Squirrel monkey case method: 50 questions

10 a.m. in winter. A 2-year-old squirrel monkey fell from a branch in its 180 cm cage and has since been dragging its left hind leg, unable to grip branches, sitting still on the floor. For the past six months its diet has been mostly fruit, and the UVB lamp has not been replaced in the two years since purchase. It cries and resists when touched.

What is the most appropriate first action?

1. Remove the branches, move it to a low cage to rest, and get an X-ray at the vet the same day
2. Straighten the leg yourself to check for a fracture and splint it with chopsticks
3. Give extra calcium supplement and watch for a few days
4. Pick it up, put it back on the branch, and see whether it can climb again

AnswerA. Remove the branches, move it to a low cage to rest, and get an X-ray at the vet the same day

ExplanationGiven the fruit-heavy diet and worn-out UVB lamp, metabolic bone disease has likely weakened the bones and the fall caused a fracture. When a monkey drags a leg after a fall, remove the branches, rest it in a low cage it cannot fall from, and get an X-ray at the vet the same day. Straightening the leg or splinting it yourself is unnecessary and dangerous: the monkey struggles, the fracture worsens, and you get bitten. Adding calcium alone will not heal an existing fracture; the diet and UVB that caused it must be corrected. Returning it to the branch invites another fall. See a vet the same day; if it cannot move at all after the fall, go now.

IssuesA fruit-heavy diet and an unreplaced UVB lamp caused prolonged vitamin D3 and calcium deficiency. It had probably been falling from branches before the limping began, and the lack of weight and activity records delayed detection.

ImprovementReturn the staple diet to primate pellets with vitamin D3 and limit fruit to a small side food. Replace the UVB lamp every 6–12 months and check its mounting distance. Put thick bedding on the floor to soften falls. Make weekly weighing and watching how it grips branches a habit.

A September evening. For the past week an 8-year-old squirrel monkey has nearly emptied its water bottle every day, and the urine stains on the pet sheets are more than double what they were. Its weight has risen from 900 g to 1.1 kg in a year, and it gets banana and grapes as daily treats. It has an appetite and seems lively.

What is the most appropriate response?

1. It is just drinking because of the heat, so add another water bottle and watch
2. It is overweight, so halve its food and restrict water too
3. Look up causes of increased urination online and ask at next month's checkup
4. Record the excessive drinking, urination and weight gain, and have blood sugar and urine tests done at the vet within a few days

AnswerD. Record the excessive drinking, urination and weight gain, and have blood sugar and urine tests done at the vet within a few days

ExplanationExcessive drinking and urination, weight gain, and daily sweet fruit are the classic combination for diabetes and obesity, both common in squirrel monkeys; left untreated they lead to cataracts and infections. Even if it seems lively, see the vet within a few days for blood sugar and urine tests. Blaming the heat delays diagnosis. Suddenly halving food or restricting water risks low blood sugar and dehydration; change the diet only after diagnosis, with the vet. Waiting until next month lets the disease progress. Changes in drinking and urine are signs of illness, so record them and report them at the visit.

IssuesSweet fruit was given as a daily treat and a year of weight gain went unaddressed. Changes in drinking and urine output are signs of illness but are easily dismissed early on. There was no habit of recording weight.

ImprovementKeep fruit to a small side food and base the diet on pellets, vegetables and insects. Weigh weekly and check water intake daily using the bottle's scale. Increase energy use with exercise time and foraging puzzles, and have blood tests done once a year.

A spring morning. A 12-year-old squirrel monkey's right cheek is swollen, with heavy drooling and strong bad breath. It eats soft fruit but drops pellets and crickets from its mouth. Its teeth are brown and it has never had an oral exam. It turns its face away when touched.

What is the appropriate response?

1. Since it will not eat hard pellets, switch to soft food and wait for the swelling to go down
2. Apply human mouth-ulcer medicine to the cheek and watch
3. Suspect periodontal disease or a tooth-root abscess and get an oral exam and treatment at the vet the same day
4. Press the swollen area with your fingers to squeeze out the pus

AnswerC. Suspect periodontal disease or a tooth-root abscess and get an oral exam and treatment at the vet the same day

ExplanationBad breath, drooling, facial swelling and avoiding hard food are the classic signs of periodontal disease, common in squirrel monkeys, progressing to a tooth-root abscess. An abscess does not heal on its own; the monkey stops eating, weakens, and the infection spreads, so see the vet the same day for an oral exam and treatment such as tartar removal or extraction. Switching to soft food and waiting leaves the source of pain in place and makes it worse. Human medicine must not be used because of poisoning and ingestion risks. Squeezing the pus yourself gets you bitten and spreads the infection. A yearly oral exam and tartar removal are the basis of prevention.

IssuesNo oral exam in 12 years; tartar had built up by the time the teeth turned brown. Hard pellets, insects and branch-chewing were likely lacking, so the teeth were never cleaned naturally.

ImprovementHave an oral exam and tartar removal once a year at a clinic that sees primates. Give hard pellets, live insects and branches to chew every day. Check for bad breath, drooling and dropped food at every feeding as early signs.

9 p.m. during the rainy season. Since yesterday a 3-year-old squirrel monkey has passed soft stool with mucus more than five times a day. Today it is eating less and sitting still on a branch, farther from its troop mates than usual. A new monkey was brought in just two weeks ago and has not yet had a fecal exam.

What is the most appropriate response?

1. Bag and photograph the stool, keep it warm with water available, and get a fecal exam by the next day
2. Give a small dose of human anti-diarrheal and wait for it to stop
3. Withhold food to rest the gut and see a vet if it continues after 3 days
4. The diarrhea is from the change in environment, so leave it until it settles

AnswerA. Bag and photograph the stool, keep it warm with water available, and get a fecal exam by the next day

ExplanationTwo days of mucus stool with reduced appetite and withdrawal from the troop point to intestinal parasites or bacterial enteritis. The recent arrival of a new monkey without a fecal exam supports this. Bag the stool, photograph it, keep the monkey warm with water available, and see the vet for a fecal exam the same or next day. Bloody stool or lethargy means an immediate visit, even at night. Human anti-diarrheals are wrongly dosed for a small primate and, in infectious diarrhea, trap the pathogen in the gut and make things worse. A small body quickly develops low blood sugar when fasted, so waiting 3 days is dangerous. Blaming the environment and doing nothing is equally dangerous.

IssuesThe new monkey was added to the troop without an intake fecal exam, possibly bringing in parasites or bacteria. Reduced appetite and withdrawal from the troop were clear warning signs but were easy to overlook.

ImprovementGive every new monkey a fecal exam at intake and quarantine it in a separate cage until results are back. Run fecal exams on all animals twice a year. Remove droppings from the floor daily, record stool condition daily, and set a rule to see the vet if abnormalities last 2 days.

7 a.m. in January. The owner has had a cold for three days and has been doing the care without a mask. This morning a 5-year-old squirrel monkey is sneezing and coughing, has a runny nose, and is breathing faster than usual. It barely touches its food. The room is 20°C and the heater was switched off overnight.

What is the most appropriate first action?

1. Crush your own cold medicine and mix it into the food
2. Raise the room to 22–28°C, keep it humid, rest the monkey, and see the vet the same day
3. Wait and see, and go to the vet if it has not improved in a week
4. Put a basin of hot water in the cage so it can breathe the steam

AnswerB. Raise the room to 22–28°C, keep it humid, rest the monkey, and see the vet the same day

ExplanationSquirrel monkeys catch human colds, and respiratory infections progress rapidly to pneumonia. The owner's cold and the cold night are both present, and coughing, runny nose, rapid breathing and reduced appetite meet the same-day-visit criteria. First raise the room to 22–28°C, keep humidity at 50–70%, rest the monkey, and see the vet the same day. Open-mouth breathing means go now. Human cold medicine has the wrong ingredients and dose and can poison it. Waiting a week risks death from pneumonia. Hot water in the cage leads to scalds or drowning.

IssuesThe owner did the care while sick without a mask or handwashing and probably passed on the cold. The heater was switched off at night in winter, letting the room drop to 20°C; the temperature swing and cold lowered immunity.

ImprovementWhen unwell, always wear a mask and wash hands, and if possible have a healthy family member do the care. In winter keep the room above 22°C around the clock with a panel heater and check the thermometer morning and evening. Decide in advance that coughing or sneezing means a same-day vet visit.

An autumn evening. A 4-year-old squirrel monkey kept alone has been biting the base of its tail for two weeks; the hair is gone and the skin is red. It paces the same route back and forth in the cage for hours. Work has been busy, and free-roam time has dropped to once or twice a week.

What is the most appropriate response?

1. Scold it loudly every time it bites to make it stop
2. Spray a bitter-tasting spray on the tail and watch
3. See a vet for the skin, increase exercise time and foraging puzzles, and look into providing companions or social contact
4. It is just bored, so leave the TV on

AnswerC. See a vet for the skin, increase exercise time and foraging puzzles, and look into providing companions or social contact

ExplanationTail-biting, hair loss and repetitive pacing (stereotypic behavior) are classic stress-related self-injury from solitary keeping and lack of exercise. Since the skin is already red, see the vet within a few days to prevent wound infection, and at the same time fix the root cause: the environment. It needs 2–3 hours of exercise daily, foraging puzzles with hidden food, and if possible companions of its own species or interaction with the owner. Scolding adds fear and excitement, increasing stress and worsening the self-injury. Bitter spray only suppresses the behavior while leaving the cause, and the self-injury shifts elsewhere. A TV is no substitute for troop mates.

IssuesA troop-living animal was kept alone, and exercise had fallen to once or twice a week. For a species that lives in troops of dozens, solitary keeping is itself a major stressor. The early stage of stereotypic behavior was missed.

ImprovementProvide 2–3 hours of free-roam time daily and hide food to make it forage. Add foraging play such as live crickets. Rotate ropes and hammocks regularly for variety. Discuss adding a companion of the same species with the vet, and check for hair loss and stereotypic behavior daily.

6 a.m. in February. The panel heater's plug came out overnight and the room dropped to 14°C. A 6-year-old squirrel monkey is lying on the cage floor instead of in the nest box, cold to the touch, and its eyes move faintly when its name is called. Yesterday its appetite was poor and it ate almost no dinner.

What is the most appropriate first action?

