Ferret

Insulinoma

SignsStaring blankly, wobbly hind legs, drooling, pawing at the mouth, collapse from low blood sugar

PreventionNo established prevention. From age 3, a checkup every 6 months including blood glucose. Do not give sugary treats

Adrenal disease

SignsSymmetrical hair loss starting at the tail or back, itchy skin, swollen vulva in females, difficulty urinating in males

PreventionEarly detection is key. See the vet if you notice hair loss. Can sometimes be managed with hormone treatment

Lymphoma

SignsSwollen lymph nodes, lethargy, weight loss, rapid breathing; can occur even in young ferrets

PreventionNo prevention. Feel the neck, armpits and backs of the knees for lumps once a week. Checkup every 6 months

Distemper

SignsEye and nasal discharge, hardened skin on the footpads and chin, fever, neurological signs as it progresses. Nearly 100% fatal

PreventionAnnual vaccination. Avoid contact with dogs and walks outdoors until vaccination is complete

Heartworm disease

SignsCoughing, difficulty breathing, lethargy, swollen belly. Even a few worms cause severe disease because the heart is so small

PreventionMonthly preventive medication during mosquito season. Keep mosquitoes out even indoors

Gastrointestinal foreign body

SignsVomiting, loss of appetite, no stool or thin stool, painful belly, lethargy

PreventionKeep rubber, sponge and fabric items out of the room. Never leave a free-roaming ferret unsupervised. Use Laxatone to prevent hairballs

Falls and fractures

PreventionThey can climb sofas and shelves, so do not let them get up high. When holding, support the chest and hips; if it struggles, lower it to the floor

First aidIf it will not move or drags a leg, place it in a small box and keep it still. Do not touch the leg; see the vet the same day

Caught in a door or drawer

PreventionThey squeeze into gaps. Always check where the ferret is before opening or closing anything. Check inside drawers and the washing machine too

First aidDo not touch the crushed area. If breathing is abnormal, there is bleeding, or it cannot move, go to the vet immediately. Internal injury is possible

Heatstroke

PreventionExtremely sensitive to heat. Keep the room below 28°C. In summer run the air conditioner continuously, even when you are out

First aidMove to a cool place, wrap the body in a wet towel, aim a fan at it, and go to the vet immediately. Avoid ice water

Bites from cage mates, dogs or cats

PreventionSeparate ferrets if play gets too rough. Never leave them unsupervised with dogs or cats. Introduce newcomers in a separate cage

First aidRinse the wound under running water and press with clean gauze. For wounds on the neck or belly, or bleeding that will not stop, see the vet the same day

Influenza

RouteSpreads by droplets from people to ferrets and vice versa

PreventionIf you are sick, wear a mask, wash your hands and let another family member do the care. See the vet if the ferret has fever or a runny nose

Ringworm (dermatophytosis)

RouteContact with the skin or fur of an infected animal

PreventionIf there is hair loss or dandruff, wash your hands after touching. Do not cuddle it until treated

Salmonellosis

RouteFeces, litter box cleaning, handling raw-meat diets

PreventionWash your hands after care. Do not feed raw meat; clean the litter box daily

Sarcoptic mange (mites)

RouteMites infest the skin through contact with an infected animal

PreventionIf there is itching or scabs, see the vet for deworming. Wash the bedding

Food

• Ferret-specific food available at all times
• At least 35% animal protein and around 20% fat
• Laxatone 2–3 times a week to prevent hairballs

Water

• Fresh water at all times in both a bottle and a bowl
• In summer, place water in several spots and check how much is drunk

Toys & play

• Tunnels, fabric tubes, balls (watch for swallowing)
• Avoid squeaky toys and latex items
• Run around with it during playtime

Nest, bed & hideout

• Hang a hammock on the upper level
• Fabric sleeping bag or towel; a blanket in cold weather

Bedding & litter

• No substrate needed; line with towels or mats
• Non-clumping paper or wood litter
• Place the litter box in a corner and remove droppings daily

Cage / housing material

Multi-level wire cage with a locking door

Size & space

At least 70 cm W x 50 cm D x 60 cm H; always provide playtime outside the cage

Layout

• Hammock on the top level, litter box in the opposite corner
• Keep food and water away from the sleeping area
• Add intermediate steps between levels to prevent falls

Placement notes

• Avoid direct sunlight and heat near windows
• They escape through door gaps, so check the lock

Exercise, free-roam & walks

• Let it out of the cage to play 2–4 hours a day
• Clear gaps, cords and small objects from the room first
• A harness is essential for outdoor walks; beware of extreme heat and dogs

Temperature & humidity

Temperature15–24°C; above 28°C there is a risk of heatstroke

Humidity40–60%

Summer & winter

• In summer run the air conditioner continuously, even when you are out
• In winter provide a sleeping bag and blanket; beware of burns from heaters

Nail trimming

Every 2–3 weeks with pet nail clippers, stopping short of the quick. Dabbing Laxatone on its belly as a distraction makes trimming easier

Brushing, skin & coat care

During shedding season, brush 2–3 times a week to prevent hairballs. Bathe no more than once a month; over-washing makes the odor stronger

Other care

Wipe visible ear wax with a cotton swab once a week. Lots of black ear wax suggests ear mites. Check for tartar regularly too

Protection from predators

• Never leave it unsupervised with dogs or cats; keep large dogs in another room
• Outdoors, beware of crows, stray dogs and birds of prey
• Keep mosquitoes out for heartworm prevention; window screens are essential

Foreign-body ingestion

Swallowing rubber, sponge, fabric or earbuds is the most common accident. Clear all small objects from the play room; if no stool is passed, see the vet the same day

Being stepped on

They cling to your feet. Watch your step when walking and tell the whole family. If you step on it, keep it still and see the vet

Getting pinched

They crawl into doors, drawers, recliner sofas and washing machines. Always check where the ferret is before opening or closing anything or using an appliance

Falls

They are not afraid of heights and jump off, causing fractures. Keep them away from shelves and balconies. If it does not move after a fall, do not touch it; see the vet

Escape

They escape through tiny gaps. Fit barriers at window screens and the front door and microchip the ferret. If it escapes, search with neighbors and on social media and lure it with the scent of its bedding

Safe release procedure

1. Stay still and relax to calm it down
2. Grasp the scruff of the neck and lift gently
3. Offer Laxatone or food near its mouth
4. Once it lets go, return it quietly to the cage and let it settle

After the release

Rinse the wound under running water and disinfect. For deep wounds, swelling or fever, see a doctor. Review why it bit (pain, overexcited play)

What to tell the vet & what to bring

Age, whether spayed/neutered, vaccination and heartworm prevention history, course of hair loss or other symptoms, photos of stool or vomit

Checking consciousness, breathing & heartbeat

• Does it respond to its name or a touch on the nose?
• Watch the chest. Normal breathing is about 35 breaths per minute
• Place fingers on the chest. Normal heart rate is about 200–250 beats per minute

Stopping bleeding

• Press firmly on the wound with clean gauze for 5 minutes
• Raise limbs above the heart. Use styptic powder for nail bleeding
• After bleeding stops, keep it warm in a towel and see the vet

Transport

• Small carrier lined with a towel, kept dark and quiet
• Wrap hand warmers in a towel; never place them directly against the body
