Your Chinese Hamster Vet-Prep Sheet
Hayfold a warm home for small-pet folk · hayfold.com 🔍 Find an exotic-mammal vet — before you need one
- Search the AEMV find-a-vet directory (the Association of Exotic Mammal Veterinarians), or, in the UK, the RCVS Find-a-Vet tool — or search “exotic / small-mammal vet near me”.
- Call ahead and ask the key question: “Do you see small / exotic mammals?” Not every vet does. Ask the exam fee while you’re on the phone, so the cost is one less panic in a crisis.
- Find and save one now, while things are calm — not in the middle of an emergency.
📇 Fill this in now — before the crisis
Two minutes now saves ten in a panic. Print it and keep it with your care notes.
🚨 Is this an emergency now?
See a vet promptly if you notice any of these:
- A wet, soiled rear end with diarrhoea and low energy — “wet tail” is a fast, often fatal emergency
- Not eating, weight loss, or a hunched, low-energy hamster
- Excessive drinking or urinating, or unexplained weight change (keep sugar low)
- Any lump or swelling, or overgrown front teeth
- A hamster that is cold and stiff (torpor) — warm it gently and seek advice
When in doubt, a vet call is never wrong — most issues are reversible if caught early.
🚗 On the way / while you wait
✅ Do
- Keep it warm — small mammals chill and dehydrate fast, and cold makes almost everything worse.
- Bring it in its own bedding/carrier with some familiar food.
- For rabbits and guinea pigs, keep offering their normal hay, greens and water — a gut that stops is an emergency.
- Bring a fresh dropping or urine sample if you can.
- Keep it calm and quiet.
⛔ Don’t
- Don’t give any human or OTC medicines — some common antibiotics are fatal to rabbits and guinea pigs.
- Don’t withhold food from a rabbit or guinea pig.
- Don’t let it get cold.
- Don’t handle it more than necessary.
🎒 What to bring
- A fresh dropping or urine sample, if you can collect one.
- Photos and a short video of the behaviour or symptom — it may not show it in the clinic.
- A note of your setup and exactly what — and how often — you feed.
- A note of eating, drinking and toileting over the last day.
- The animal in a secure, warm carrier.
🗣️ What to tell the vet
A general vet may not know this species. Come ready to explain its correct care:
- Enclosure
- Far bigger than shop cages, with a solid floor and deep bedding to tunnel. A tank with a ventilated lid or a narrow-barred cage suits this small, agile climber — with a nest box, sand to dig, and hides.
- Companionship
- Best kept solitary. Chinese hamsters are naturally territorial and tend to become aggressive toward cage-mates — especially in a cage that’s too small — so, like the Syrian, they should live on their own. Never mix species or sexes.
- Temperature
- Keep indoors, warm and out of draughts and damp. Too cold and a hamster can slip into a dangerous torpor — warm a cold, stiff hamster gently, offer food and water, and call a vet if unsure.
- Substrate
- A deep layer of safe paper-based bedding over a solid floor, plus a sand area. Never cotton-wool or fluffy strand bedding.
- Enrichment
- Nocturnal, active and an agile climber — a large solid axle-free wheel, tunnels, deep bedding, sand and safe gnaw items; scatter-feeding suits their foraging.
- Diet
- A good-quality hamster pellet or seed/grain mix with constant fresh water. As a small dwarf-type it’s sensible to keep sugar low — avoid sugary muesli-style mixes and limit fruit.
- Supplements
- None needed on a good, varied hamster diet.
⚕️ Small mammals are prey animals and hide illness until it is advanced, so any change in eating, droppings, drinking or behaviour is urgent — in rabbits and guinea pigs, not eating or passing no droppings for 12–24 hours can be a life-threatening emergency (gut stasis). They also chill and dehydrate quickly, so keep it warm. Tell the vet about your diet and any remedies you’ve used, and ask for exotic-mammal-safe medicines and doses — several antibiotics that are routine in other pets are dangerous to rabbits and guinea pigs.
⚕️ Diarrhoea with a wet, dirty rear end is a rapidly progressing emergency in hamsters and needs a vet the same day, not a clean-up.
Then note which of the warning signs (above) you are seeing, when they started, and whether they are getting worse.
❓ Questions to ask
- Do you routinely see small / exotic mammals? If not, can you refer me to a vet who does?
- What are the likely causes — and could my setup or diet be contributing?
- What is the treatment plan, the likely cost, and what should I watch for at home?
- How do I prevent this from happening again?