1. Warm it with a cloth-wrapped hand warmer and towel, dab sugar water on the corner of its mouth if conscious, and go to the vet right away
2. Blow a hair dryer directly on it to warm it up quickly
3. Soak it in lukewarm water to warm it, then feed it
4. Put it back in the nest box, cover with a blanket, and watch until noon

AnswerA. Warm it with a cloth-wrapped hand warmer and towel, dab sugar water on the corner of its mouth if conscious, and go to the vet right away

ExplanationA squirrel monkey, for which below 18°C is dangerous, has spent a night at 14°C without eating since the day before, so it has both hypothermia and low blood sugar. Warm it gently with a hand warmer wrapped in a towel or cloth, dab sugar water on the corner of its mouth if conscious to counter the low blood sugar, and go straight to the vet. A hair dryer causes burns and shock from a sudden temperature change. Soaking in water draws even more heat from the wet body, and a barely conscious animal may drown. Watching until noon carries a high risk of death without body temperature recovering. Keep it warm during transport in a darkened carrier with a cloth-wrapped hand warmer.

IssuesThe unplugged heater was not noticed before bed and there was no temperature monitoring. The previous day's poor appetite was missed, and the monkey went into the night at high risk of low blood sugar.

ImprovementPut a max-min thermometer on the cage and check it before bed and on waking. Secure the heater plug so it cannot come loose and keep a backup heat source. On any day with poor appetite, raise the night temperature and plan a vet visit the next morning.

An early-summer afternoon. A 1.5-year-old squirrel monkey has recently developed a rounded back, cannot grip branches firmly, and falls more often. Its limb joints look thick. It has been indoors since it was acquired with no UVB lamp installed. Its diet has been mainly fruit and yogurt.

What is the appropriate response?

1. Take it out to the balcony every day for direct sunlight
2. Increase the yogurt for calcium and watch
3. Give a human vitamin D tablet every day
4. Suspect metabolic bone disease, see the vet within a few days, switch to D3 pellets and install a UVB lamp

AnswerD. Suspect metabolic bone disease, see the vet within a few days, switch to D3 pellets and install a UVB lamp

ExplanationA curved spine, thick joints, inability to grip branches and falls are metabolic bone disease itself, caused by vitamin D3 and calcium deficiency, and in a growing animal the bones keep deforming. See the vet within a few days for X-rays and blood tests, and under the vet's direction make primate pellets with D3 the staple diet and install a UVB lamp. While the bones are fragile, lower the branches to prevent falls. A balcony carries escape, bird-of-prey and crow risks; never take it outdoors. Dairy is a forbidden food and causes diarrhea. Human vitamin D tablets are far too strong and risk overdose.

IssuesIndoor keeping without a UVB lamp and an inappropriate staple diet of fruit and yogurt continued for over a year. Dairy is a forbidden food, and the basic rule of pellets as the staple was not followed. Bone problems are hard to notice early, so detection was delayed.

ImprovementMake primate pellets with vitamin D3 the staple and stop giving dairy. Install a UVB lamp and replace it every 6–12 months. Lower the branches and put thick bedding on the floor until the bones recover. Use calcium supplements as directed by the vet and monitor progress with regular X-rays.

A winter night. For three days an 18-year-old squirrel monkey has been dropping food from its mouth and eating less than half as much. It has lost 100 g in two weeks. It is sluggish and tends to stay in the nest box during the day. Its breath is not especially bad.

What is the appropriate response?

1. Loss of appetite is natural at its age, so just give the fruit it likes
2. If there is a day it has eaten almost nothing for 24 hours, see the vet the same day and report its weight history and diet
3. Force its mouth open and push pellets in
4. Try a different food for a month and see the vet if there is no improvement

AnswerB. If there is a day it has eaten almost nothing for 24 hours, see the vet the same day and report its weight history and diet

ExplanationDropping food, eating less, weight loss and sluggishness are signs of several illnesses including dental problems, enteritis and metabolic disease, and losing 100 g in two weeks in a body of around 1 kg is roughly 10%, which is serious. Not eating for 24 hours means a same-day visit; otherwise see the vet within a few days and report the weight history and diet record. Giving only fruit because of age unbalances nutrition and worsens diabetes. Forcing the mouth open gets you bitten and risks aspiration. Waiting a month lets it weaken. Elderly animals have little reserve, so early visits are the rule.

IssuesThere was a tendency to put an elderly monkey's reduced appetite down to aging. The owner had noticed three days of reduced eating and two weeks of weight loss but had no criteria for a vet visit. Checking inside the mouth is difficult, and owners cannot identify the cause themselves.

ImprovementWeigh elderly animals weekly and set a rule to see the vet at a 10% loss. Have an oral exam and blood tests at a yearly checkup. Agree as a family that 24 hours without eating means a same-day visit, and find a clinic that sees primates in advance.

1 a.m. on a Saturday night. A 7-year-old squirrel monkey has vomited three times since evening and is now passing dark-red bloody watery stool; it has come down from the branches and is lying on the floor. Its eyes are open but it barely responds to its name. The regular vet is closed and the owner has not looked up an after-hours clinic that sees primates.

What is the most appropriate response?

1. Bag and photograph the stool and vomit, keep it warm, call an emergency (after-hours) animal hospital and go now
2. Wait for the regular vet to open in the morning, giving only water in the meantime
3. Bloody stool looks alarming but is common in small animals, so look it up online and decide
4. Assume it was bad food and force it to vomit to empty the stomach

AnswerA. Bag and photograph the stool and vomit, keep it warm, call an emergency (after-hours) animal hospital and go now

ExplanationBloody, watery stool with lethargy is an emergency requiring an immediate vet visit. In bacterial or hemorrhagic enteritis, dehydration and shock progress rapidly, and waiting until morning can be fatal. Bag and photograph the stool and vomit, keep the monkey warm with a cloth-wrapped hand warmer in a dark carrier, call an emergency (after-hours) animal hospital and go. Waiting until morning is dangerous, and water alone cannot replace lost electrolytes. Deciding from online information wastes time. Forcing vomiting risks aspiration, strains the gut, and worsens gastrointestinal bleeding.

IssuesNo clinic that sees primates at night or on holidays had been identified in advance, so the emergency began with a search. Seeing a vet at the time of the evening vomiting might have prevented the late-night deterioration.

ImprovementPost the contact details of a clinic that sees primates and an emergency (after-hours) hospital next to the cage. Decide that repeated vomiting means a vet visit. Prepare an emergency kit with carrier, hand warmers, towels and stool bags in one place, and make sure the car can be kept above 22°C.

An autumn morning. The owner notices that the centers of both eyes of a 10-year-old squirrel monkey have turned cloudy white. Lately it misjudges distances when jumping between branches and falls, and takes a long time to find its food dish. Its water intake has risen over the past few months and its weight is over 1.2 kg.

What is the most appropriate response?

1. Choose a human eye drop and apply it daily
2. It is only cataracts, so add more branches so it can get by without sight
3. Suspect diabetic cataracts, see the vet within a few days for blood sugar tests, and make the environment safe
4. It is just aging, so leave it and watch

AnswerC. Suspect diabetic cataracts, see the vet within a few days for blood sugar tests, and make the environment safe

ExplanationCataracts can occur with aging alone, but combined with increased drinking and weight gain, diabetes, common in squirrel monkeys, is the likely underlying cause. See the vet within a few days for blood sugar and urine tests and an eye exam, and start dietary management if diabetes is confirmed. At the same time, prevent falls in an animal with failing sight: lower the branches, put thick bedding on the floor, and keep food and water stations in fixed positions. Human eye drops have unknown effects and can do harm. Treating it as only an eye problem and adding branches increases falls. Dismissing it as aging lets diabetes progress to infections and kidney damage.

IssuesSigns of diabetes, increased drinking and weight gain, had been present for months, but no vet visit was made until the eyes clouded. Falls from poor sight were treated as chance. The diet was not reviewed even when weight exceeded 1.2 kg.

ImprovementRecord water intake and weight weekly and see the vet when they exceed the limit. Stop fruit and sweets; base the diet on pellets, vegetables and insects. For an animal with poor sight, keep branches and feeding spots in place and use bedding that softens falls. Check blood sugar with a yearly blood test.

3 p.m. in summer. Of four monkeys, only a 3-year-old female has stayed away from the troop since morning, sitting still in a corner of a shelf. She did not come to the branches at feeding time; she turns her face when called but moves only slowly. No stool or vomit has been seen. The other three are active and well.

What is the appropriate response?

1. The others are fine, so she is not sick, just in a bad mood
2. Playing with her lively troop mates will stimulate recovery, so force her to rejoin the troop
3. Sitting apart from the troop is a sign of illness, so check her food intake and stool and consider a vet visit the same day
4. Give her a commercial energy drink for when she is listless

AnswerC. Sitting apart from the troop is a sign of illness, so check her food intake and stool and consider a vet visit the same day

ExplanationA troop-living squirrel monkey sitting still apart from its companions is at the top of the checklist of signs of illness. Troop animals hide weakness, so noticing the problem at this stage is critical. Check food intake, stool, water intake and any bite wounds, and consider a same-day vet visit. Not eating for 24 hours means a same-day visit. Blaming her mood misses early enteritis or infection. Forcing her back into the troop exposes a weakened animal to attacks in rank disputes. Human energy drinks are high in caffeine and sugar and are dangerous.

IssuesWith several animals, attention goes to the lively ones and changes in one are easily missed. Food intake and stool were not recorded per animal, so it was impossible to tell when the problem began. Judgments were being made based on the troop's behavior as a whole.

ImprovementKeep a simple daily record of each animal's food intake, stool and activity. Check at every feeding that all animals come to the branches. Keep a spare cage so a sick animal can be observed separately, and decide on a clinic that sees primates.

A winter afternoon during free-roam time. A 3-year-old squirrel monkey climbed onto the ceiling light; the cover came off and it fell 2.5 m onto the wooden floor. It cried right after the fall but now lies on its side without moving, breathing fast. Its right front leg looks bent at an unnatural angle.

What is the most appropriate first action?

1. Straighten the bent leg, splint it with chopsticks, then head to the vet
2. Pick it up and shake it to check for a response
3. Without handling it, gently move it into a dark box lined with a towel, keep it warm, and go to the vet now
4. Leave it on the floor for 30 minutes to see whether it can move

AnswerC. Without handling it, gently move it into a dark box lined with a towel, keep it warm, and go to the vet now

ExplanationBeing unable to move after a fall from height suggests head or internal injuries in addition to fractures, and is an emergency requiring an immediate vet visit. Do not handle it unnecessarily; gently move it into a dark box or carrier lined with a towel, keep it warm with a cloth-wrapped hand warmer, and head to the vet. No splint is needed, and straightening the leg makes it struggle in pain, worsening the fracture and getting you bitten. Shaking the body spreads spinal or internal damage. Watching for 30 minutes lets internal bleeding and shock progress. During transport keep the car above 22°C, and bringing a companion along helps calm it.

IssuesThe light fixture cover was not secured before free-roam time and there was no cushion at the landing spot. Despite knowing its habit of climbing high, the owner looked away for a while. No procedure or transport box had been prepared for falls.

