, it swells, or the animal is listless

ExplanationDegus are social, but put straight into the same cage they fight fiercely over territory and can inflict fatal wounds. The correct answer is to separate them at once, press the wound with clean gauze for a few minutes to stop the bleeding, and see a vet the same day if bleeding will not stop, it swells, or the animal is listless or not eating. Even small bite wounds readily form abscesses under the skin. Leaving them together as a "rite of passage" can lead to serious injury or death overnight. Water baths are strictly forbidden for degus; they strip the skin oils and make the animal ill. Punishing the resident achieves nothing, and the stress of a changed environment worsens the relationship. Introduce by placing separate cages side by side for several weeks and providing multiple food dishes before proceeding carefully.

IssuesBecause "they live in groups," the owner housed them together on day one with no quarantine or acclimation period. A single food dish caused competition over resources. The owner also could not judge when to stop the fight.

ImprovementKeep the newcomer in a separate cage for about two weeks for a health check and quarantine, then place the cages side by side to get used to each other's scent. Make first meetings short, supervised, and in a neutral area. Provide at least one dish, water bottle, and nest box per animal, and decide in advance that pairs that keep fighting will be housed separately.

Your 3-year-old degu's nails were long, so you trimmed them at home for the first time with human nail clippers. You cut one too short and blood is dripping from the tip. The degu struggled free of your hands, leaving spots of blood on the cage bedding. It shows no sign of stopping, and the bleeding increases every time it digs in the bedding.

What is the most appropriate response?

1. Press the nail tip gently with clean gauze for a few minutes to stop the bleeding; see a vet if it does not stop
2. Hold the foot under running water to wash away the blood until it looks clean
3. It will stop on its own, so leave it and do not change the bedding until tomorrow
4. Pour on plenty of human antiseptic, wrap the foot in tissue, and secure it with a rubber band

AnswerA. Press the nail tip gently with clean gauze for a few minutes to stop the bleeding; see a vet if it does not stop

ExplanationA degu's nails contain a blood vessel and bleed if cut too deep. The correct answer is to cup the body in both hands to restrain it and press the nail tip gently with clean gauze for a few minutes to stop the bleeding. A small-animal styptic powder can be used as well. If it has not stopped after 5–10 minutes, the degu becomes limp, or it drags the foot, see a vet the same day. Running water washes away the clot, prevents clotting, and chills the animal. Leaving it risks infection from soiled bedding, and in a degu this small even minor blood loss matters. A rubber band cuts off circulation and causes tissue death, and antiseptic stings, causing struggling and renewed bleeding. Replace the bedding once the bleeding has stopped.

IssuesThe owner cut in one go with human clippers without locating the blood vessel. They had not practiced restraint and had no styptic supplies on hand. Letting go when it struggled created a secondary risk of the wound being contaminated by bedding.

ImprovementUse small-animal nail clippers and cut only the tip, short of the visible blood vessel. Do one nail at a time over several days, and if it struggles, have the vet trim instead. Keep gauze and small-animal styptic powder next to the cage.

During evening free-roam time your 8-month-old degu ran up to your feet as you headed to the kitchen. Not noticing, you took a step and heard a squeak under your heel. The degu stays where it is, breathing fast with its mouth slightly open. When you try to pick it up, it stiffens and seems in pain. No bleeding is visible.

Which is the most appropriate first action?

1. Feel the whole body to find where it is broken and cool the painful spot
2. Without handling the body, gently place it in a small dark box, keep it warm, and see a vet right now
3. There is no bleeding so it is fine; return it to the cage and watch until tomorrow
4. Hold and stroke it continuously to ease the shock, then see a vet once it has calmed

AnswerB. Without handling the body, gently place it in a small dark box, keep it warm, and see a vet right now

ExplanationWhen a person steps on a degu weighing around 200 g, rib fractures, internal organ damage, and bleeding in the lungs are likely even with no visible wound. Rapid open-mouth breathing is a sign of chest injury or severe pain. The correct answer is to avoid handling the body, gently place it in a small towel-lined box, keep it dark and warm, and see a vet right now; treat it as an emergency if it barely responds or breathing is labored. Feeling the body all over moves bone fragments and worsens internal bleeding. The absence of bleeding is no proof of safety; internal injuries can deteriorate suddenly hours later. Holding and stroking compresses the chest and further hinders breathing.

IssuesThe owner knew degus run to people's feet, yet walked during free-roam time without looking down. They also lacked the knowledge that severity cannot be judged by whether or not there is bleeding.

ImprovementAlways check your feet before walking during free-roam time and get into the habit of shuffling. Confine the roaming area with a playpen and limit it to times when you are sitting down. Agree as a family that stepping on or pinching a degu means an immediate vet visit even without a visible injury.

During free-roam time you slid a door shut to go to another room and caught your 2-year-old degu, which had been following behind, across the hips and hind legs. You opened the door at once and it walked a little on its own, but the hind legs moved awkwardly, and after a while it sank down onto its hindquarters. A little urine is leaking.

What is the most appropriate response?

1. It walked on its own so it is fine; return it to the cage as usual and observe
2. Gently massage the hips to improve circulation and watch until morning
3. Suspect a fracture or spinal injury, rest it in a small box, and see a vet right now
4. Cut a small piece of human pain-relief patch and stick it on the hips

AnswerC. Suspect a fracture or spinal injury, rest it in a small box, and see a vet right now

ExplanationBeing caught in a door or sliding door readily causes pelvic fractures and spinal injury, and awkward hind legs, sinking down, and urine leakage are findings that strongly suggest nerve damage. The correct answer is to place it in a small box so it cannot move and see a vet right now; the chance of recovery from nerve damage falls as time passes. Even if it walks immediately afterward, it is not unusual for swelling and bleeding to progress and leave it unable to move hours later. Massaging the hips can shift bone fragments or the damaged spine and make paralysis permanent. The ingredients in human patches are toxic to small animals and cause poisoning if licked. The manual also says to suspect a fracture and see a vet after a pinching injury.

IssuesThe owner closed the door without checking the degu's position, ignoring its habit of following people around. They also tended to misread "it walked" as proof of recovery.

ImprovementDo not open or close doors and sliding doors during free-roam time, or always look for the degu first. Limit free-roam to a single room to reduce comings and goings. Decide that a pinched degu goes to the vet even if it can walk, and keep the emergency (after-hours) clinic's number handy.

You come home to find the wire cage door chewed, the latch off, and your 2-year-old degu gone. The living room connects to the hallway and kitchen; the front door is closed but the windows have only screens. There is no cat in the house, but electrical cords and houseplants are on the floor. It is evening and getting dark.

Which is the most appropriate first action?

1. Move all the furniture, call its name loudly, and grab it by the tail when found
2. It will come back on its own, so leave the cage open, go out, and check in the morning
3. Close the windows and doors, keep quiet, and put the sand bath and nest box on the floor to lure it out
4. Suck under the furniture with a vacuum to startle it and catch it as it bolts out

AnswerC. Close the windows and doors, keep quiet, and put the sand bath and nest box on the floor to lure it out

ExplanationA frightened degu hides in narrow gaps and will not come out. The correct answer is first to close the windows and doors to confine it to one room, keep quiet, and set its beloved sand bath, familiar nest box, and hay on the floor so it comes out on its own. When it does, catch it by cupping the body in both hands and never grab the tail. Shouting, moving furniture, or vacuuming cause panic, driving it deeper into furniture and causing tail slip or falls. Going out and leaving it risks electrocution from chewed cords, poisoning from houseplants, escape through the screens, and cold at night. Watch your feet constantly while searching.

IssuesThe owner did not anticipate the latch being chewed and had added no extra fastening. Electrical cords, houseplants, and other hazards were left out in the room, making an escape far more dangerous.

ImprovementDouble-secure the door with a carabiner or clip and inspect chewed spots daily. Cover electrical cords and move houseplants out of reach. Share the escape procedure (seal the room, stay quiet, lure with the sand bath) with the family.

During free-roam time your 1-year-old degu was chewing an extension cord behind the sofa. With a loud crack the degu jumped, collapsed on the floor, and is twitching in small seizures. The area around its mouth looks blackened, and the cord's insulation is torn with the copper wire exposed. The cord is still plugged into the outlet.

Which is the most appropriate first action?

1. Immediately pick the degu up away from the cord and check inside its mouth
2. First unplug the cord to cut the power, then keep the degu warm and see a vet right now
3. Wait for the seizure to stop on its own, then return it to the cage and watch
4. Put water in its mouth and hold ice to its lips to cool the burn

AnswerB. First unplug the cord to cut the power, then keep the degu warm and see a vet right now

ExplanationIn an electrical accident, touching an animal still in contact with a live wire electrocutes the rescuer too. The correct answer is first to unplug the cord to cut the power, then wrap the degu in a towel to keep it warm and see a vet right now. Beyond mouth burns, electric shock can cause pulmonary edema and breathing difficulty hours later, so see a vet even if the seizure stops. Picking it up while the current is live causes a second casualty. Merely watching the seizure delays detection of respiratory arrest or pulmonary edema. Putting water or ice in the mouth of a semiconscious animal causes aspiration or hypothermia. Before the visit, clear any foreign matter from the mouth with a cotton swab and note the breathing rate to tell the vet.

