Roborovski Hamster — care sheet
Phodopus roborovskii · Beginner–Intermediate
| Adult size | The smallest pet hamster — head-and-body about 5–8 cm (2–3 in) with a tiny tail, weighing roughly 18–27 g. |
|---|---|
| Lifespan | The longest-lived pet hamster — typically about 3–3.5 years. |
| Enclosure | Far bigger than shop cages, with a solid floor and deep bedding to tunnel. A glass or plastic tank with a ventilated lid is ideal — Robos are small enough to squeeze through wide bars — with a deep sand area (they love to dig and sand-bathe), a nest box and multiple hides. |
| Companionship | Doesn’t need company, but of the pet hamsters the Roborovski is the one most likely to tolerate a same-sex pair or trio IF the group is formed young from litter-mates and stays harmonious. Even then pairs can fall out later, so only try it with a spare cage ready to separate them for good. A single Robo is perfectly happy. |
| Temperature | Keep indoors, warm and out of draughts and damp. A hamster that gets too cold 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 generous area of coarse sand for digging and bathing (Robos are desert animals). Never cotton-wool or fluffy strand bedding. |
| Enrichment & exercise | Astonishingly active and nocturnal — give lots of floor space, a large solid axle-free wheel, tunnels, deep sand to dig, and safe things to gnaw. Scatter-feeding suits their foraging. |
| Grooming & upkeep | Self-grooming; a sand bath keeps the coat in great condition. Provide gnaw items so the continuously-growing teeth wear down. |
| Diet | A good-quality hamster pellet or seed/grain mix, with constant fresh water. Robos are not among the diabetes-prone lines, but avoid sugary muesli-style mixes and excess fruit as a sensible dwarf precaution. |
| Supplements | None needed on a good, varied hamster diet. |
Before you buy
- Are you happy with a watch-don’t-hold pet that’s too fast to cuddle?
- Can you provide a large tank-style enclosure (bars are an escape risk) with deep bedding and a sand area?
- Do you understand it doesn’t need company, and that any pair needs a spare cage on standby?
- Can you keep it warm indoors and offer a large solid wheel?
- Do you have an exotic vet that treats hamsters?
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
- Laboured breathing, any lump, or overgrown front teeth
- A hamster that is cold and stiff (torpor) — warm it gently and seek advice
- Diarrhoea after any medication — some antibiotics are fatal to hamsters
Never
- Never house a Robo in a wide-barred cage it can escape, or on a wire-mesh floor.
- Never use cotton-wool or fluffy strand bedding.
- Never force handling on such a fast, flighty animal — you’ll cause stress and falls.
- Never let it get cold enough to risk torpor, or leave it in direct heat.