ImprovementIn the free-roam room, cover light fixtures, fans and curtain rails and place cushions at likely landing spots. Never take your eyes off it during free-roam time. Keep a carrier that can be darkened, towels and hand warmers in the room, and agree as a family that not moving after a fall means an immediate vet visit.

A spring evening. Right after a newly acquired 2-year-old male was put into the same cage as the resident troop, the resident male chased it and bit its right arm, which is bleeding. The newcomer trembles in a corner while the resident male is still threatening and trying to approach. The wound is about 1 cm and keeps oozing blood.

What is the most appropriate first action?

1. Scold the resident male, keep both in the same cage, and wait for the hierarchy to settle
2. Isolate the newcomer in a separate cage, rinse the wound under running water, press with gauze, and see the vet the same day
3. Apply a human ointment to the wound and continue cohabitation
4. Hold the newcomer to calm it until the bleeding stops

AnswerB. Isolate the newcomer in a separate cage, rinse the wound under running water, press with gauze, and see the vet the same day

ExplanationWith bite wounds from rank disputes, the first priority is separating the victim from the attacker to prevent another attack. Move the newcomer to a separate cage, rinse the wound under running water, then press with clean gauze for 5+ minutes. Monkey bites easily become infected, so bleeding or swelling means a same-day vet visit. Keeping them together and scolding leads the excited resident male to attack again, causing deep wounds or death. Human ointments may be licked and swallowed and do not prevent wound infection. Holding a trembling animal bare-handed risks a fear bite to the owner. The rule for introductions is adjacent separate cages and a gradual process.

IssuesThe newcomer was put straight into the same cage with no quarantine or gradual introduction. There was only one hide and one feeding spot, so no escape route. No isolation cage or gauze had been prepared for bites.

ImprovementAfter quarantine, let the newcomer meet the troop through an adjacent separate cage for several weeks, then progress gradually from short shared sessions. Provide multiple hides and feeding spots. Keep gauze and an isolation cage on hand, and decide that bleeding or swelling from a bite means a same-day vet visit.

A winter night during free-roam time. There was a snapping sound, and a 5-year-old squirrel monkey is lying beside an extension cord. The cord's insulation has been chewed through and copper wire is exposed; the monkey's mouth is white and scorched. It is still touching the cord and its body is twitching slightly.

What is the most appropriate first action?

1. Immediately pick up the monkey by hand and pull it away from the cord
2. First cut the power at the outlet, then move the monkey away, check its breathing, and go to the vet now
3. Press ice directly on the burn around the mouth
4. Throw water on it to bring it round

AnswerB. First cut the power at the outlet, then move the monkey away, check its breathing, and go to the vet now

ExplanationTouching an animal that is being electrocuted with bare hands electrocutes you too, so always unplug the cord or trip the breaker first. After cutting the power, move the monkey away and check breathing and heartbeat. If it is not breathing, clear the mouth and start chest compressions, calling the vet as you continue. Electric shock causes not only mouth burns but pulmonary edema and arrhythmias hours later, so go to the vet now even if it looks mild. Cool mouth burns with a cold wet towel; ice applied directly damages tissue. Throwing water increases the risk of shock and causes hypothermia. Covering all cords or putting them in cable boxes is the basis of prevention.

IssuesFree-roam time was allowed with an uncovered extension cord. Despite knowing its habit of mouthing and chewing everything, cord management was lax. The owner did not know to cut the power first in an electric shock.

ImprovementCover every cord in the free-roam room or put it in a cable box, and put away unused cords. Put guards on heaters. Know where the breaker is, and share with the family the rule of cutting the power before touching in an electric shock.

During morning feeding. The owner closed the cage door in a hurry and the tip of a 6-year-old squirrel monkey's tail got caught; blood is coming through the gap in the wire. The last 5 cm or so of the tail hangs limp, and the monkey is crying in the cage and dragging its tail.

What is the appropriate response?

1. Hold the tail and bend it to check whether the tip is broken
2. Press the bleeding spot with gauze to stop it, and since the tail hangs limp, see the vet the same day
3. Tails heal on their own, so apply antiseptic and watch
4. The limp part is useless, so cut it off yourself

AnswerB. Press the bleeding spot with gauze to stop it, and since the tail hangs limp, see the vet the same day

ExplanationFor bleeding from a trapped tail, the basic step is to press with clean gauze for 5+ minutes without lifting it to check. If the tail tip hangs limp or is bent, a fracture or nerve damage is possible, so see the vet the same day. If necrosis sets in, amputation becomes necessary and infection is likely. Holding and bending the tail makes it struggle in pain, worsening the fracture and getting you bitten. Antiseptic alone does not treat a fracture or necrosis. Cutting it off yourself causes heavy bleeding and infection and is serious abuse. A squirrel monkey's tail is not prehensile but is important for balance; leave treatment to the vet.

IssuesClosing the door in a hurry meant the tail position was not checked. There was no time margin for feeding and door handling had become careless. The habit of closing cage doors slowly had not taken hold.

ImprovementAlways check where the tail and fingers are when opening or closing doors, and close slowly. Feed at a time when you are not rushed. Keep gauze and pressure dressings on hand, and decide that a limp or bent tail means a same-day vet visit. Review door and drawer trapping risks at the same time.

A December night. The cover has come off the panel heater inside the cage, and a 2-year-old squirrel monkey is walking without putting its soles on the floor; on inspection both soles are red with blisters in places. The heater surface is hot to the touch.

What is the most appropriate first action?

1. Turn off the heater, cool the feet with a cold wet towel, and see the vet the same day
2. Pop the blisters with a needle to let the fluid out
3. Apply aloe or a human burn ointment
4. They are only red, so skip cooling, put the cover back on the heater and watch

AnswerA. Turn off the heater, cool the feet with a cold wet towel, and see the vet the same day

ExplanationRedness and blisters on the soles are low-to-moderate burns from the heater. First turn off the heat source, cool the area with a cold wet towel, and see the vet the same day. The soles are used for walking, so infection or ulceration means lengthy treatment. Popping blisters opens a route for infection. Human ointments or aloe may be licked and swallowed, and their ingredients can irritate and worsen the burn. Watching without cooling lets the heat linger deep in the skin and spread the damage. While cooling, keep the room above 22°C so the whole body does not get too cold.

IssuesThe owner failed to notice the heater cover had come off and neglected inspections. Squirrel monkeys touch and climb everything, so direct access to a heat source causes burns. The heater's surface temperature had not been checked.

ImprovementAlways keep the heater covered and check the cover and surface temperature every morning. If placed inside the cage, heat from outside the wire or position it where it cannot be touched. Share with the family: cool burns with a cold wet towel and see the vet.

A spring morning during free-roam time. A 4-year-old squirrel monkey leapt toward a window with the curtains open, hit the glass and fell to the floor. Its nose is bleeding, the inside of its mouth is cut, it walks unsteadily and keeps one eye closed. The fall was from about 1 m.

What is the appropriate response?

1. Plug the nose with tissue to stop the bleeding and, if it seems fine, watch for a week
2. It only bumped into something, so continue free-roam time and observe its movements
3. Pour water into its mouth to rinse the bleeding
4. Put it in a dark carrier to rest and, because of the unsteadiness and closed eye, go to the vet now

AnswerD. Put it in a dark carrier to rest and, because of the unsteadiness and closed eye, go to the vet now

ExplanationHitting glass is a strong blow to the head; nosebleed and mouth bleeding together with unsteadiness and a closed eye suggest brain injury, eye trauma or facial fractures. Keep it quiet in a dark carrier and go to the vet now. Plugging the nose with tissue obstructs breathing, and head-injury symptoms can worsen hours later, so waiting a week is dangerous. Continuing free-roam time invites another collision or fall. Pouring water into the mouth causes aspiration. Prevention: mark window glass with curtains or film so it is visible, and keep windows closed and covered during free-roam time.

IssuesThe curtains were left open during free-roam time, and a monkey that cannot perceive glass tried to leap outside. The dual risk of windows, escape and collision, was underestimated. The owner did not know the signs of head injury.

ImprovementClose windows during free-roam time and cover the glass with curtains or film. Cover lights, fans and mirrors the same way. Remember that unsteadiness, a closed eye or vomiting are head-injury signs requiring an immediate visit, and keep a carrier that can be darkened in the room.

A summer morning. A rope in the cage had frayed, and a 3-year-old squirrel monkey was found hanging with two fingers of its left hand tangled in the fibers. The owner untangled and freed it, but the fingers are swollen purple and it cannot close its hand. How long the blood flow was cut off is unknown; it may have been several hours at least.

What is the most appropriate response?

1. The swelling will go down once blood flow returns, so warm and massage it and watch
2. Cool the swollen fingers and, because necrosis or fracture is possible, see the vet the same day
3. Wrap a human anti-inflammatory patch around the fingers to reduce swelling
4. It can live without those fingers, so just remove the rope and leave it at that

AnswerB. Cool the swollen fingers and, because necrosis or fracture is possible, see the vet the same day

ExplanationFingers deprived of blood flow for a long time, swollen purple, may have necrosis, fractures or ligament damage; see the vet the same day for assessment. Advancing necrosis requires amputation and infection worsens the whole body. Until transport, cool lightly and rest. Warming and massaging can spread toxins from necrotic tissue through the body and worsen any fracture. Human patches can be licked, causing poisoning, and are unsuitable for tiny fingers. Removing the rope is correct prevention but no reason to skip the vet. Frayed ropes and thin fibers cause finger and tail entanglement, so inspect them daily.

IssuesThe frayed rope had been left without inspection. There was no habit of checking the cage at night, so the entanglement lasted for hours. Cage toys were checked for safety only when introduced and never reviewed afterward.

ImprovementCheck ropes and hammocks daily for fraying and looseness, and replace anything with loose fibers immediately. Inspect toys when rotating them. Visually check the cage before bed and on waking, and decide that swollen or discolored fingers or tail mean a same-day vet visit.

An autumn evening. Loud screaming comes from a cage of five monkeys; on rushing over, a 4-year-old male's left ear is torn and dripping blood. The others have settled, but that male trembles in a corner while another male is still glaring at him. The wound is about 2 cm and keeps oozing blood.

What is the most appropriate first action?