IssuesThe owner allowed free-roam time with a live, unprotected cord within reach. They did not stop the chewing when it started and underestimated the danger of electric shock.

ImprovementCover cords in the free-roam room or unplug any not in use. Provide plenty of chew sticks to satisfy the urge to gnaw. Go over the electric-shock procedure (cut the power, do not touch, see a vet) with the family.

During free-roam time the changing-room door was open; your 1.5-year-old degu got into the bathroom and fell into the tub, which still held leftover bathwater. You found it a few minutes later and lifted it out: soaked through, limp, breathing weak and irregular, water coming from its nose. Its body is cold, and it only half-opens its eyes when you call.

Which is the most appropriate first action?

1. Hold it upside down by the tail and shake it to get the water out of its lungs
2. Blow hot air from a hair dryer over the whole body to dry it quickly, then lay it down
3. Lower the head to drain water from the mouth, blot dry with a towel, and see a vet right now while keeping it warm
4. It drank too much water, so leave it somewhere warm for a while to pass the fluid and watch

AnswerC. Lower the head to drain water from the mouth, blot dry with a towel, and see a vet right now while keeping it warm

ExplanationDegus are arid-habitat animals for which water baths are forbidden; when wet they lose body heat rapidly, and inhaled water causes pneumonia or pulmonary edema. The correct answer is first to hold the head lower than the body to drain water and debris from the mouth, blot it gently dry with a towel, and see a vet right now while keeping it warm with a wrapped hand warmer. If breathing is shallow, press the chest lightly with one finger during transport. Holding it by the tail and shaking causes tail slip and spinal injury and jars the internal organs. Hot air from a dryer risks burns and overheating, and just drying it and laying it down misses the lung damage. After near-drowning, an animal that seems to recover can develop breathing difficulty hours later, so always see a vet.

IssuesThe changing-room and bathroom doors were open during free-roam time, putting wet areas within the degu's range. Bathwater had been left in the tub, and the owner had not considered the risk of the degu falling into water.

ImprovementLimit free-roam to one room with the door closed, completely cutting off wet areas. Drain or cover leftover bathwater. Do not leave basins, buckets, tanks, or any water container on the floor. Prepare an emergency warming kit and carrier.

On Sunday at midday your elementary-school child reports, "It ate them happily!" On asking, they gave your 2-year-old degu three grapes with the skin on, and it ate them all. The degu is running around energetically for now, but the household had never taught the child the no-sugar rule.

Which is the most appropriate response for the owner?

1. It seems fine, so decide that small amounts are acceptable as rewards from now on
2. Force it to vomit by putting a finger in its mouth and striking its back hard
3. Stop all sugar from now on, record water intake, urine, and appetite for several days, and see a vet if anything changes
4. Withhold hay and water overnight to bring the blood sugar down

AnswerC. Stop all sugar from now on, record water intake, urine, and appetite for several days, and see a vet if anything changes

ExplanationGrapes are extremely high in sugar and strictly forbidden for degus. A single serving is rarely immediately life-threatening, but it can cause diarrhea, and repeated feeding leads directly to diabetes and cataracts. The correct answer is to stop all sugar from now on and record water intake, urine, droppings, and appetite for several days, seeing a vet if excessive drinking and urination, soft stool, or reduced appetite appear. Continuing with "just a little" is the fastest road to diabetes. Rodents are physically unable to vomit, so trying to induce vomiting only causes choking or mouth injury. Fasting shuts down the degu's gut, causing another serious illness, and does nothing to control blood sugar.

IssuesThe no-sugar rule for degus had not been shared with the child, so someone in the household could give dangerous food. Grapes were kept where the child could take them freely.

ImprovementExplain a picture-based "safe foods" list and "never" list to the whole family and post it on the cage. Keep treats to dried wild greens only, stored in a designated container. Let the child feed the degu only with an adult present.

During evening free-roam time your 1-year-old degu was chewing something under the table: a piece of chocolate bar dropped by a guest. By the time you took it away, a thumbnail-sized amount was gone. Thirty minutes later the degu is restlessly racing around the cage, breathing fast, with its body trembling slightly. It is 10 p.m.

What is the most appropriate response?

1. Give milk to dilute the poison and watch in the cage until morning
2. Phone the emergency (after-hours) animal hospital, report the amount and time eaten, and go in right away as instructed
3. It is just excited, so darken the room to calm it and see a vet tomorrow
4. Give salt water to make it vomit; once it vomits, there is nothing to worry about

AnswerB. Phone the emergency (after-hours) animal hospital, report the amount and time eaten, and go in right away as instructed

ExplanationThe theobromine and caffeine in chocolate reach toxic levels in a degu of around 200 g even in tiny amounts, causing agitation, tremors, rapid heart rate, seizures, and death. The correct answer is to phone the emergency (after-hours) animal hospital, report the amount, time, body weight, and symptoms, follow instructions, and go in right away; once symptoms have appeared, waiting is not an option. Milk does not dilute the toxin, and rodents get diarrhea from lactose. Degus cannot vomit, so salt water only adds salt poisoning and is extremely dangerous. Waiting in the dark until tomorrow allows seizures and arrhythmias to progress. Bring the wrapper if available and tell the vet the type of chocolate; it helps treatment.

IssuesThe owner allowed free-roam time on a day with guests without checking for dropped food. They did not know that degus cannot vomit or that the toxic dose of chocolate is tiny. The emergency clinic's number had not been checked either.

ImprovementInspect the floor at eye level on hands and knees before free-roam time, and skip it when guests are over. Share a list of dangerous foods (chocolate, onion family, raw potato, etc.) with the family. Save the emergency clinic's number and the degu's weight on your phone.

It is the third day since you put a fleece blanket in the sleeping area for winter warmth. In the morning a fist-sized corner has been chewed off and is missing, with fine fibers scattered on the floor. Your 2-year-old degu is eating hay, but the number of droppings is down to about two-thirds of normal. You cannot tell whether the belly is bloated.

What is the most appropriate response?

1. Remove the fleece at once, count the number and size of droppings, and see a vet the same day if they keep decreasing or appetite drops
2. Give oil to pass the fibers and keep it exercising until it produces droppings
3. It is still eating so there is no problem; the fleece is warm, so leave it in
4. Dissolve a tiny pinch of human laxative in water and give it for the constipation

AnswerA. Remove the fleece at once, count the number and size of droppings, and see a vet the same day if they keep decreasing or appetite drops

ExplanationDegus chew and swallow cloth and cotton, and the fibers block the intestine. Fewer droppings even while still eating is an early sign of impaired passage, so the correct answer is to remove the fleece immediately, provide plenty of hay and water, count the number and size of droppings, and see a vet the same day if they keep decreasing or shrinking, appetite falls, or it sits hunched and still. With droppings already reduced, an early call to the vet is advisable now. Oil or forced exercise damages a blocked intestine. "It's eating so it's fine" delays the decision, and a complete blockage requires surgery. Human laxatives are wrongly dosed and cause intestinal rupture if there is a blockage.

IssuesThe owner put in a blanket used for other small animals for warmth, unaware of the degu's habit of eating it. They noticed the change in droppings but tended to be reassured because it was still eating.

ImprovementProvide warmth with a wooden or ceramic nest box and a thick layer of hay, or a heater outside the cage, never with cloth. Never put cloth, cotton, or plastic in the cage. Make a morning droppings check routine and decide that a decrease means a same-day vet visit.

At noon in August a lightning strike causes a power outage and the air conditioner stops. There is no word on when power will return; the room reached 29°C in 30 minutes and is still rising. Your two degus (ages 1 and 3) are lying on the marble plate, breathing a little fast. You have ice packs and bottled water in the refrigerator, a car, and your parents' house in the next town has power.

Which is the most appropriate first action?

1. Mist both degus with a spray bottle and keep fanning them with a hand fan
2. Place towel-wrapped ice packs from the refrigerator in the cage and prepare to evacuate somewhere cool
3. Put a dish of ice water in the cage so they can soak their bodies
4. Degus tolerate heat well, so leave them until it cools down in the evening

AnswerB. Place towel-wrapped ice packs from the refrigerator in the cage and prepare to evacuate somewhere cool

ExplanationDegus are at risk of heatstroke at 28°C and above, and a rising room temperature during an outage is a direct threat to life. The correct answer is to wrap ice packs or frozen water bottles from the refrigerator in towels and place them in the cage as a cooling source without direct contact, and if power does not return, prepare to evacuate to a cool place with electricity such as your parents' house. For the move, put ice packs in the carrier and cool the car first. Misting with water gives arid-habitat degus dermatitis and raises humidity, making things worse. A dish of ice water risks drowning and a sudden drop in body temperature. Degus are heat-sensitive; leaving them until evening leads to heatstroke with lethargy and drooling.

IssuesThe owner had not decided in advance on cooling methods and an evacuation site for a summer outage, so decisions took time. They had the habit of checking the thermometer but no action plan for when it rose.

