Chinese Hamster — care sheet
Cricetulus griseus · Beginner–Intermediate
| Adult size | Slim and mouse-like — body about 8–13 cm (3–5 in) with an unusually long 2–3 cm tail, weighing roughly 30–45 g. |
|---|---|
| Lifespan | Typically 2–3 years as a pet. |
| 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. |
| Bedding & 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 & exercise | 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. |
| Grooming & upkeep | Self-grooming; a sand bath keeps the coat clean. Provide gnaw items for the continuously-growing teeth. |
| 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. |
Before you buy
- In the US: is it legal where you live? (California bans keeping Chinese hamsters as pets.)
- Can you provide a much larger, deep-bedded enclosure than pet shops sell?
- Do you understand it must live alone — it’s territorial, not a group dwarf?
- Are you patient with a nervous, sometimes-nippy youngster that tames with time?
- Do you have an exotic vet that treats hamsters, and accept a 2–3 year lifespan?
See a small-animal or exotics vet if…
- 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
Never
- Never keep two Chinese hamsters together, or mix species or sexes.
- Never keep one in California (or anywhere it’s restricted) without the required permit.
- Never use cotton-wool or fluffy strand bedding, or a wire-mesh floor.
- Never let it get cold enough to risk torpor, or leave it in direct heat.