1. An ear wound is not life-threatening, so leave him in the troop
2. To calm things down, scold the whole troop and bang on the cage to quiet them
3. Isolate the injured monkey, rinse the wound under running water, press with gauze, and see the vet the same day
4. Pour plenty of rubbing alcohol on the ear wound to stop the bleeding

AnswerC. Isolate the injured monkey, rinse the wound under running water, press with gauze, and see the vet the same day

ExplanationWith bite wounds, isolation comes first: move him to a separate cage away from the attacker, rinse the wound under running water, then press with clean gauze for 5+ minutes. Ears are richly supplied with blood vessels and keep bleeding, and tears often need stitches, so see the vet the same day. Left in the troop, he will be attacked again, and a weakened animal remains the target of rank disputes. Banging on the cage or scolding excites the whole troop and triggers further attacks. Alcohol causes severe pain and tissue damage, and he struggles and widens the wound. In a troop with ongoing rank disputes, multiple hides and feeding spots reduce competition and prevent injuries.

IssuesSigns of rank disputes in the troop were missed, and there may have been only one hide and one feeding spot. Rising tension between males went unnoticed. No isolation cage or gauze was prepared, so response was likely to be slow.

ImprovementProvide multiple hides, feeding and water spots, and hide food in several places. Watch the number and ranking of males, and consult the vet if chasing continues. Keep an isolation cage and gauze on hand, and share with the family the bite procedure: isolate, rinse, press, same-day vet visit.

A midsummer afternoon; a fan was left running during free-roam time. A 2-year-old squirrel monkey put its hand through a gap in the fan guard and is screaming, with a finger on its right hand bleeding. Part of the fingertip is missing and blood is dripping onto the floor. The monkey is agitated and leaping around.

What is the most appropriate first action?

1. Turn off the fan, wrap it in a towel to calm it, press with gauze for 5+ minutes, and see the vet the same day
2. Chase and catch it, wipe the wound with tissue and apply an adhesive bandage
3. Let it run free until it calms down, then look at the wound
4. Since the fingertip is missing, close the wound with superglue

AnswerA. Turn off the fan, wrap it in a towel to calm it, press with gauze for 5+ minutes, and see the vet the same day

ExplanationFirst turn off the fan to prevent further injury, and without chasing the agitated monkey, cover its body and face with a towel to darken and calm it. Press with clean gauze for 5+ minutes to stop the bleeding, without lifting it to check. A missing fingertip needs stitches and infection control, so see the vet the same day; if bleeding is heavy and will not stop, go now. Chasing excites it, increases bleeding, and gets you bitten. Tissue sticks to the wound and adhesive bandages get licked and swallowed. Letting it run free lets the bleeding continue. Superglue damages tissue and seals in infection. The rule is to turn off fans during free-roam time.

IssuesA fan was left running during free-roam time. A guard with gaps a hand can fit through is dangerous for an inquisitive squirrel monkey. The owner did not know that chasing an agitated animal makes things worse.

ImprovementTurn off the fan or remove it from the room during free-roam time, and keep the room below 28°C with air conditioning. Deal with lights, windows and cords in advance too. Keep a thick towel and gauze in the room, and decide: press bleeding for 5+ minutes, and go to the vet now if it will not stop.

A winter morning; free-roam time was allowed while a guest was visiting. A 3-year-old squirrel monkey jumped onto the table, knocked over a cup of freshly brewed coffee, and was doused with hot liquid from head to back. It is screaming and running around, its fur is wet and the skin is red. The guest is flustered.

What is the most appropriate first action?

1. Blow a hair dryer on it to dry the fur
2. Catch it and wrap it in a towel, cool the affected area with a cold wet towel, and see the vet the same day
3. The skin is only red, so it will be fine once the fur dries; just watch
4. Apply butter or olive oil to protect the skin

AnswerB. Catch it and wrap it in a towel, cool the affected area with a cold wet towel, and see the vet the same day

ExplanationWith scalds from hot liquid, heat soaked into the fur keeps damaging the skin, so first catch it with a thick towel to calm it, cool the affected area with a cold wet towel, and see the vet the same day. Extensive burns or blisters mean go now. A hair dryer worsens the burn. Even if it only looks red, blisters and skin necrosis can appear hours later, so waiting is dangerous. Oil or butter traps the heat and makes it worse, and causes diarrhea when licked. To avoid hypothermia from over-cooling, keep the rest of the body warm with a towel and the room above 22°C.

IssuesThe monkey was not returned to the cage when a guest came and free-roam time continued. A hot drink was left on the table with no thought for its habit of jumping onto tables. The rule of returning it to the cage during chores and visits was not followed.

ImprovementAlways return it to the cage during visits and chores. Keep hot drinks and pots out of the room during free-roam time. Write down the burn procedure, cool with a cold wet towel and see the vet, share it with the family, and keep a thick towel in the room.

A summer evening during free-roam time. A 4-year-old squirrel monkey opened a desk drawer and trapped a finger of its right hand when it slid shut. The owner opened the drawer to free it, but the finger is swollen bluish-purple and it cannot close its hand or grip branches. It keeps licking the finger.

What is the appropriate response?

1. Cool the finger lightly, rest it, and since it is swollen and immobile, get an X-ray at the vet the same day
2. Pull the finger straight and tape it in place
3. Licking will heal it, so put a lock on the drawer and watch
4. Warm it to improve circulation and reduce the swelling

AnswerA. Cool the finger lightly, rest it, and since it is swollen and immobile, get an X-ray at the vet the same day

ExplanationA trapped finger that is swollen and immobile may be fractured or dislocated; cool it lightly, rest it, and get an X-ray at the vet the same day. Being unable to grip branches affects every aspect of life for a tree-dwelling animal. Pulling or taping the finger worsens the fracture and gets you bitten as it struggles. A lock is correct prevention, but an already injured finger does not heal by licking; continued licking widens the wound and causes infection. Warming increases swelling and internal bleeding. Since it is smart enough to open drawers, the rule during free-roam time is to lock drawers and fix doors with stoppers.

IssuesThe owner knew it could open drawers but had not locked them. Supervision during free-roam time was insufficient to prevent the trapping. The owner did not know that letting it lick a swollen, immobile finger makes things worse.

ImprovementPut child locks on all drawers in the free-roam room and fix doors with stoppers. Close cage doors slowly. Decide that a swollen, discolored or immobile finger or tail means a same-day vet visit, and find in advance a clinic that can X-ray primates.

10 a.m. in early summer. The owner returns from shopping to find the cage door open and the screen gone from a window left slightly open for ventilation. A 5-year-old male squirrel monkey is sitting on the balcony railing looking at a neighbor's tree. His female companion is still in the cage, calling repeatedly.

What is the most appropriate first action?

1. Rush out onto the balcony and run to grab him
2. Call his name loudly and get the neighbors to help corner him
3. Do not chase; lure him with favorite food and his cage mate's calls, and wait quietly for him to return
4. Close the window and wait inside the house for him to come back on his own

AnswerC. Do not chase; lure him with favorite food and his cage mate's calls, and wait quietly for him to return

ExplanationChasing an escaped squirrel monkey startles it into fleeing farther, toward dangerous places like power lines and roads, so the rule is never to chase. Luring with a companion's calls and favorite food is most effective: bring the cage mate nearby in a carrier, place favorite food within reach, and wait quietly. Balconies also carry bird-of-prey and crow risks, and the owner staying calm raises the chance of his return. Cornering him with a crowd spreads panic and flight. Closing the window and waiting inside leaves his escape route open while time passes. Double-locking the cage and locking windows are daily basics, and contacts for escapes should be prepared.

IssuesDespite his ability to open latches, the cage had no double lock, and the owner went out with the window open behind only a screen. No escape procedure had been decided. Safety checks of the cage before going out were insufficient.

ImprovementDouble-lock the cage door, including a padlock, and check it before going out. Lock windows rather than relying on screens, and ventilate with air conditioning. Write down the escape procedure, no chasing, lure with companion calls and favorite food, plus contacts for the municipal office and police, and share it with the family.

A winter night. While walking down the hall carrying laundry, the owner stepped on a 2-year-old squirrel monkey that had come underfoot during free-roam time. It screamed and ran off, but now crouches in a corner, curled up as if holding its belly, breathing fast. Its gums look pale.

What is the most appropriate first action?

1. Without handling it, gently move it into a dark carrier, keep it warm, and go to the vet now
2. It is just in pain, so offer a favorite food and see whether it perks up
3. Feel its belly to check for fractures or internal problems yourself
4. There are no visible wounds, so watch until morning

AnswerA. Without handling it, gently move it into a dark carrier, keep it warm, and go to the vet now

ExplanationBeing stepped on can cause internal injuries, internal bleeding and rib fractures even without visible wounds. Rapid breathing and pale gums are signs of shock or internal bleeding, so go to the vet now. Do not handle it unnecessarily; gently move it into a dark carrier lined with a towel, keep it warm with a cloth-wrapped hand warmer, and transport. Favorite food does not stop internal bleeding, and feeding interferes if anesthesia or surgery is needed. Feeling the belly causes pain, gets you bitten, and worsens internal injuries. Waiting until morning carries a high risk of death from progressing shock. Checking the floor as you walk and returning it to the cage during chores prevents this accident.

IssuesThe monkey was left loose during free-roam time while the owner's view was blocked by laundry. Its habit of coming underfoot and climbing clothes was not considered, and the rule of returning it to the cage during chores was not followed.

ImprovementAlways return it to the cage during chores, visits, or when carrying things. Check the floor as you walk during free-roam time. Remember that rapid breathing, pale gums and crouching are signs for an immediate vet visit; prepare a carrier and hand warmers and post the after-hours hospital's contact details.

A winter night during free-roam time. The bathroom door was open and a 3-year-old squirrel monkey fell into a bathtub still holding leftover water. The owner heard a noise minutes later and pulled it out; it is soaked, coughing and shivering. It is breathing, but water is coming from its mouth and it is limp.

What is the most appropriate first action?

1. Hold it upside down and shake it to get the water out of its lungs
2. Blow a hair dryer on high to dry it quickly
3. Towel off the water, keep it warm with a cloth-wrapped hand warmer, watch its breathing, and go to the vet now
4. If the coughing stops it is fine, so dry it, return it to the cage, and watch until morning

AnswerC. Towel off the water, keep it warm with a cloth-wrapped hand warmer, watch its breathing, and go to the vet now

ExplanationIn near-drowning, besides water in the airway and hypothermia, pulmonary edema can develop hours later, so go to the vet now even if it is breathing. First gently wipe water from the mouth, towel off the water, and watch its breathing while keeping it warm with a cloth-wrapped hand warmer. If breathing stops, clear the mouth and start chest compressions and rescue breaths. Shaking it upside down injures the spine and causes aspiration of vomit. A hair dryer on high causes burns and sudden temperature changes. Even if the coughing stops, lung inflammation appears later, so waiting until morning is dangerous. Prevention basics: keep the bathroom door closed and drain the tub.

IssuesThe bathroom door was open during free-roam time and water was left in the tub. The roaming area was not restricted and the accident happened in the few minutes the owner looked away. Doors that should have been fixed with stoppers were not managed properly.