ImprovementKeep frozen water bottles and ice packs in the freezer at all times, and post a written outage cooling procedure on the cage. Prepare an evacuation site (relatives' house, car) and a travel carrier, plus a small fan that runs on a power bank. Use a battery-powered thermo-hygrometer.

At 2 a.m. in January heavy snow causes a power outage, stopping the heater and air conditioner. The room has dropped to 8°C, and your two degus (ages 4 and 5) are huddled together in the nest box, sluggish; they respond when you call but will not come out. In the house you have disposable hand warmers, blankets, cardboard boxes, and a hot-water bottle.

What is the most appropriate response?

1. Cover the whole cage with blankets and cardboard and place towel-wrapped hand warmers against the outside of the nest box
2. Put the hand warmers straight into the nest box to warm their bodies as fast as possible
3. Place the degus directly on a hot-water bottle filled with hot water
4. They are only sluggish from the cold, so do nothing and wait for the power to return in the morning

AnswerA. Cover the whole cage with blankets and cardboard and place towel-wrapped hand warmers against the outside of the nest box

ExplanationTemperatures below 10°C are forbidden for degus; at 8°C hypothermia sets in, and older animals are especially at risk. The correct answer is to insulate the cage with blankets and cardboard and place towel-wrapped hand warmers or a hot-water bottle against the outside or sides of the nest box, creating both a warm spot and a place to retreat from it. Fill a nest box the two can huddle in with thick hay. Hand warmers placed directly in the nest box cause low-temperature burns and, if chewed open, poisoning from the contents. Placing them on a hot-water bottle burns them, and with no escape they overheat. Waiting until morning lets body temperature keep falling, and by the time they cannot move it is often too late. After power returns, check appetite and droppings, and see a vet if they are not eating.

IssuesWinter heating relied entirely on electrical appliances, with no non-electric backup plan. The owner had items like hand warmers but did not know how to use them safely (wrap in a towel, no direct contact).

ImprovementKeep disposable hand warmers, a hot-water bottle, blankets, and cardboard together near the cage for emergencies, with written instructions (wrap and place against the outside). In winter fill the nest box with thick hay in a design that lets several animals huddle. Keep a battery thermometer for checking temperature during outages.

In a household with three degus, the 5-year-old child has had diarrhea and fever for two days. The child helps clean the cage every day and often eats snacks afterward without washing hands. One of the degus has had soft stool for the past few days. The owner is agonizing over whether to give up the degus.

What is the most appropriate response?

1. Assume the degus are the cause, rehome them the same day, and throw away the cage
2. Take the child to a pediatrician and mention the degus, have the degu with soft stool seen by a vet, and enforce hand-washing after cleaning
3. Treat the child's diarrhea as a cold and continue contact and cleaning help as before
4. Give all the degus small doses of human antibiotics to eliminate the source

AnswerB. Take the child to a pediatrician and mention the degus, have the degu with soft stool seen by a vet, and enforce hand-washing after cleaning

ExplanationDegu droppings, urine, and dirty cages can carry Salmonella, which infects people who eat or drink without washing their hands, causing diarrhea and fever. Children and the elderly are prone to severe illness. The correct answer is to take the child to a pediatrician, say that the family keeps degus and the child helps clean the cage, and get tested; have the degu with soft stool get a fecal test at the vet; and strictly enforce no eating while cleaning and hand-washing afterward. Rehoming them on an assumption solves nothing without disinfecting the already contaminated environment and treating the child. Dismissing it as a cold and continuing contact spreads it to the family. Self-administering human antibiotics destroys the degus' gut flora, breeds resistant bacteria, and the doses are dangerous.

IssuesA young child was allowed to help clean the cage without being taught to wash hands and not eat during cleaning. The degu's soft stool was taken lightly and the zoonotic risk was not recognized.

ImprovementHave adults do the cleaning, and always wash hands with soap after the child touches the animals. Establish rules: no eating during cleaning, and no washing cage items in the kitchen sink. See a vet if a degu's soft stool lasts over three days, and tell the doctor about the pets whenever a family member is ill.

An owner three months into keeping a degu. Every time they change the hay and sand during cage cleaning, they cannot stop sneezing; recently red hives appear on their arms after holding the degu, and at night they feel mild shortness of breath. The degu itself is healthy with normal skin. The owner thinks they will get used to it and keeps cleaning without a mask.

What is the most appropriate response?

1. It will go away once you get used to it, so continue cleaning and handling as before
2. Assume you caught a disease from the degu and have the vet treat it with antibiotics
3. See a doctor, clean with ventilation and a mask, and take measures against dust from hay and sand
4. Bathe the degu to wash dirt out of its fur and reduce allergens

AnswerC. See a doctor, clean with ventilation and a mask, and take measures against dust from hay and sand

ExplanationDust from degu fur, hay, and bathing sand causes allergies in people; beyond sneezing and hives, shortness of breath is a dangerous sign that can lead to an asthma attack. The correct answer is first to see a doctor (general practice or allergy clinic) to identify the cause, then take measures such as cleaning with ventilation while wearing a mask and gloves, switching to low-dust hay, and covering the sand bath. Expecting to "get used to it" worsens the symptoms and can lead to severe asthma. The degu is healthy with no signs of infection, so there is no reason to give antibiotics. Water baths are strictly forbidden for degus; they make the animal ill, and in any case much of the allergen comes from the hay and sand.

IssuesThe owner tried to solve allergy symptoms by getting used to them, and took the dangerous sign of shortness of breath lightly. They did not know hay and sand dust could be the cause and took no ventilation or mask precautions.

ImprovementClean with ventilation while wearing a mask and gloves, then change clothes and wash hands. Choose low-dust hay and sand and keep the cage out of the bedroom. Install an air purifier, and if symptoms persist, discuss with a doctor how to continue keeping the degu.

In the morning your 5-year-old degu is lying on its side on the cage floor. It does not respond to its name or to a light touch of a finger on its nose, and you cannot see any chest movement with the naked eye. The body is still warm. A piece of hay is visible in its mouth. The family is upset and starts filming with their phones, and the owner is unsure what to do.

Which is the most appropriate first action?

1. Start chest compressions by pressing hard with your thumb, continue for 10 minutes, then see a vet
2. Clear the foreign matter from the mouth with a cotton swab, keep it warm in a towel, and transport while phoning the clinic
3. Conclude it has died, lay it quietly to rest, and discuss with the family
4. Pour water into the mouth to revive it, and if it responds, return it to the cage

AnswerB. Clear the foreign matter from the mouth with a cotton swab, keep it warm in a towel, and transport while phoning the clinic

ExplanationA degu's normal breathing rate is about 100 per minute and heart rate about 270, so fast that a layperson can hardly confirm chest movement or heartbeat. A warm body leaves a chance of recovery. The correct answer is to clear the foreign matter from the mouth with a cotton swab to open the airway, wrap it in a towel for warmth, phone the clinic for instructions, and transport it immediately. Degus are small with fragile bones, so hard thumb compressions cause rib fractures and organ damage. Light one-finger chest compressions at about 100 per minute are only for shallow breathing and are done during transport. Deciding on your own that it has died is premature; there is room for resuscitation until a vet confirms. Pouring water into an unconscious animal causes aspiration. Filming is a classic error that delays action.

IssuesThe family had not prepared for a sudden decline in an elderly 5-year-old or shared the emergency procedure (airway, warmth, phone, transport). The owner could not stop the family from filming and lost time.

ImprovementPost a written emergency procedure on the cage and assign family roles (phone, transport). Keep an emergency kit with cotton swabs, a towel, hand warmers, and a small carrier. Have elderly degus checked every six months and discuss the risk of sudden decline with the vet.

Your 2-year-old degu apparently caught its tail in a gap between levels of the multi-level cage; the skin near the base of the tail is torn and bleeding. Blood is spreading across the bedding and the degu is running around, flinging blood about. It is 11 p.m., and the owner, not knowing how to stop the bleeding, is about to pull on the tail to examine it.

What is the most appropriate response?

1. Press the base of the tail with clean gauze to stop the bleeding, keep it warm, and go to the emergency (after-hours) animal hospital
2. Pull the tail to check how deep the wound is, and see a vet if it is deep
3. Let it run to improve circulation until the bleeding stops, and see a vet in the morning
4. Tie a thread tightly around the base of the tail to stop the bleeding and leave it until morning

AnswerA. Press the base of the tail with clean gauze to stop the bleeding, keep it warm, and go to the emergency (after-hours) animal hospital

ExplanationWith a bleeding tail, pulling on it causes the skin to slip off and expose bone, a tail slip that makes the injury far worse. The correct answer is to cup the body in both hands to restrain it, press the base of the tail gently with clean gauze for a few minutes to stop the bleeding, keep it warm in a towel, and go to the emergency (after-hours) animal hospital. In a degu this small even minor blood loss can lead to anemia or shock, so it must not be left running around. A tight thread cuts off circulation, the tail dies, and it bleeds again when removed. At the clinic, describe the amount of blood, the time, and how it was caught; a photo of the wound, if possible, speeds treatment. If it becomes limp or stops eating after the bleeding stops, consider its condition to be worsening.

