About the Campbell's dwarf hamster
Campbell's dwarf hamster is a small, round hamster from the steppes and semi-deserts of Mongolia, northern China and southern Russia. It is closely related to the Winter White, and the two are often crossed in the pet trade.
Campbell's are active and curious, but some can be nippy, especially if not handled regularly. Like Winter Whites, they are prone to diabetes, so diet matters.
Temperament
Campbell's hamsters are lively and curious, with individuals ranging from calm to quite nippy. Regular, gentle handling helps them become tame. They are mostly active in the evening and at night.
Housing
Provide a large enclosure with deep bedding for burrowing and plenty of floor space. A solid-surface wheel of suitable size, often around 20 cm or larger, lets them run comfortably. Keep the enclosure in a quiet, stable room away from direct sunlight and draughts.
Diet
Feed a low-sugar dwarf hamster mix or lab block, scattered to encourage foraging. Avoid fruit and sugary treats because of diabetes risk. Provide small amounts of fresh vegetables, occasional protein and fresh water at all times.
Exercise & enrichment
Hides, tunnels, chew items, sand baths and foraging opportunities keep them active. Change the layout periodically to add interest. Handle gently and frequently, close to the ground, to build trust.
Grooming
Campbell's hamsters groom themselves and rarely need help. Check teeth and nails occasionally and keep the enclosure clean.
Health
Diabetes is a known risk in Campbell's hamsters, often showing as increased thirst and urination. They are also prone to wet tail, dental problems, eye problems and tumours. Pairs can fight, causing injuries.

Common questions
Do Campbell's hamsters bite?
Some can be nippy, especially if startled or rarely handled. Gentle, regular handling usually helps.
What is the difference between a Campbell's and a Winter White hamster?
They are closely related species. Campbell's tend to have smaller ears and a wider range of colours, and they do not usually turn white in winter.
Can Campbell's hamsters eat fruit?
Because they are prone to diabetes, sugary foods such as fruit are best avoided or kept to a tiny, rare treat. Vegetables are a better choice.