ImprovementKeep the free-roam room away from the bathroom, toilet and kitchen, and keep doors closed and fixed with stoppers. Always drain the bathtub. Decide that near-drowning means an immediate vet visit even if it is breathing, and keep towels and hand warmers in the room.

An autumn afternoon. A medium-sized dog brought by a guest got into the living room and barked at and chased a 4-year-old squirrel monkey during free-roam time. The monkey fled up onto the curtain rail, but the dog keeps jumping beneath it. The monkey is screaming continuously and the rail is swaying.

What is the most appropriate first action?

1. Reach up to the curtain rail to grab the monkey first
2. Take the dog out of the room and calm it, then wait for the monkey to come down on its own, lured by companion calls or favorite food
3. Let them get used to each other and just watch
4. Shout loudly at both to make them stop

AnswerB. Take the dog out of the room and calm it, then wait for the monkey to come down on its own, lured by companion calls or favorite food

ExplanationThe rule is never to keep them in the same room as dogs, cats or ferrets; here the first priority is removing the threat, the dog, from the room. Reaching suddenly for an agitated monkey gets you bitten out of fear or makes it fall from the rail and break a bone. After removing the dog, quiet the room and lure it with companion calls or favorite food, waiting for it to come down on its own. If it falls, move it to a carrier without handling it and see the vet. Watching in the hope they get used to each other stimulates the dog's prey drive and leads to a fatal bite. Shouting excites both further, inviting falls or attacks. When a guest brings a dog, return the monkey to the cage beforehand.

IssuesThe owner knew a guest was bringing a dog but had not returned the monkey to the cage. The danger of sharing space with a predator such as a dog was underestimated. The rule of returning it to the cage during visits was not followed.

ImprovementDuring visits, especially when other animals are coming, always return it to the cage beforehand and double-lock the door. Never let dogs, cats or ferrets into the monkey's room. Share with family and guests the panic procedure: do not chase, quiet the room, and lure with favorite food and companion calls.

A winter morning. A 6-year-old squirrel monkey was running along the curtain rail during free-roam time when the rail came away and it fell to the floor with it. Since the fall it does not move either hind leg and tries to crawl with only its front legs. It has leaked urine, and its hind legs respond poorly to touch.

What is the most appropriate first action?

1. Pinch the hind legs to check for a response, and if they do not move, rest it and see the vet the next day
2. Pick it up and massage the hind legs to restore circulation
3. Place it on a board or towel without twisting the body, put it in a dark carrier, and go to the vet now
4. It only leaked urine, so return it to the cage to settle down

AnswerC. Place it on a board or towel without twisting the body, put it in a dark carrier, and go to the vet now

ExplanationWhen both hind legs are immobile and urine has leaked after a fall, a spinal fracture or spinal cord injury is strongly suspected. Twisting the body spreads the damage, so lay it flat on a board or firm towel, keep it from moving, put it in a dark carrier, and go to the vet now. Being unable to move after a fall or electric shock meets the criteria for an immediate visit. Pinch tests done by an owner are not reliable, and waiting until the next day loses the chance of recovery. Picking it up and massaging injures the spinal cord further. Urine leakage is a sign of nerve damage, and returning it to the cage misses the chance for treatment. Curtain rails need measures to prevent climbing.

IssuesThe owner knew it climbed curtain rails but had not checked they were secure, and there was no cushion at the landing spot. The owner did not know how to transport after a fall or recognize the risk of spinal injury.

ImprovementCover curtain rails so they cannot be climbed, or secure them firmly. Place cushions at landing spots and never take your eyes off it during free-roam time. Remember: if it cannot move, place it on a board without twisting and go to the vet now; keep a carrier and a board-like item on hand.

A spring night. The moment a family member closed the living-room door, the tail of a 2-year-old squirrel monkey in free-roam time was caught. They opened it at once, but several cm of skin halfway along the tail has been stripped off, exposing bone, and blood is dripping. The monkey is screaming and running around dragging its tail.

What is the most appropriate first action?

1. Catch it with a towel, press the wound with gauze, press lightly on the heart side, and go to the vet now
2. Wrap a bandage tightly around the tail to stop the blood and see the vet the next day
3. Put the stripped skin back in place and stick it down with adhesive bandages
4. Tails regenerate, so disinfect it and watch

AnswerA. Catch it with a towel, press the wound with gauze, press lightly on the heart side, and go to the vet now

ExplanationA tail with skin stripped off and bone exposed carries a high risk of infection and necrosis and bleeds heavily, so go to the vet now. Do not chase the fleeing animal; catch it by wrapping it in a thick towel, press with clean gauze for 5+ minutes, and press lightly on the heart side of the tail to reduce bleeding. A tight bandage cuts off blood flow and causes necrosis, and waiting until the next day lets infection progress. Replaced skin will not take, and adhesive bandages get licked and swallowed. A squirrel monkey's tail does not regenerate. Prevention basics: check the tail's position when opening and closing doors, and fix doors with stoppers during free-roam time.

IssuesDoors were not fixed with stoppers during free-roam time, and a family member closed one without checking where the monkey was. Not everyone in the family was aware of the tail-trapping risk. No gauze or towel was ready, delaying the response.

ImprovementFix doors with stoppers during free-roam time and brief the whole family on doors and drawers. Make a habit of checking the tail and fingers before closing anything. Keep a thick towel and gauze in the room, and decide that a serious tail wound means an immediate vet visit.

A summer morning. The owner forgot to lock a window, and a 2-year-old squirrel monkey got out onto the balcony. Two crows have landed and are threatening it, and the monkey is frozen at the end of the railing, screaming. The owner spots it from inside, but stepping onto the balcony might make it jump over the railing.

What is the most appropriate first action?

1. Rush over and grab it before it falls off the railing
2. Throw things at the crows to drive them off
3. Quietly open the window and lure it from inside with favorite food and companion calls, driving the crows off with noise
4. Wait inside until the monkey comes back on its own

AnswerC. Quietly open the window and lure it from inside with favorite food and companion calls, driving the crows off with noise

ExplanationBalconies are where birds of prey and crows attack monkeys; the rule is never to let it outdoors. Rushing at an animal frozen at the end of a railing startles it into leaping off, causing a fall or escape. Quietly open the window, place favorite food on the inside, let it hear its cage mates' calls, and lure it in. Keep the crows at a distance with noise such as clapping. Throwing things excites the crows into attacking or sends the monkey leaping in panic. Just waiting inside allows the crows to attack. Once it is back, check for wounds; any bite or scratch means a same-day vet visit. Check that windows are locked every time.

IssuesA window was left unlocked, giving access to the balcony. The danger of a balcony visited by crows and birds of prey was underestimated. The rule of never chasing an escaped animal had not been learned.

ImprovementLock every window before free-roam time and add secondary locks. Install a fence the monkey cannot open in front of windows leading to the balcony. Share with the family the escape procedure, no chasing, lure with favorite food and companion calls, and decide that any injury sustained outdoors means a same-day vet visit.

Valentine's night. A 3-year-old squirrel monkey in free-roam time opened a box on the table and ate about half a chocolate bar. Thirty minutes later it is restless and leaping about, its heart is racing, and it is trembling and drooling. The owner was unconcerned, thinking it just likes sweets.

What is the most appropriate first action?

1. Give it milk to dilute the chocolate
2. Put a finger in its mouth and force it to vomit
3. It is leaping about energetically, so watch until morning
4. Check how much it ate and the packaging, call the vet, and go now

AnswerD. Check how much it ate and the packaging, call the vet, and go now

ExplanationChocolate is a forbidden food for squirrel monkeys; theobromine and caffeine cause severe poisoning in a body of around 1 kg. Excitement, rapid heartbeat, trembling and drooling are poisoning symptoms that progress to seizures and arrhythmias, so take the packaging and amount eaten, call the vet, and go now. Forcing vomiting yourself risks aspiration and esophageal injury, and you get bitten as it struggles. Milk is dairy, a forbidden food that causes diarrhea, and does not dilute the toxin. Leaping about is excitement from poisoning, not a sign of health. Human sweets and chocolate belong in locked storage.

IssuesHuman sweets were left on the table during free-roam time. Despite its ability to open drawers and boxes, storage was lax, and the owner did not know chocolate is toxic to primates. The excitement of poisoning was mistaken for liveliness.

ImprovementKeep sweets, chocolate, medicines and cigarettes in locked storage and leave nothing on the table during free-roam time. Post a list of forbidden foods on the refrigerator and share it with the family. Set the procedure for accidental ingestion: take the packaging, call the vet, and do not induce vomiting yourself.

A Sunday morning. A pill case lies on the floor and two of the owner's blood-pressure tablets are missing. A 5-year-old squirrel monkey in free-roam time was nearby, working its mouth. It has no symptoms so far, but whether it swallowed them cannot be confirmed. The regular vet is closed today.

What is the most appropriate response?

1. There are no symptoms, so wait and see if any appear
2. Check the drug's name, ingredients and dose, call a clinic open at night and on holidays for instructions, and go right away
3. Give it plenty of water to dilute the drug
4. Give it salt water to make it vomit

AnswerB. Check the drug's name, ingredients and dose, call a clinic open at night and on holidays for instructions, and go right away

ExplanationA human blood-pressure drug is an overdose for a body of around 1 kg, and low blood pressure, slow heart rate and loss of consciousness can appear hours later. Even on mere suspicion of ingestion, check the drug's name, ingredients and tablet count, call a clinic open on holidays for instructions, and go right away. Once symptoms appear, treatment is delayed; measures such as activated charcoal work best early. Waiting because there are no symptoms is dangerous. Large amounts of water do not prevent absorption, and inducing vomiting with salt water causes salt poisoning, which is fatal in a small primate. Medicines belong in locked storage, managed on the assumption that it can open pill cases.

IssuesMedicines were not in locked storage, and the pill case was within the monkey's reach. Its ability to open drawers and cases was underestimated. No contact for a clinic open on holidays had been prepared, so deciding what to do took time.

ImprovementKeep all medicines, cigarettes, batteries and small items in locked storage, and check the floor and table before free-roam time. Post next to the cage the contact details of a clinic that sees primates on holidays and at night. Share with the family the ingestion procedure: call with the drug information and do not induce vomiting yourself.

An autumn evening. A child gave a 4-year-old squirrel monkey several grasshoppers caught in a park, reasoning that it likes insects. Two hours later it has vomited twice, is drooling heavily and is unsteady. The park may have been sprayed with herbicide the day before.

What is the most appropriate response?