IssuesThe owner had not inspected the gaps between cage levels and kept using a structure that could trap the tail. Not knowing how to stop bleeding, they nearly took the most dangerous action of pulling the tail. The emergency clinic's number had not been checked either.

ImprovementInspect gaps in cage levels and steps with a finger, and fill any that a tail or leg could enter with wood. Keep an emergency kit with gauze, a towel, and a carrier, and write out the bleeding-control procedure. Share the emergency clinic's number and route with the family.

A 1-year-old degu. A week ago you began giving a thumb-sized piece each of raw carrot and sweet potato daily "for nutrition." For three days the droppings have been soft and losing shape, and the fur around the rear is soiled. It eats hay but less than before, and drinks a lot. It still looks lively, but the cage smells stronger than usual.

What is the most appropriate response?

1. Reduce water to firm up the droppings and replace the vegetables with softened pellets
2. Give a little yogurt to settle the gut and keep feeding the vegetables
3. It is lively, so do not worry; increase the vegetables further for more nutrition
4. Stop the vegetables, return to a diet of mainly hay and water, and if it does not improve within a few days, see a vet with a stool sample

AnswerD. Stop the vegetables, return to a diet of mainly hay and water, and if it does not improve within a few days, see a vet with a stool sample

ExplanationCarrot and sweet potato are high in sugar and water, upsetting the degu's gut flora and causing soft stool, and they also lead to diabetes. The correct answer is to stop the vegetables at once, return to a diet based on timothy hay and water, and see a vet with a stool sample if the droppings have not normalized in 2–3 days, appetite falls, or it becomes limp. Reducing water fails to replace fluid lost through diarrhea and causes dehydration. Yogurt contains lactose and sugar, is unsuited to herbivorous rodents, and makes things worse. More vegetables only strengthens the cause. Persistent soft stool may also indicate parasites or bacterial infection, so get a fecal test.

IssuesThe owner applied the general idea that "vegetables are healthy" to a degu, for which sugar is forbidden. They watched three days of soft stool and a soiled rear without changing the diet that caused it.

ImprovementBase the diet on unlimited timothy hay, with pellets at about 5% of body weight morning and evening, and treats limited to a tiny amount of dried wild greens. Do not give raw vegetables or fruit. Check the shape and number of droppings every morning, and if soft stool lasts over two days, review the diet and see a vet.

A 2.5-year-old degu. During your weekly dental check you notice the incisors, once a clean orange, have turned whitish from the base. They are not especially long, but the lower teeth look slightly shifted sideways. It eats hay a little more slowly than before, and there is no drooling yet. You think the white teeth might actually look nicer.

Which is the most appropriate judgment of this observation?

1. White teeth are a sign of declining health; review the diet and see a vet within a few days
2. White teeth are a sign of health, so do nothing and continue the regular checks
3. Tooth color comes from pigment in the hay, so try a different brand of hay
4. Give hard nuts daily to polish the teeth and keep them white

AnswerA. White teeth are a sign of declining health; review the diet and see a vet within a few days

ExplanationHealthy degu teeth are orange to yellow-orange; whitening is a sign of deteriorating health such as malnutrition, dental disease, or internal illness. The sideways shift and slower eating also suggest early malocclusion. The correct answer is to check that the diet is hay-based and see a vet within a few days to have the teeth and overall condition examined. Mistaking white teeth for health delays detection of the problem. Tooth color does not come from hay pigment, so changing brands solves nothing. Nuts are high in fat and sugar, cause diabetes and obesity, and hard foods risk cracking the teeth. If drooling or reduced appetite appears, switch to a same-day visit.

IssuesThe owner judged by human standards that white teeth look clean and did not know the normal tooth color unique to degus. The weekly dental check was a good habit, but with unclear criteria it did not lead to action.

ImprovementShare with the family that healthy degu teeth are orange, and decide that whitening, overgrowth, or misalignment means a vet visit. Photograph the teeth at each check to compare with earlier ones. Never run out of hay, and provide several chew sticks to ensure tooth wear.

A 7-year-old degu. Both eyes are clouded white, and the vet has diagnosed cataracts with almost no vision. Diabetes has been ruled out; it is age-related. Lately it bumps into things in the cage and takes a long time to find its food. Feeling sorry for it, the owner is thinking of rearranging the cage to make it more spacious.

Which is the most appropriate action for the owner?

1. It cannot see so they are unnecessary: remove the wheel and all the multi-level steps for one wide flat floor
2. Buy human cataract eye drops online and apply them daily to cure the eyes
3. Replace the cage with a large new one and refresh the whole layout to add stimulation
4. Keep the layout unchanged, lower the levels, and fix the position of food and water so it can live by scent and memory

AnswerD. Keep the layout unchanged, lower the levels, and fix the position of food and water so it can live by scent and memory

ExplanationA degu that has lost its sight can still get around using scent and a memorized map of its cage. The correct answer is to keep the layout unchanged, lower any levels that pose a fall risk, and fix the positions of food, water, and the sand bath so it can navigate by scent and memory. Suddenly changing the cage or rearranging everything wipes out the learned map, leaving it unable to move, at risk of falls, and unable to reach its food. Removing all the equipment causes under-stimulation and lack of exercise; a wheel with a solid side is still usable. Human eye drops have the wrong ingredients and concentrations, and using them without veterinary advice is dangerous. Weigh it regularly and see a vet within a few days if food intake drops.

IssuesThe owner did not understand that their well-meant idea of a "bigger, newer environment" would be the greatest stressor for an animal that has lost its sight. No daily observation criteria had been set for the elderly animal.

ImprovementFor elderly or visually impaired degus, fix the layout and put everything back in exactly the same place after cleaning. Lower the levels and add steps within reach of any fall. Speak before touching so as not to startle it. Continue twice-monthly weigh-ins and six-monthly check-ups.

A 4-year-old degu. At the monthly weigh-in, it has dropped from 240 g last month to 220 g this month. It looks unchanged, appears to be eating hay, and water intake is the same. However, the others have been grooming it more than before, and its coat seems to have lost its shine. The owner wonders if it is just the season.

What is the most appropriate response?

1. An 8% weight loss in a month is serious; observe how it eats and its droppings, and see a vet within a few days
2. It has lost weight, so fatten it up by doubling the pellets and adding dried fruit
3. It looks healthy, so wait for next month's weigh-in and see a vet if it has dropped again
4. It is natural seasonal variation, so just record it and do nothing in particular

AnswerA. An 8% weight loss in a month is serious; observe how it eats and its droppings, and see a vet within a few days

ExplanationFor a 240 g degu, losing 20 g in a month is a drop of about 8%, a serious change equivalent to a person losing over 5 kg. Appearance and seeming to eat are unreliable; reduced intake from malocclusion, diabetes, kidney disease, or tumors is often hidden. The correct answer is to observe whether it is actually chewing and swallowing hay and how large and numerous the droppings are, and see a vet within a few days to find the cause. More pellets and dried fruit mean excess sugar and lead to diabetes. Waiting another month means further weight loss and fewer treatment options. The good habit of regular weighing must be turned into action.

IssuesWeighing was a good habit, but the owner had no threshold for how much loss should trigger a vet visit. They tended to let the impression of "looks fine" override the numbers.

ImprovementWeigh twice a month and set a rule: a loss of 5% or more, or two consecutive drops, means a vet visit. Check daily how it eats hay (chewing speed, dropping it) and the size of droppings. Keep the records on your phone so the trend can be shown at the clinic.

A 3-year-old degu. You provide the sand bath daily, but for about two weeks the fur on its back and hips has been greasy and clumped, with small red patches on the skin. The same sand has been reused for a month, and a humidifier keeps the room at 70% humidity. The degu bathes less often and sometimes scratches as if itchy.

What is the most appropriate response?

1. Wash it with baby shampoo to remove the oil and dry it with a hair dryer
2. Brush it thoroughly every day to remove the oil
3. It has probably grown bored of bathing, so remove the container and watch
4. Replace the sand with fresh dry sand, lower humidity to 40–60%, and see a vet within a few days if the redness spreads

AnswerD. Replace the sand with fresh dry sand, lower humidity to 40–60%, and see a vet within a few days if the redness spreads

ExplanationDegus are arid-habitat animals that keep clean by removing skin oil through dust baths. Damp or worn-out sand does not remove the oil, and at 70% humidity the oil cakes and becomes a breeding ground for dermatitis. The correct answer is to replace the sand with fresh dry sand provided daily, lower humidity to 40–60%, and see a vet within a few days if the redness spreads, hair loss or dandruff appears, or the itching is severe. Washing with water or shampoo is strictly forbidden; it strips too much oil, damages the skin, and chills the animal. Brushing is unnecessary for degus and may injure the skin. Removing the sand bath lets even more oil build up and worsens the condition.

IssuesThe owner reused the sand for a long time and kept the humidity high with a humidifier for human comfort. They lacked understanding of how extremely damp-sensitive degus are and how central dust bathing is to their health.