1. It eats insects all the time, so treat it as indigestion and watch
2. Take the vomit and the remaining insects and go to the vet now
3. Give a small amount of human stomach medicine as an anti-nausea remedy
4. Feed it the rest of the grasshoppers to fill its stomach

AnswerB. Take the vomit and the remaining insects and go to the vet now

ExplanationWild-caught insects are a forbidden food; they may carry pesticides, herbicides or parasites. Vomiting, drooling and unsteadiness are symptoms of pesticide poisoning such as organophosphates, which progresses rapidly to seizures and breathing difficulty, so take the vomit and remaining insects and go to the vet now. The safety of its usual insects and wild ones is completely different, and dismissing this as indigestion is dangerous. Human stomach medicine has the wrong ingredients and dose and delays poisoning treatment. Feeding the remaining grasshoppers increases the toxin intake. Limit insects to commercially farmed crickets and mealworms, and make clear to children which foods may be given.

IssuesThe family had not shared the list of forbidden foods, and a child gave wild insects with good intentions. The possibility of herbicide spraying had not been checked. Feeding was managed by one owner alone, with little communication to the family.

ImprovementPost a list of allowed and forbidden foods where the whole family can see it. Limit insects to commercially farmed ones and make a rule that children may not feed it without the owner's permission. Share the procedure for suspected poisoning: take the vomit and the cause and go to the vet now.

A winter morning. A 3-year-old squirrel monkey that was taking apart a clock during free-roam time yesterday has refused food since this morning, is drooling, and dislikes having its belly touched. The clock's button battery is nowhere to be found. The battery has not appeared in its stool.

What is the most appropriate response?

1. Wait for it to appear in the stool and see whether the appetite returns
2. Feed large amounts of high-fiber vegetables to pass the battery quickly
3. Suspect a swallowed battery, go to the vet now, and locate it with an X-ray
4. A battery that small is harmless, so carry on as normal

AnswerC. Suspect a swallowed battery, go to the vet now, and locate it with an X-ray

ExplanationA button battery discharges inside the digestive tract, chemically damaging the lining within hours and causing perforation. Loss of appetite, drooling and a painful belly are signs of this; with the battery unaccounted for, go to the vet now to locate it with an X-ray and remove it by endoscopy or surgery if needed. While waiting for it to pass, the esophagus or stomach is being damaged. Large amounts of vegetables will not expel the battery and only interfere with treatment. Small as it is, a battery is a serious hazard, and carrying on as normal risks death from perforation or peritonitis. Prevention: keep batteries and small items in locked storage and leave nothing that can be taken apart in the room.

IssuesA clock that could be taken apart was left in the room during free-roam time. The room was not managed on the assumption that it mouths everything and takes things apart. The owner failed to decide on a vet visit when the battery went missing.

ImprovementRemove battery-powered items, remotes and clocks from the free-roam room and keep them in locked storage. After free-roam time, check that nothing is broken. Decide that a missing small item plus loss of appetite or drooling means an immediate vet visit, and find a clinic that can take X-rays.

An early-summer night. A family member who read online that monkeys like fruit and dairy gave a 2-year-old squirrel monkey avocado and yogurt as a treat. The next morning it has passed watery stool several times, is limp, breathing fast, and will not touch its food.

What is the most appropriate response?

1. Watery stool with lethargy and rapid breathing: report what was fed and go to the vet now
2. Dairy diarrhea is temporary, so stop the yogurt and watch
3. Give more yogurt to settle the gut
4. Give half a dose of a human anti-diarrheal

AnswerA. Watery stool with lethargy and rapid breathing: report what was fed and go to the vet now

ExplanationAvocado and dairy are both forbidden foods for squirrel monkeys. Compounds in avocado affect the heart and breathing, and dairy causes diarrhea. Watery stool with lethargy and rapid breathing meets the criteria for an immediate vet visit. Report what was fed and how much, and bring stool photos. Assuming it is only dairy diarrhea and watching misses breathing difficulty from avocado poisoning. More yogurt worsens the diarrhea. Human anti-diarrheals are wrongly dosed and trap toxins in the gut. The problem was a family member deciding on food from online information alone; the forbidden-food list must be shared.

IssuesA family member fed avocado and dairy, both forbidden foods, based on online information. Someone other than the owner made feeding decisions independently, and the forbidden-food list was not shared with the family. Poisoning symptoms could not be distinguished from simple diarrhea.

ImprovementPost the forbidden-food list on the refrigerator or feeding area and make a rule that no family member gives treats on their own. Limit side foods to vegetables, insects, boiled egg and a little fruit. Decide that lethargy, rapid breathing or watery stool means an immediate vet visit, and keep records so you can report what was fed.

2 p.m. in August, 36°C outside. A power outage has stopped the air conditioning, and the closed room has risen to 33°C in an hour. Three squirrel monkeys are on the branches breathing shallowly and rapidly with their mouths open, moving sluggishly and not going to the water. There is no word on when power will be restored.

What is the most appropriate first action?

1. Pour cold water over them to cool their whole bodies at once
2. Open windows and make shade, place frozen water bottles wrapped in cloth, get them to drink, and go to the vet now if symptoms persist
3. Darken the room and wait quietly until power is restored
4. Immerse them in ice water to lower body temperature

AnswerB. Open windows and make shade, place frozen water bottles wrapped in cloth, get them to drink, and go to the vet now if symptoms persist

ExplanationThe right temperature for squirrel monkeys is 22–28°C; open-mouth breathing at 33°C is an early sign of heatstroke. First create airflow and shade, place frozen water bottles or ice packs wrapped in cloth in the cage to cool gradually, and make water available. If there is no improvement, or consciousness is dulled, cool the car and go to the vet now. Cooling rapidly with cold or ice water constricts blood vessels, traps heat, and causes shock. Just waiting for power lets body temperature keep rising. Prepare for summer outages with ice packs, batteries for a fan, and an evacuation destination.

IssuesThere was no preparation for a summer power outage, and the closed room heated up rapidly. There was no habit of checking the thermometer and acting early, so the problem went unnoticed until open-mouth breathing appeared. No evacuation destination had been considered.

ImprovementKeep ice packs and frozen water bottles in the freezer and have a battery-powered fan ready. Monitor room temperature with a max-min thermometer and act when it exceeds 30°C. Decide on an evacuation destination for prolonged outages (car, relatives' home, etc.) and be ready to move them in carriers.

Late on a winter night, a strong earthquake (JMA intensity 5+). A bookshelf has toppled against the cage, which is tilted, and branches have fallen. The two squirrel monkeys inside are screaming continuously, and one is nearly pinned under a branch. Aftershocks continue and the room lights are out.

What is the most appropriate first action?

1. Secure your own safety first, check the situation with a flashlight, right the cage, remove the fallen branches, and check for injuries
2. Aftershocks are frightening, so open the cage door and let the two run free
3. Reach into the cage in the dark and quickly pull the two out
4. Stay well away until the aftershocks stop and wait until morning

AnswerA. Secure your own safety first, check the situation with a flashlight, right the cage, remove the fallen branches, and check for injuries

ExplanationIn a disaster, the owner's own safety comes first: get footwear and a flashlight before approaching. Right the cage, remove the fallen branches, and check the pinned animal for bleeding or limping. Move any animal that cannot move into a dark carrier and see the vet once the aftershocks settle. Opening the door and letting them loose leads to injuries among broken glass and fallen objects, and risks escape. Reaching into the cage in the dark among panicking animals gets you bitten and excites them further. Leaving them until morning risks the pinned animal dying from compression or hypothermia. Preparation: anchor the cage to the wall and keep furniture that could topple away from it.

IssuesAn unsecured bookshelf stood near the cage and fell directly onto it in the earthquake. The cage itself was not anchored, and the branches were poorly secured. There was no disaster kit such as a flashlight or carrier for a power outage.

ImprovementAnchor the cage to the wall and keep furniture that could topple away from it. Secure branches and shelves firmly. Keep a disaster kit next to the cage: flashlight, carrier, hand warmers, and several days of pellets. Check in advance whether shelters accept animals and decide how to transport primates.

11 p.m. in January. Heavy snow has caused a power outage, stopping the panel heater and air conditioning. The room dropped to 17°C in an hour, and the three squirrel monkeys are huddled together shivering in the nest box. Restoration is not expected before morning. A portable gas stove, a hot-water bottle and disposable hand warmers are available.

What is the most appropriate first action?

1. Leave the portable gas stove burning in the room to raise the temperature
2. Put the hot-water bottle and towel-wrapped hand warmers in the nest box, cover the whole cage with a blanket, and check the temperature until morning
3. Put disposable hand warmers unwrapped into the nest box and have all the monkeys press against them
4. Take all three into the bed to sleep with the humans

AnswerB. Put the hot-water bottle and towel-wrapped hand warmers in the nest box, cover the whole cage with a blanket, and check the temperature until morning

ExplanationBelow 18°C is dangerous for squirrel monkeys; left alone, hypothermia and low blood sugar progress. Put the hot-water bottle and towel-wrapped disposable hand warmers near the nest box, cover the whole cage with a blanket to hold in heat, and check the thermometer regularly until morning. Their habit of huddling together also helps conserve warmth. A portable gas stove in a closed room causes carbon monoxide poisoning, killing people and monkeys alike, plus fire risk. Unwrapped hand warmers cause low-temperature burns. Taking them into bed risks crushing them when you roll over, plus escape and infections from humans such as herpes.

IssuesNo alternative heat source had been prepared for a winter outage, leading to consideration of dangerous heating methods. Room temperature was monitored with a max-min thermometer, but no storage place had been set for blankets and hand warmers in case of an outage.

ImprovementIn winter keep battery-free heat sources (hot-water bottle, disposable hand warmers, blankets, insulating sheets) in a disaster kit, and learn to always wrap hand warmers in cloth. Never use a portable gas stove or kerosene heater without ventilation and safety checks. Decide on an evacuation destination for prolonged outages.

A June night. After a week of rain the indoor hygrometer reads 85%, and black mold has grown inside the wooden nest box and on the fleece. One of two squirrel monkeys is sneezing repeatedly and its eyes are slightly red. It is eating, but does not want to go into the nest box.

What is the most appropriate response?

1. Mold is natural, so just ventilate until the rain stops
2. Remove the nest box to wash and dry it, replace the fleece, dehumidify to 50–70%, and see the vet the same day if the sneezing continues
3. Spray mold remover directly into the nest box and put it straight back
4. Turn the heater to maximum and raise the room to 32°C to drive out the moisture

AnswerB. Remove the nest box to wash and dry it, replace the fleece, dehumidify to 50–70%, and see the vet the same day if the sneezing continues

ExplanationThe right humidity is 50–70%; at 85% mold grows and its spores irritate the airways and eyes. Remove the moldy nest box, wash and dry it completely, and replace the fleece with new. Lower humidity with a dehumidifier or the air conditioner's dry mode. If sneezing or red eyes continue, see the vet the same day; if breathing becomes rapid, go now. Ventilation alone does not lower humidity. The chlorine in mold remover leaves residue that damages the monkey's airways and skin and poisons it if licked. A room at 32°C exceeds the 28°C upper limit and causes heatstroke. Wash the fleece twice a week and inspect the inside of the nest box regularly.

IssuesA hygrometer was installed but nothing was done even at 85%, and the twice-weekly fleece washing was not kept up. No rainy-season mold measures had been planned, and the sneezing and avoidance of the nest box were nearly overlooked.

ImprovementIn the rainy season keep humidity at 50–70% with a dehumidifier or air conditioner's dry mode and check the hygrometer daily. Inspect the inside of the nest box weekly and wash and dry the fleece twice a week. Keep a spare nest box and fleece, and decide that persistent sneezing, coughing or red eyes mean a same-day vet visit.

A September evening. A typhoon is expected to flood the river and an evacuation order has been issued for the area. The owner needs to evacuate with two squirrel monkeys. It is unclear whether the shelter accepts animals; a relative's home reachable by car is an hour away. Wind and rain are strengthening outside.

What is the most appropriate response?

1. The shelter will probably refuse monkeys, so leave them with extra food in the cage
2. Put both in one carrier with a towel and hand warmers, keep the car above 22°C, and evacuate to the relative's home that will take them
3. Put the two in a cardboard box and walk to the shelter
4. Wait it out on the second floor until the typhoon passes, and think again if the house floods

AnswerB. Put both in one carrier with a towel and hand warmers, keep the car above 22°C, and evacuate to the relative's home that will take them

ExplanationOnce an evacuation order is issued, the rule is to evacuate early with the animals. Squirrel monkeys settle when transported with a companion, so put both in a darkened carrier lined with a towel with a cloth-wrapped hand warmer, keep the car above 22°C, and head to the relative's home that will take them. Bring pellets, water and health records. Left behind, they die in the flooding; extra food does not ensure long-term survival. They chew through cardboard and escape, and it collapses in the rain. Deciding only after flooding cuts off escape routes and leaves both people and monkeys needing rescue. Deciding in advance on an evacuation destination that accepts animals is essential.

IssuesWhether the shelter accepted animals had not been checked in advance, causing hesitation over where to go. Although a typhoon is a predictable disaster, the timing and method of evacuation had not been decided. The state of the carrier and disaster kit was also unclear.

ImprovementCheck in advance whether municipal shelters accept animals, and decide on an alternative such as a relative's home or an animal hospital that will take them. Assemble a disaster kit: sturdy carrier, several days of pellets, water, hand warmers and health records. Agree as a family to move early once an evacuation order is issued.

A Saturday afternoon. The owner's hand was bitten by a 4-year-old squirrel monkey during care, leaving two deep wounds on a finger. They rinsed it lightly with water, put on an adhesive bandage, and carried on. The next day the wound is red, swollen and hot, the pain has spread to the palm, and the owner has a slight fever.

What is the most appropriate response at this point?

1. Apply an over-the-counter antibiotic ointment and change the bandage
2. Re-rinse the wound under running water for 15+ minutes and seek medical care immediately, saying it was a monkey bite
3. Cool the hand until the swelling goes down and wait until Monday
4. Bacteria from the monkey's mouth are the cause, so take the monkey to the vet instead

AnswerB. Re-rinse the wound under running water for 15+ minutes and seek medical care immediately, saying it was a monkey bite

ExplanationMonkey bites carry not only bacterial infection but the risk of serious zoonoses such as B virus, so the rule is to rinse under running water for 15+ minutes and seek medical care immediately. Swelling, heat and fever are signs that infection is advancing; see a doctor right away and be sure to say it was a monkey bite. Over-the-counter ointment cannot prevent deep infection. Waiting until Monday risks progression to cellulitis or sepsis. The monkey may also need a vet visit, but the owner's own treatment comes first. Do not do care bare-handed; use gloves or a thick towel, and know the bite procedure in advance.

IssuesThe monkey bite was treated like a dog or cat bite, without the 15-minute rinse and immediate medical care. Care was done bare-handed with no preparation for bites. Knowledge of zoonoses was lacking.

ImprovementUse gloves or a thick towel for care; never handle bare-handed. Share with the family the procedure: if bitten, rinse under running water for 15+ minutes, see a doctor that day, and report it as a monkey bite. Keepers should have a yearly health checkup and discuss zoonoses such as B virus with their doctor.

A spring evening. The owner finds a family member with a cold-sore blister on their lip feeding fruit mouth-to-mouth to a 2-year-old squirrel monkey. The monkey takes it happily and licks the person's face. The family member says they are just being affectionate, and the monkey shows no change yet.

What is the most appropriate response?

1. Stop the mouth-to-mouth feeding at once, keep that person away from the monkey until the herpes heals, watch the monkey's mouth and appetite daily, and see the vet now if anything is abnormal
2. The monkey has no symptoms, so it is fine to continue
3. Wipe the monkey's mouth with disinfectant and leave it at that
4. Give the monkey a small dose of human herpes medicine just in case

AnswerA. Stop the mouth-to-mouth feeding at once, keep that person away from the monkey until the herpes heals, watch the monkey's mouth and appetite daily, and see the vet now if anything is abnormal

ExplanationHuman herpes simplex virus is a fatal infection for New World monkeys such as squirrel monkeys; mouth-to-mouth feeding and kissing are strictly forbidden. Stop it immediately, keep that family member away from the monkey until the cold sore heals, and have someone else do the care. Watch daily for mouth ulcers, drooling, reduced appetite or lethargy, and if anything is abnormal, see the vet now and mention the possible exposure. Symptoms are delayed, so no symptoms does not mean safe. Wiping the mouth with disinfectant does nothing against virus inside the body and damages the mucosa. Giving human antivirals on your own judgment is wrongly dosed and dangerous.

IssuesThe family did not know human herpes is fatal to monkeys, and mouth-to-mouth feeding and kissing had become a habit. The owner had not shared infection rules with the family, and the rule of not touching the monkey with mouth sores or lip blisters was not followed.

ImprovementBan mouth-to-mouth feeding, kissing and face-licking for the whole family and explain why. Anyone with a cold sore or mouth ulcer must not touch the monkey and should hand over care. Always wash hands before and after care, and check the monkey's mouth daily. Consult a clinic that sees primates about zoonoses.

A summer midday. A 5-year-old child helped clean the cage, handling urine-marked branches and soiled pet sheets bare-handed, then ate a rice ball without washing hands. Two days later the child has a fever and watery diarrhea and complains of stomach pain.

What is the most appropriate response?

1. Treat it as a summer cold and watch with an over-the-counter probiotic
2. Take the child to a pediatrician and report that the illness began after contact with the monkey's waste
3. The monkey may not be the cause, so first check the ingredients of the rice ball
4. Just stop the child from helping with the monkey; no medical visit needed

AnswerB. Take the child to a pediatrician and report that the illness began after contact with the monkey's waste

ExplanationMonkey feces and urine can contain zoonotic bacteria such as Salmonella and Shigella, and small children are prone to severe illness. Fever and watery stool two days after handling waste is a course that suggests infection; take the child to a pediatrician and be sure to report the contact with monkey waste. This information directly guides diagnosis and treatment, and without it testing is delayed. Assuming a summer cold and waiting with probiotics risks dehydration and worsening. Checking the food first wastes time; do it alongside the visit. Not seeing a doctor harms the child's health. Washing hands with soap after care is basic for the whole family.

IssuesThe child was allowed to help clean the cage bare-handed and ate without washing hands. The family had not been told that branches and shelves are contaminated by the monkey's habit of rubbing urine on its hands and feet. Knowledge of zoonoses was not shared with the family.

ImprovementHave adults clean the cage wearing gloves, and make a rule that children do not touch waste. Always wash hands with soap after care, and make handwashing before meals a habit. Change floor sheets daily and wash branches and shelves weekly. If a family member has diarrhea or fever, mention the monkey contact when seeing a doctor.

A winter night. Of five monkeys, a 7-year-old male has been coughing for three weeks and his weight has dropped from 1 kg to 850 g. Lately he is listless and tends to stay apart from the troop. The owner has also had a cough for about two months. The other four have no symptoms so far.

What is the most appropriate response?

1. Isolate the coughing monkey in a separate room, care for him with mask and gloves, see the vet the same day, and have the owner tested at a clinic, including for tuberculosis
2. Treat it as a winter cold, warm the room, and watch with the troop together
3. To stop it spreading, just raise the nutritional value of the coughing monkey's food
4. Taking the monkey to the vet is enough; the owner need not worry about their own cough

AnswerA. Isolate the coughing monkey in a separate room, care for him with mask and gloves, see the vet the same day, and have the owner tested at a clinic, including for tuberculosis

ExplanationA cough lasting more than three weeks and weight loss over 10% are signs of a serious infection such as tuberculosis; coughing and weight loss mean an immediate visit. Tuberculosis is a zoonosis that passes both ways between humans and monkeys, so the owner's lingering cough may be related. Isolate the coughing monkey in a separate room, care for him with mask and gloves, see the vet the same day, and discuss testing the whole troop. The owner should be tested at a clinic, including for tuberculosis. Treating it as a cold and keeping the troop together spreads it to all. Changing the food alone does not stop infection. Skipping the owner's own testing leaves the source unidentified and reinfection recurs.

IssuesThree weeks of coughing and weight loss were overlooked while the troop was kept together. The owner ignored their own lingering cough and did not consider transmission from human to monkey or monkey to human. No isolation room or protective equipment had been prepared.

ImprovementDecide that coughing or weight loss means an immediate visit; weigh weekly and see the vet at a 10% loss. Secure an isolation cage and room, and keep masks and gloves on hand. Keepers should have a yearly health checkup and have any lingering cough tested, including for tuberculosis. Quarantine and test new animals at intake.

10 p.m. on a winter night. A 5-year-old squirrel monkey is lying on the cage floor and does not respond to its name. No chest movement is visible and no breath can be felt at its mouth. A hand on its chest seems to detect a faint heartbeat. It was lively until just before and seemed to have put something in its mouth.

What is the most appropriate first action?