ImprovementCheck the sand daily, replace it if dirty or damp, and do a full change at least weekly. Put a thermo-hygrometer on the cage and keep humidity at 40–60% with a dehumidifier. Do not use a humidifier in the degu's room. Check skin and coat once a week.

A 3-year-old degu. It picks up hay but now chews only on the right side and drops it in pieces midway. It eats pellets normally and there is no drooling yet. Its weight is unchanged from last week. For a week it has been rubbing its face with its claws more often, and the right eye is slightly watery. The owner thinks the teeth must be fine since there is no drooling.

Which is the most appropriate judgment of this situation?

1. Treat it as an early sign of cheek-tooth trouble, soften the pellets, and see a vet that can do dental work within a few days
2. No drooling means it is not a dental problem; use eye drops and watch the tearing
3. The hay must be poor quality, so switch to softer second-cut hay and watch
4. Face rubbing means it needs more dust baths, so increase them and wait

AnswerA. Treat it as an early sign of cheek-tooth trouble, soften the pellets, and see a vet that can do dental work within a few days

ExplanationChewing on one side, dropping hay, rubbing the face, and tearing in one eye are early signs of overgrown cheek teeth or root problems pressing on the tear duct or cheek. Drooling is a symptom of advanced disease, so its absence is no reassurance. The correct answer is to avoid hard food and feed softened pellets while seeing a vet within a few days that can examine the cheek teeth and perform dental work. Caught early, filing the teeth may be enough; left to progress, it leads to tooth-root abscesses and eye damage. Eye drops alone leave the cause in place. Switching to softer hay wears the teeth even less and is counterproductive. Dust baths have nothing to do with the face rubbing and only waste time.

IssuesThe owner judged by the single symptom "drooling = dental problem" and missed the early signs in eating, tearing, and face rubbing. They had not looked up a vet that does dental work in advance.

ImprovementObserve eating daily (which side it chews, dropping food, speed) and decide that any change means suspecting the teeth. Remember that tearing, eye discharge, and face rubbing are also dental signs. Find an animal hospital that does dental work in advance and have a dental check every six months.

You use a metal hamster wheel with no solid side. At night the wheel suddenly stopped and you heard shrieking. Your 1-year-old degu's left hind leg has slipped into a gap in the wheel's frame, and the wheel has turned half a rotation, twisting the leg. The foot is starting to turn purple, and the degu is struggling, moving the wheel even more.

Which is the most appropriate first action?

1. Turn the wheel backward to return the leg to its original position, and once free, watch it in the cage
2. Grab the degu and pull with all your strength to free the leg, then disinfect it
3. It is struggling from pain, so leave it 30 minutes to calm down and wait for it to free itself
4. Hold the wheel still with your hand, support the body, slowly widen the gap to free the leg, and see a vet the same day

AnswerD. Hold the wheel still with your hand, support the body, slowly widen the gap to free the leg, and see a vet the same day

ExplanationEvery time the wheel moves, the twisting and the risk of fracture increase, so the correct answer is first to hold the wheel still with one hand, support the body with the other to stop the struggling, widen the gap or remove the whole wheel from the cage to free the leg, and because of the purple discoloration and swelling, see a vet the same day. Turning the wheel backward winds the leg in further. Pulling the leg out causes fractures and skin tearing. Leaving it for 30 minutes lets the tissue of the leg, with its blood supply cut off, die, which can require amputation. Small hamster wheels and wheels without a solid side are dangerous for degus; replace with one at least 30 cm in diameter with a solid side.

IssuesThe owner repurposed a wheel made for other small animals without recognizing the dangers of a design unsuited to a degu's size and gait. The gaps in the wheel's frame that could trap a leg had not been checked.

ImprovementReplace the wheel with a solid-plate type at least 30 cm in diameter, with a solid side and no gaps, fixed against a wall to prevent tipping. Check new equipment for safety by probing the gaps with a finger before installing. Keep tools nearby so the wheel can be removed in an emergency.

Your 2-year-old degu jumped out of your arms while being held and landed face-first on the wooden floor. It started moving right away, but there is blood around the mouth, and on checking, one lower incisor is broken off about halfway. It tries to pick up hay but drops it, and keeps working its mouth. The upper incisors look intact.

What is the most appropriate response?

1. Press the inside of the mouth lightly with clean gauze to stop the bleeding, soften the pellets, and see a vet within a few days
2. To even out the length, trim the opposite tooth to match with household nail clippers
3. Teeth grow back, so do nothing and feed hard pellets and hay as usual
4. It won't eat because of the pain, so smear dried-banana paste in its mouth for nutrition

AnswerA. Press the inside of the mouth lightly with clean gauze to stop the bleeding, soften the pellets, and see a vet within a few days

ExplanationDegu incisors grow continuously, so the chipped tooth itself will regrow, but if the upper and lower teeth no longer meet, the remaining tooth overgrows abnormally, leading to malocclusion and mouth wounds. A cracked root causes an abscess. The correct answer is to press the bleeding spot lightly with gauze, keep it able to eat with softened pellets and softened hay, and see a vet within a few days to check the bite and the tooth root. Cutting teeth with household nail clippers splits them lengthwise and damages the root. Leaving it and feeding hard food injures the mouth until it cannot eat. Dried banana is far too sugary and an unsuitable way to provide nutrition.

IssuesThe owner held the degu while standing, at a height from which it could jump. After the fall they nearly assumed "it moved, so it's fine" and had no habit of checking the mouth.

ImprovementHold the degu while sitting on the floor so any jump is from a low height. After a fall, always check the mouth, legs, and tail, and treat a chipped tooth as a vet-visit sign. Always be ready to prepare softened pellets, and know a vet that does dental work.

You reached into the cage to take out your 3-month-old degu, which you brought home two weeks ago, and it bit your finger hard. The pain makes you want to move your hand, but the degu stays clamped on. Your child is shouting next to you, and you are about to jerk your hand away by reflex.

Which is the most appropriate first action?

1. Yank your hand out quickly, move away from the cage, and tap it to teach it not to bite
2. Scold it loudly and shake the cage to startle it into opening its mouth
3. Push your finger deeper into its mouth so it dislikes it and lets go
4. Stay still, relax, and offer hay to its mouth with your other hand to distract it

AnswerD. Stay still, relax, and offer hay to its mouth with your other hand to distract it

ExplanationShaking off or yanking away a bitten hand can break the degu's teeth or fling its body, causing serious injuries such as falls and tail slip. The correct answer is to stay still and relax despite the pain, support the chest with the other hand if needed to steady the body, offer hay or a chew stick at its mouth to distract it, and once it lets go, gently return it to the cage and leave it alone. Hitting, shouting, or shaking the cage instill fear, worsen biting, and destroy trust. Pushing the finger deeper makes it bite harder and injures both your finger and its mouth. Wash the bite under running water and disinfect, and see a doctor if it swells, feels hot, or becomes infected. Afterward, look for the cause of the bite (fear, pain).

IssuesOnly two weeks after arrival, during a period of strong wariness, the owner reached in from above like a predator. The child's shouting agitated the degu, and the family did not know what to do when bitten.

ImprovementUntil it is tame, do not reach in from above; offer hay from the side of the cage so it learns your scent. When picking it up, cup the whole body in both hands in a calm setting. Teach the children the bite procedure too (stay still, distract, do not scold).

Two weeks ago a bit of skin came off the tail, but having heard it would fall off naturally, you did not see a vet. This morning the last 3 cm of your 3-year-old degu's tail is black, dry, and hard, and the boundary is moist and smells bad. The degu keeps biting at its tail and its appetite is falling. The boundary is slightly swollen.

What is the most appropriate response?

1. It is about to fall off naturally, so wait until it does
2. Suspect necrosis and infection, cover it with gauze without touching, and see a vet the same day
3. Cut off the black part yourself with scissors, disinfect, and bandage it
4. Spray human antiseptic on it daily to kill the smell and watch

AnswerB. Suspect necrosis and infection, cover it with gauze without touching, and see a vet the same day

ExplanationAn untreated tail slip leaves the exposed part to die, and the moist discharge, smell, and swelling at the boundary are signs of bacterial infection. If the infection spreads through the body it causes fatal sepsis, and the falling appetite marks its beginning. The correct answer is to cover it lightly with clean gauze without touching it and see a vet the same day for removal of the dead tissue and antibiotic treatment. Waiting for it to fall off allows the infection to progress. Cutting it off at home worsens bleeding and infection, and a procedure without anesthesia causes extreme suffering. Human antiseptic spray irritates the tissue and causes poisoning if licked. The manual also says to see a vet the same day for tail slip and not to wait for natural shedding.

IssuesThe owner believed the fragmentary information that "the tail falls off on its own" and did not see a vet at the time of the tail slip two weeks earlier. They failed to recognize the visible progression of necrosis and infection, leaving it until the appetite dropped.

ImprovementDecide that any tail slip, however minor, means a same-day vet visit, and trust the vet over online information. Strictly never hold or pull the tail, and inspect cage gaps. Check an injured animal daily for smell and swelling and see a vet immediately if anything changes.