1. Shake it hard to rouse it and throw water on it to check for a response
2. Clear any foreign object from the mouth, squeeze the left side of the chest between thumb and index finger at 120 compressions per minute, blow into the nose after every 5, and call the vet as you go
3. Put it straight in a carrier and rush to the vet without doing anything
4. If the heart is beating, breathing will return, so keep it warm and watch

AnswerB. Clear any foreign object from the mouth, squeeze the left side of the chest between thumb and index finger at 120 compressions per minute, blow into the nose after every 5, and call the vet as you go

ExplanationIf it is unresponsive and not breathing, start CPR immediately. First check for and remove any foreign object in the mouth, then squeeze the left side of the chest between thumb and index finger at 120 compressions per minute, blowing a small breath into the nose after every 5 compressions. Keep going while calling the vet and following instructions; if possible, have a family member prepare for transport. Shaking it or throwing water wastes time and causes hypothermia. Rushing to the vet without doing anything cuts off oxygen to the brain for the minutes until arrival. Even with a heartbeat, no breathing soon leads to cardiac arrest, so watching is dangerous. If a foreign object is visible, do not push it deeper.

IssuesMeasures against its habit of mouthing small objects were inadequate, creating a choking risk. The owner did not know CPR and had no after-hours clinic contact prepared. Normal breathing and heart rates were not known, so it took time to recognize the sudden change.

ImprovementMemorize the normal values (breathing 30–50/min, heart rate 150–250/min, temperature 37–39°C) and post the CPR procedure next to the cage. Keep the after-hours clinic's contact details always visible. Remove small objects that fit in the mouth from the room and keep them in locked storage.

A Sunday morning. A 3-year-old squirrel monkey has cut its right wrist on a torn section of the cage wire and blood keeps gushing out. A pool of blood has formed on the cage floor, and the monkey is moving about, flinging blood as it shakes its leg. The owner pressed with tissue, but it turned red immediately.

What is the most appropriate first action?

1. Catch it with a towel, press the wound with clean gauze for 5+ minutes, press lightly on the heart side, and go to the vet now
2. Tie a rubber band tightly around the wrist to stop the bleeding
3. Pack the wound with flour or starch to clot the blood
4. Press with gauze and lift it every 30 seconds to check whether it has stopped

AnswerA. Catch it with a towel, press the wound with clean gauze for 5+ minutes, press lightly on the heart side, and go to the vet now

ExplanationFor bleeding that keeps gushing, the basics are to catch it with a thick towel to calm it, press clean gauze on the wound, and keep pressing for 5+ minutes. For limb bleeding, pressing lightly on the heart side reduces the flow. If bleeding is heavy and will not stop, go to the vet now, keeping pressure on during transport. A tight rubber band cuts off blood flow completely, causing tissue necrosis and nerve damage. Packing with flour causes infection and interferes with treatment at the clinic. Lifting every 30 seconds tears away the forming clot and the bleeding continues. In a body of around 1 kg even a small blood loss is dangerous, so see the vet without hesitation.

IssuesThe torn cage wire went unnoticed, leaving a sharp edge exposed. No gauze or towel was ready, so tissue was used instead. The owner did not know the basic rule of bleeding control: do not lift the pressure.

ImprovementInspect the cage wire, door and branch fastenings weekly and repair tears and burrs immediately. Keep clean gauze and a thick towel as an emergency kit next to the cage. Share with the family: press for 5+ minutes without lifting, and go to the vet now if bleeding will not stop.

2 a.m. on a weeknight. A 2-year-old squirrel monkey suddenly stiffened its limbs, shook, foamed at the mouth and collapsed on the cage floor. After about a minute it went limp and barely responds to its name. It had no appetite today and ate almost none of its pellets. The regular vet opens at 9 a.m.

What is the most appropriate first action?

1. During the seizure, put a finger or stick in its mouth so it does not bite its tongue
2. It stopped after one episode, so let it sleep in the nest box until the clinic opens
3. Do not touch it during the seizure, clear objects around it; once it stops, keep it warm, dab sugar water on the corner of the mouth if conscious, call an emergency (after-hours) animal hospital and go now
4. Keep filming it, look up the cause online, and search for a remedy

AnswerC. Do not touch it during the seizure, clear objects around it; once it stops, keep it warm, dab sugar water on the corner of the mouth if conscious, call an emergency (after-hours) animal hospital and go now

ExplanationA seizure is an emergency requiring an immediate vet visit; causes include low blood sugar, poisoning, head injury and infection. Given it had not eaten, low blood sugar is likely. During the seizure, do not touch it; clear objects around it to prevent injury. Once it stops, keep it warm with a cloth-wrapped hand warmer and dab sugar water on the corner of its mouth if conscious. At the same time, call an emergency (after-hours) animal hospital and go now. Putting a finger or stick in the mouth gets you bitten and causes aspiration or tooth damage. Even after one episode, recurrence is likely, and waiting until morning risks another seizure and respiratory arrest. Video helps at the visit, but do not keep filming at the expense of acting.

IssuesNo vet visit was made when appetite was lost, and the monkey went into the night at high risk of low blood sugar. No after-hours clinic contact was prepared and the owner did not know the seizure procedure. Knowledge that a small body quickly develops low blood sugar when fasted was lacking.

ImprovementDecide that nearly 24 hours without eating means a same-day visit, and post the after-hours clinic's contact details next to the cage. Keep sugar, hand warmers, towels and a carrier in an emergency kit. Share with the family the seizure procedure: do not touch, then warm, sugar water, and go to the vet now.

A winter evening. A 4-year-old squirrel monkey that has had a runny nose for three days is now sitting on a branch breathing with its mouth open, its chest heaving fast. Its breathing rate is over 80 per minute and its lips look bluish. It is not touching its food and feels slightly cold.

What is the most appropriate first action?

1. Keep it warm in a darkened carrier and go to the vet now, quietly and without jostling
2. Hold it and keep rubbing its back to ease its breathing
3. Direct a humidifier's steam at its mouth and wait for the vet to open in the morning
4. Suction the nose hard with an aspirator and apply an over-the-counter nasal spray

AnswerA. Keep it warm in a darkened carrier and go to the vet now, quietly and without jostling

ExplanationOpen-mouth breathing, rapid breathing and bluish lips indicate severe respiratory distress with pneumonia or similar worsening rapidly. This meets the criteria for an immediate visit; 80 breaths per minute, nearly double the normal 30–50, is extremely dangerous. Line a darkened carrier with a towel, keep it warm with a cloth-wrapped hand warmer, and transport quietly without jostling. Minimizing stimulation is essential: holding it or rubbing its back increases oxygen consumption and worsens the distress. Direct steam causes burns and temperature swings, and waiting until morning risks respiratory arrest. Suction and over-the-counter nasal sprays irritate and make it worse. A vet should have been seen when the runny nose began three days ago.

IssuesNo vet visit was made three days ago when the runny nose began, allowing the respiratory infection to progress to pneumonia. There was no habit of checking breathing rate or lip color, so it went unnoticed until severe. The owner did not know that respiratory symptoms mean a same-day visit.

ImprovementDecide that coughing, runny nose or sneezing means a same-day visit, and keep the room at 22–28°C and 50–70% humidity. Memorize the normal breathing rate of 30–50 and practice counting by chest movement. Keep a carrier that can be darkened, towels and hand warmers on hand, and post the after-hours hospital's contact details.

A winter afternoon, 5°C outside. A 3-year-old squirrel monkey in free-roam time fell from a bookshelf and cannot move; it responds to its name but cannot stand. The clinic that sees primates is a 40-minute drive away. It has one cage mate, the car is ice-cold, and the owner must do the transport alone.

What is the most appropriate transport method?

1. To get there faster, drive with it held on your lap
2. Heat the car to above 22°C, put a cloth-wrapped hand warmer in a dark carrier lined with a towel, and bring the cage mate along if possible
3. To avoid the cold car, take it by train on your lap
4. A companion would excite it, so take it alone in a cardboard box

AnswerB. Heat the car to above 22°C, put a cloth-wrapped hand warmer in a dark carrier lined with a towel, and bring the cage mate along if possible

ExplanationAn animal that cannot move after a fall may have fractures, internal injuries or spinal damage; transport it warm and without jostling. In winter, first heat the car to above 22°C, put a cloth-wrapped hand warmer in a dark carrier lined with a towel, and place it inside gently without twisting its body. Transporting with a companion calms it and prevents deterioration from stress. Driving with it on your lap causes accidents, and sudden braking throws the animal. A train makes temperature control difficult and risks escape and bites to other people. Cardboard gets chewed through and is neither dark nor warm. Call ahead and report weight history, diet and stool photos.

IssuesNo preparation had been made for winter transport, such as heating the car and readying a carrier, and no procedure for handling it alone had been decided. Only the clinic 40 minutes away was known; no closer emergency option had been identified.

ImprovementKeep a carrier packed with towel, hand warmers and blanket by the front door. Set a routine of warming the car before leaving in winter and cooling it in summer. Identify several nearby clinics that see primates and after-hours hospitals, and post their numbers in the car too. Save the information to report at transport (weight, diet, stool photos) on your phone.

9 p.m. on a Friday. A 6-year-old squirrel monkey has eaten almost nothing since morning and by evening drank only a little water. It is slightly sluggish but can climb branches and responds to its name. Its stool is only slightly soft. The regular vet is open Saturday morning; the emergency (after-hours) hospital is an hour's drive away.

What is the most appropriate judgment in this situation?

1. It is mild, so watch until Monday
2. If it will not eat, offer favorite fruit or honey, and skip the vet if it eats
3. There is little need to rush to the after-hours hospital, but keep it warm, see the regular vet first thing in the morning, and go to the after-hours hospital at once if signs of deterioration appear
4. As long as it drinks water, lack of appetite is no problem, so wait for next week's checkup

AnswerC. There is little need to rush to the after-hours hospital, but keep it warm, see the regular vet first thing in the morning, and go to the after-hours hospital at once if signs of deterioration appear

ExplanationWhen it has not eaten since morning, the guideline is a same-day visit once 24 hours have passed, so seeing the regular vet first thing in the morning is a sound judgment. Overnight, keep the room above 22°C, make water available, and let it rest. However, if signs for an immediate visit appear, such as limpness with a cold body, seizures, open-mouth breathing, bloody or watery stool, or no response to its name, make the hour's drive to the emergency hospital even at night. Waiting until Monday risks low blood sugar from fasting. Eating honey or fruit briefly does not solve the cause and leads to a wrong decision about the vet. Drinking water alone does not prevent malnutrition. Prepare weight, diet and stool photos for the visit.

IssuesAppetite had been poor since morning, yet the decision about a vet visit was put off until night. The owner had no clear criteria (now, same day, within a few days) and hesitated once night fell. The after-hours hospital was far away and preparation was lacking.

ImprovementWrite down and post next to the cage: 24 hours without eating means a same-day visit, and the signs for an immediate visit (seizures, unconsciousness, cold body, open-mouth breathing, bloody stool). Record weight, diet and stool photos as soon as appetite drops, and contact the clinic so it can be seen first thing in the morning. Find a closer after-hours hospital too.