Three days ago your two cage mates fought and one (age 2) got a small bite wound under the jaw. The bleeding stopped quickly and it seemed fine, so you did not see a vet. Today the area under the jaw has swollen to about half the size of a ping-pong ball, feels hot to the touch, and the degu seems to have trouble eating hay. The center of the swelling is slightly soft.

What is the most appropriate response?

1. It is full of pus, so lance it with a needle at home, drain it, disinfect, and watch
2. Warm the swelling with a hot towel to improve circulation and wait for it to go down
3. The wound has healed, so treat the swelling as constitutional and watch for a week
4. Suspect an abscess and see a vet the same day for lancing and antibiotic treatment

AnswerD. Suspect an abscess and see a vet the same day for lancing and antibiotic treatment

ExplanationEven when the skin wound from a bite is small, the teeth penetrate deeply, bacteria enter under the skin, and an abscess often forms days later. A hot swelling, a soft center, and difficulty eating are classic for an abscess. The correct answer is to see a vet the same day for lancing, flushing, and antibiotics; a jaw abscess that reaches the tooth roots leads to malocclusion and bone infection, and untreated it risks sepsis. Lancing at home spreads the infection and causes serious injury when the animal struggles in pain. Warming spreads the inflammation. Waiting a week as "constitutional" lets the abscess rupture and leave a large skin defect. If the fighting continues, consider separating them and review the cause (number of dishes, compatibility).

IssuesReassured because the bleeding stopped on the day, the owner did not know an abscess could form days later. The cause of the fight was not analyzed, and keeping them together left a risk of recurrence.

ImprovementEven a small bite wound means a same-day vet visit to flush it and decide on antibiotics, followed by a week of daily checks for swelling and heat. Provide more dishes and nest boxes than animals, and house pairs that keep fighting in separate cages.

To show a guest, you were holding your 1-year-old degu at chest height while standing. When the guest reached out, it startled, leapt from your arms, and fell about 1.2 m to the floor. It froze for a moment, then ran toward the cage and hid in the nest box. It will not come out when called. No bleeding is visible.

What is the most appropriate response?

1. Even though it ran off, internal or bone injuries are possible, so rest it and see a vet the same day
2. It ran into the nest box, so judge it unhurt and take it out to show the guest again
3. Startling it was the problem, so pick it up and keep stroking it to calm it
4. Open the nest box, feel the whole body, and relax if nothing seems painful

AnswerA. Even though it ran off, internal or bone injuries are possible, so rest it and see a vet the same day

ExplanationFor a degu of about 200 g, a 1.2 m fall is more than six times its body length, and even if it can run right after landing, fractures, internal injuries, and tail damage may be hidden. The correct answer is to leave it quietly resting in the nest box, observe its movement, appetite, and droppings, and see a vet the same day for X-rays and an examination. If it holds up a leg, breathes fast, or will not eat, switch to an immediate visit. "It ran, so it's unhurt" is the most common misconception in fall accidents. Taking it out again or picking it up and stroking it puts heavy strain on an animal in shock. Feeling the whole body worsens any fracture.

IssuesThe owner handled the degu standing at chest height in a situation with a startling factor, a guest. They did not understand that a startled degu will jump even from a height.

ImprovementAlways hold the degu while sitting on the floor, on your lap or at a low height. Do not force handling when guests visit; let them look through the cage. Decide that after any fall it sees a vet even if it can run, and know a clinic that can see it the same day.

Your medium-sized dog, kept in the living room, pressed its nose against the degu cage on the floor and barked furiously. Your two degus (ages 1 and 2) froze in a corner of the cage; one is wide-eyed, completely motionless, and breathing fast. The dog chewed the cage door and the wire is slightly bent. You scolded the dog and made it sit in the corner of the room.

Which is the most appropriate next step?

1. The dog has calmed down, so let it spend time near the cage so the degus get used to it
2. Worried about the frozen degu, take it out right away and hold it to reassure it
3. The dog has been scolded so the same room is fine; leave the cage where it is
4. Move the cage to a room the dog cannot enter, keep it dark and quiet, and check responsiveness and appetite after 1–2 hours

AnswerD. Move the cage to a room the dog cannot enter, keep it dark and quiet, and check responsiveness and appetite after 1–2 hours

ExplanationTo a degu, a dog is a predator, and its sight, smell, and barking alone trigger a strong stress response. Freezing motionless with rapid breathing is fear-induced immobility that can lead to shock, strain on the heart, and in extreme cases death. The correct answer is to move the whole cage to a room the dog cannot enter, keep it dark and quiet, and after 1–2 hours check movement, appetite, and droppings. If it is still not moving or eating after several hours, see a vet the same day. Trying to habituate them to the dog forces coexistence with a predator, and chronic stress leads to illness. Taking out and holding a frozen degu adds fear and causes bites or jumping accidents. Scolding the dog does not erase its instincts, and in the same room it will happen again.

IssuesThe owner ignored the basic rule of keeping degus in a separate room from dogs, cats, and ferrets, and the cage on the floor was within the dog's reach. They took the degu's freezing lightly and did not know how serious psychological shock can be.

ImprovementKeep degus in a separate room from dogs and cats, with the door closed to block scent as well. Place the cage on a stable stand off the floor and double-secure the door. Choose a location where the dog's barking does not reach, and put the dog in another room before free-roam time.

During free-roam time your 2-year-old degu squeezed into the gap (about 3 cm wide) between the wall and a bookcase and got its body wedged deep inside, unable to move. It keeps shrieking. The bookcase is heavy with books, and through the gap you can see only the tail and hind legs; you cannot reach it. You are wondering whether to pull it out by the tail.

What is the most appropriate response?

1. Take hold of the visible tail and pull it out slowly
2. Insert a vacuum-cleaner hose and suck it out
3. Remove the books to lighten the bookcase, slide it slowly parallel to the wall to widen the gap, and wait for it to come out on its own
4. Shout and clap toward the gap to startle it into backing out

AnswerC. Remove the books to lighten the bookcase, slide it slowly parallel to the wall to widen the gap, and wait for it to come out on its own

ExplanationPulling a wedged degu by the tail strips the skin off (tail slip) and wedges the body tighter, causing fractures. The correct answer is to remove the books to lighten the bookcase, slide it slowly parallel to the wall to widen the gap, and wait for the degu to come out by itself. When it does, cup it in both hands and check the legs and tail for swelling. If it will not come out, lure it with favorite hay or the sand bath placed nearby. A vacuum causes suffocation and severe impact that injures the internal organs. Shouting and clapping cause panic, driving it forward even deeper and restricting its breathing. After rescue, see a vet the same day if it drags a leg, the tail is injured, or it will not eat.

IssuesGaps between furniture and the wall in the free-roam room had not been blocked, leaving spaces a degu could squeeze into. The owner did not know the danger of pulling by the tail and nearly acted in haste.

ImprovementBefore free-roam time, inspect gaps between furniture and walls and behind appliances, and block them with cardboard or cushions. Confine the roaming area with a playpen. Share with the family the rule for a wedged degu: do not pull the tail, move the furniture, wait for it to come out on its own.

A 1-year-old degu. For several days it has been gnawing the rim of its plastic wheel, and this morning about 2 cm of the rim is missing, yet almost no fragments are on the floor. The droppings are slightly small and somewhat fewer. It eats hay but sometimes curls up as if bothered by its belly. There were no chew sticks in the cage.

What is the most appropriate response?

1. Remove the wheel, add chew sticks, record the number and size of droppings, and see a vet the same day if they keep decreasing or appetite drops
2. Plastic is not digested, so give oil to pass it out with the droppings
3. Keep it exercising on the wheel as usual until the fragments come out, and watch
4. Put a finger in its mouth and strike its back to make it vomit up the fragments

AnswerA. Remove the wheel, add chew sticks, record the number and size of droppings, and see a vet the same day if they keep decreasing or appetite drops

ExplanationDegus gnaw anything, and swallowed plastic fragments lodge in the intestine and cause a blockage. Small, scant droppings and curling up are early signs of impaired passage. The correct answer is to remove the plastic items, satisfy the urge to chew with chew sticks, keep the gut moving with hay and water, record the number and size of droppings, and see a vet the same day if they keep decreasing, appetite drops, or it sits hunched and still. With droppings already reduced, consulting the vet now is advisable. Oil is ineffective and causes diarrhea. Forcing exercise does not move fragments through a nearly blocked gut. Degus cannot vomit, and trying to make them only injures the mouth and esophagus.

IssuesThe owner used a chewable plastic toy and provided no chew sticks. They did not remove it when the gnawing began and did not check where the fragments had gone.

ImprovementUse wooden, ceramic, or metal equipment in the cage and avoid plastic. Provide several chew sticks to satisfy the urge to gnaw. Inspect chewed items daily; if the amount missing does not match the fragments on the floor, suspect ingestion and watch the droppings.

After returning your 1.5-year-old degu to its cage at the end of free-roam time, you found under the table a rubber band it had been carrying in its mouth, cut in half. You cannot tell whether it swallowed any. The degu is bathing happily for now. You read online that small objects pass with the droppings and feel reassured.

What is the most appropriate response?

1. As the website says, it will pass with the droppings, so do nothing and carry on as usual
2. To be safe, reduce the hay to empty the stomach so the object can move through
3. Give a small dose of human laxative to speed up passage
4. Provide plenty of hay and water, record the number and size of droppings and appetite for about three days, and see a vet the same day if they decrease

AnswerD. Provide plenty of hay and water, record the number and size of droppings and appetite for about three days, and see a vet the same day if they decrease

ExplanationA rubber band is elastic and readily tangles in the intestine, making it a foreign body prone to causing blockage. Even if the degu is lively now, if it lodges in the gut, droppings decrease, appetite falls, and the animal deteriorates suddenly 1–2 days later. The correct answer is to provide plenty of hay and water to keep the gut moving, record the number and size of droppings, appetite, and abdominal bloating for about three days, and see a vet the same day if droppings decrease or shrink, it stops eating, or it sits hunched and still. If ingestion seems likely, consult the vet early. Trusting online information and doing nothing delays the response when it deteriorates. Reducing hay shuts down the gut and causes a blockage. Human laxatives are dangerously dosed and cause intestinal rupture if there is a blockage.

IssuesThe owner did not clear under the table before free-roam time and left small items like rubber bands lying around. Reassured by fragmentary online information, they had set no observation or vet-visit criteria.

ImprovementBefore free-roam time, inspect the floor at a low eye level and clear rubber bands, plastic, cloth, and small items. Agree as a family that possible ingestion means three days of droppings observation and a same-day vet visit if they decrease. Build a relationship with your regular vet so you can phone for advice.

In mid-June the rain has continued and the indoor hygrometer reads 80%. You assumed the 24°C room temperature was fine, but your two degus (ages 1 and 2) are bathing less and their fur is damp and clumped. The hay bedding has gone limp, and the cage gives off a musty smell. One degu keeps scratching itself with its hind leg.

What is the most appropriate response?

1. Lower humidity to 40–60% with a dehumidifier or the air conditioner's dry mode, and fully replace the bedding and sand with dry material
2. The room temperature is correct, so there is no problem; wait until the rain stops
3. Blow warm air from a hair dryer into the cage to drive off the moisture
4. Wipe the body lightly with lukewarm water to remove the greasiness and dry it

AnswerA. Lower humidity to 40–60% with a dehumidifier or the air conditioner's dry mode, and fully replace the bedding and sand with dry material

ExplanationDegus are arid-habitat animals that are highly sensitive to damp; the proper humidity is 40–60%. At 80% humidity the coat's oil cakes, dust baths lose their effect, dermatitis and fungal infections develop easily, and bedding grows mold. The correct answer is to lower humidity with a dehumidifier or the air conditioner's dry mode, fully replace the damp bedding and sand with fresh dry material, and ensure ventilation. If the scratching degu develops red skin or hair loss, see a vet within a few days. Watching only temperature and ignoring humidity is a classic oversight. Warm air from a dryer risks heatstroke and burns. Wiping with water strips oil, chills the animal, and adds even more moisture.

IssuesThe owner was careful about temperature but neglected humidity, unaware of how rainy-season damp affects a degu's skin and bedding. They did not check the bedding until the cage smelled musty.

ImprovementPut a thermo-hygrometer on the cage and keep humidity at 40–60% with a dehumidifier. In the rainy season and summer, change bedding and sand more often and check daily for damp. Place the cage in a well-ventilated spot away from wet areas and windows.

On a winter night a major earthquake strikes, the power goes out, and aftershocks continue. The municipality issues an evacuation order and the family will shelter at the nearby elementary school. Your two degus (age 3) are safe in their cage, but the multi-level cage is close to toppling. The shelter allows pets, but the cage may not be allowed inside. You have a small carrier, hay, a water bottle, and hand warmers at hand.

What is the most appropriate action?

1. Leave the degus at home with plenty of hay and water and come back to check in a few days
2. They would be a nuisance at the shelter, so open the cage and release them to fend for themselves
3. Carry the whole large multi-level cage to the shelter and keep it outdoors
4. Put both degus in the small carrier lined with hay and evacuate together with towel-wrapped hand warmers, hay, and water

AnswerD. Put both degus in the small carrier lined with hay and evacuate together with towel-wrapped hand warmers, hay, and water

ExplanationLeft at home in a winter outage, they face hypothermia below 10°C and being crushed under a cage toppled by aftershocks. The correct answer is to put both degus in the small carrier lined with hay (together if compatible, so they can huddle for warmth) and evacuate with them, taking towel-wrapped hand warmers, hay, the water bottle, and pellets. Cover the carrier with a towel to keep it dark, and at the shelter place it somewhere quiet and not cold. Releasing them is fatal: captive animals cannot survive, they are taken by raptors and cats, and they harm the ecosystem. A multi-level cage is unsuited to transport, and outdoors they would freeze. At the shelter, keep them away from dogs and cats, and if they do not eat for several days, find an animal hospital.

IssuesThe plan for evacuating the degus in a disaster and the carrier and warming supplies were vague, and the multi-level cage was not secured against toppling. The owner had not learned the concept of evacuating together with pets.

ImprovementPack a small carrier, a week's hay and pellets, a water bottle, hand warmers, and towels in an emergency go-bag. Anchor the multi-level cage to the wall and keep heavy items off the top level. Check the municipality's rules on evacuating with pets and what form of housing the shelter allows.

On a sunny April day the room thermometer reads 22°C. Thinking brighter was better, you had placed the cage by a south-facing window; at 2 p.m. direct sunlight hits the nest box on the top level, and your 3-year-old degu inside is limp and breathing through its mouth. The wood of the nest box is hot to the touch and the cage wire is warm. The degu on the lower level is fine.

Which is the most appropriate first action?

1. The room is 22°C so heatstroke is impossible; treat it as a cold and keep it warm
2. Move the cage into the shade, take it out of the nest box, place a towel-wrapped ice pack nearby, and see a vet right now
3. Pour cold water over its body to cool it fast, and return it to the cage once dry
4. Open the window for a breeze, let it rest in the nest box, and wait until evening

AnswerB. Move the cage into the shade, take it out of the nest box, place a towel-wrapped ice pack nearby, and see a vet right now

ExplanationEven when the room temperature is fine, a spot in direct sunlight or inside a closed nest box can locally exceed 30°C, and a degu gets heatstroke. Mouth breathing and limpness are signs of severe heatstroke. The correct answer is to move the cage into the shade at once, take it out of the hot nest box, place a towel-wrapped ice pack nearby to cool it gradually, and see a vet right now. Judging by room temperature alone is dangerous; what matters is the temperature where the degu actually is. Pouring cold water causes shock and skin problems. Opening the window is meaningless while the sun keeps shining on it, and waiting until evening is too late. Even if it seems to recover, the internal organs may be damaged, so have a vet examine it.

IssuesThe owner applied the knowledge that "diurnal animals like a bright room" without the condition of avoiding direct sunlight. They looked only at the room thermometer and did not measure the local temperature inside the cage.

ImprovementPlace the cage out of direct sunlight and air-conditioner drafts, and avoid windowsills. Put thermometers on both the upper and lower levels of the cage. Recognize that a sunny windowsill is dangerous even in spring and fall, and block the sun with curtains or shade sheets.

You stored the degus' hay in the shed of your house, and wild mice got in, leaving droppings and urine around the hay bags. With a cut on your hand, you cleaned up bare-handed and are about to feed that hay to the degus rather than waste it. The shed floor is damp, and the degu cage is in the room next to the shed.

What is the most appropriate response?

1. The hay is fine once the soiled parts are removed, so feed it to the degus as is
2. Wild mice are harmless, so continue cleaning up and use the hay
3. Sun-drying the hay bags kills the germs, so use them a few days later
4. Discard the contaminated hay, clean up with gloves and disinfectant, wash the cut, and consult a doctor

AnswerD. Discard the contaminated hay, clean up with gloves and disinfectant, wash the cut, and consult a doctor

ExplanationWild rodent urine can contain Leptospira bacteria, which infect people through cuts that contact contaminated water or urine, causing fever and kidney damage. Degus can also catch the same bacteria, so hay soiled with droppings and urine must not be fed. The correct answer is to discard the contaminated hay, clean up wearing gloves and a mask with disinfectant, wash the cut under running water, and consult a doctor about having handled it with an open wound. Removing the soiled parts is not enough, as the whole bag may be contaminated. The idea that wild mice are harmless is wrong; they also carry Salmonella and parasites. Sun-drying does not fully kill the bacteria, and storing hay in a damp shed is itself a problem.

IssuesHay was stored in a damp shed, allowing wild mice to get in. The owner cleaned up droppings and urine bare-handed with a cut, unaware of the zoonotic risk.

ImprovementStore hay and pellets in sealed containers in a dry place indoors. Seal gaps in the shed and inspect regularly for signs of mice. Wear gloves when cleaning up animal waste, especially with cuts on your hands. Never let wild animals come into contact with the degus.

Last week you added a young degu from a pet shop to your existing three. You gave it a separate cage, but shared the sand bath, water bottle, and cleaning brush. The newcomer has had soft stool for three days and a dull coat. Today one of the original degus also has soft stool. The owner thinks it is just diarrhea from the change of environment.

What is the most appropriate response?

1. The change of environment is the cause, so move the newcomer into the main cage soon to settle it
2. Separate all equipment, care for the newcomer last, and see a vet the same day with stool samples from both
3. Give the two degus with soft stool small doses of human anti-diarrheal medicine
4. Combine everyone's sand baths into one and have them all bathe in disinfected sand at once

AnswerB. Separate all equipment, care for the newcomer last, and see a vet the same day with stool samples from both

ExplanationA newly acquired animal can bring in parasites and bacteria, and sharing the sand bath, water bottle, and cleaning tools is the most common route of spread. When the newcomer's soft stool is followed by soft stool in an original degu, strongly suspect transmission of an infection. The correct answer is to separate all equipment between the groups, care for the healthy group first and the newcomer last, and see a vet the same day with stool samples from both for fecal testing. Merging them spreads it to all. Human anti-diarrheals stop gut movement, trap toxins, and are dangerously dosed for a small degu. Combining the sand baths guarantees spread. Wash hands thoroughly between caring for each group.

IssuesThe owner gave the newcomer a separate cage but did not understand the purpose of quarantine and shared equipment. They optimistically attributed the soft stool to the change of environment without considering infection.

ImprovementQuarantine newcomers for 2–4 weeks with completely separate cages, sand baths, water bottles, and cleaning tools. Care for the healthy group first and wash hands in between. Get a health check and fecal test right after arrival, and begin preparing for introduction only if nothing is found.

At night your 4-year-old degu had a seizure and is lying on its side; it responds weakly when called, but its breathing is shallow and sometimes seems about to stop. There is nothing in its mouth. You reached the emergency (after-hours) animal hospital by phone and were told to come at once, but it is 30 minutes by car. A family member will drive, and you are unsure what to do during the trip.

Which is the most appropriate action during transport?

1. Give mouth-to-mouth breathing and keep pressing the chest hard with both hands for chest compressions
2. To avoid stimulating it, put it in the carrier and do nothing until you reach the hospital
3. Trickle sugar water into its mouth with a dropper to give it strength
4. Wrap it in a towel for warmth and, while breathing is shallow, press the chest lightly with one finger about 100 times per minute as you travel

AnswerD. Wrap it in a towel for warmth and, while breathing is shallow, press the chest lightly with one finger about 100 times per minute as you travel

ExplanationDegus are small with fragile bones, and hard two-handed chest compressions cause rib fractures and organ damage. The correct answer is first to wrap it in a towel for warmth and, while breathing is shallow and weak, support breathing by pressing the chest lightly with one finger at about 100 per minute during transport. If responsiveness or breathing changes, phone the hospital and follow instructions. Mouth-to-mouth damages the tiny lungs. Doing nothing lets body temperature and oxygen levels fall. Trickling sugar water into a semiconscious animal causes aspiration pneumonia, and sugar is harmful to degus. Keep the carrier dark, minimize jolting, and add a towel-wrapped hand warmer with no direct contact.

IssuesFaced with the emergency of a seizure, the owner did not know the life-saving measures suited to a degu (no hard pressing, warmth, light compressions) or how to prepare for transport. They had not checked the distance to the emergency clinic, causing hesitation over the order of actions.

ImprovementWrite out a degu life-saving procedure (clear airway, keep warm, one-finger compressions, transport while phoning) and post it on the cage. Keep a transport kit with a towel, hand warmers, and a small carrier, and confirm the emergency clinic's location and travel time with the family.

Late on a January night your 2-year-old degu has not eaten for over half a day, is limp, and its body feels cold. You decide to go to the emergency (after-hours) animal hospital, but it is 2°C outside and a 5-minute walk to the car. In the house you have a large wire cage, a small plastic carrier, disposable hand warmers, towels, and a cardboard box. Thinking warmer is better, you are about to put a hand warmer in as it is.

What is the most appropriate way to prepare for transport?

1. Line the small carrier with a towel, add a towel-wrapped hand warmer, and cover the whole carrier with cloth to keep it dark
2. Put the hand warmer in the carrier as it is so the degu can sit directly on it to warm up
3. Take the whole wire cage so it has a clear view even in the open air
4. Put the degu in your coat pocket and warm it with your body heat as you walk

AnswerA. Line the small carrier with a towel, add a towel-wrapped hand warmer, and cover the whole carrier with cloth to keep it dark

ExplanationWhen transporting a weak degu, warmth, darkness, and minimal jolting are key. The correct answer is to line the small carrier with a towel, add a disposable hand warmer wrapped in a towel so there is no direct contact, and cover the whole carrier with cloth to keep it dark. A bare hand warmer causes low-temperature burns and poisoning if chewed open, and inescapable heat is dangerous for a weakened animal. A wire cage exposes it to the cold air and visual stimuli, worsening its condition. A pocket risks falls, crushing, and escape, with no temperature control. Not eating for over half a day is an emergency; during transport, note its diet, droppings, and water intake so you can tell the vet.

IssuesThe owner understood the importance of warmth but not the danger of direct contact with a hand warmer, and had no transport carrier ready in advance. Leaving a degu that had not eaten for half a day until night was also a problem.

ImprovementKeep a transport kit (small carrier, towels, hand warmers, cloth cover) together at all times. Decide that not eating means a vet visit within half a day, and act during daytime hours. Confirm the route to the emergency clinic and warm up the car before loading the degu.

At 9 p.m. on Saturday your 3-year-old degu has eaten almost no hay since morning and has produced no droppings since midday. It is sluggish but responds when called. Your regular vet is closed on Sundays, and the emergency (after-hours) animal hospital is 40 minutes away by car. You are thinking of waiting until tomorrow morning and seeing your regular vet on Monday.

What is the most appropriate decision?

1. It is responsive, so wait until Monday and see your regular vet Monday morning
2. The emergency clinic is expensive, so manage at home with methods found online
3. No food and no droppings for over half a day is an emergency: keep it warm and go to the emergency (after-hours) animal hospital tonight
4. Give dried fruit to stimulate appetite, and if it eats, go to bed reassured

AnswerC. No food and no droppings for over half a day is an emergency: keep it warm and go to the emergency (after-hours) animal hospital tonight

ExplanationA degu that has not eaten or produced droppings for over half a day has gut stasis and often deteriorates suddenly before morning. The manual classes this as needing a same-day vet visit, and when it happens on a Saturday night the correct answer is to keep it warm and go to the emergency (after-hours) animal hospital tonight. Responsiveness is no guarantee of safety. Waiting 36 hours until Monday turns treatable gut stasis or blockage into a fatal one. Home remedies from the internet cannot diagnose the cause and only lose time. Dried fruit is harmful because of its sugar, and even if it eats a little, that is no proof the gut is moving. At the clinic, describe the diet and amounts, the state of the droppings, and when it stopped eating.

IssuesThe owner put off the vet visit on the grounds that "it's responsive" and "clinics are closed on weekends," unaware of the degu's half-day time limit. The cost and distance of the emergency clinic clouded the decision.

ImprovementAgree as a family that not eating or no droppings means a vet visit within half a day, and make a habit of noting the time. Look up the emergency clinic's number, route, and approximate cost in advance. Write your regular vet's closing days and an alternative clinic on the calendar.

After a period of excessive drinking and urination, your 2-year-old degu stopped moving this morning, and you are preparing to go to the emergency (after-hours) animal hospital. You keep four degus, and for the past month your child has been giving treats. In a hurry, you are about to set off with only the degu in the carrier. A family member asks whether there is anything to bring.

What is the most appropriate preparation for the visit?

1. Speed is the top priority, so put only the degu in the carrier and leave at once
2. Bring the other three cage mates as well and have all of them examined
3. Note the diet and amounts, the treats given, droppings and urine, and the number of cage mates, and bring droppings, urine, and photos of the symptoms
4. Bring the whole bag of hay and the whole bag of pellets to show the vet

AnswerC. Note the diet and amounts, the treats given, droppings and urine, and the number of cage mates, and bring droppings, urine, and photos of the symptoms

ExplanationIn an emergency the vet must narrow down the cause quickly, and information from the owner is the key to diagnosis. The correct answer is to note the diet and amounts, the type and duration of treats given, the condition of droppings and urine, any excessive drinking and urination, and the number of cage mates; collect droppings and urine if possible; and prepare photos or video of the symptoms. This takes only a few minutes, during which a warmed carrier can be readied. Leaving without information prolongs the history-taking and delays the start of treatment. Bringing the three healthy cage mates is unnecessary, adding transport stress and the risk of infection at the clinic. For the food, noting the names or photographing the bags with your phone is enough; there is no need to bring them whole.

IssuesThe owner had not organized in advance the information the vet would need in an emergency and, in a panic, nearly left without it. The owner also did not know what treats the child had been giving.

ImprovementKeep the degu's basic details (age, weight, diet, number of cage mates, medical history) in a note on your phone and keep it updated. Have the whole family record daily changes in droppings, urine, and water intake and everything given in the same log. Keep small bags and a spoon for collecting droppings and urine in the emergency kit.
