The Campbell's Russian Dwarf hamster is native to the steppes and semiarid parts of central Asia and parts of Northeastern China. It is often confused or mislabelled as a Winter White hamster since the two species can interbreed and produce hybrids; this is not recommended and is causing fertility and breeding issues.
The Campbells Dwarf hamster lives around 1-2 years and is sometimes referred to as the Furry or Hairy Footed Hamster. They measure around 10-12 cm and typically weigh between 50-75g. Males tend to be larger than females.
Unlike Syrian hamsters, Campbell Hamsters are sociable and will live with company, providing they are introduced at a young age. In the wild they would live in pairs or small groups until mature, so equally in captivity it is not advisable to introduce adult animals since they will see this as an invasion of their territory and fights are likely to occur.
The Campbell Hamster have multiple scent glands located on their face, behind their ears, on their cheek pouches and belly. This may be in part, compensation for their rather poor eyesight and terrible depth perception. In a new environment, a Campbells hamster may groom itself to scent its feet - enabling it to use this trail of scent to find its way back to its burrow.
Campbells hamster should have a large cage, if using a tank then a mesh lid must be provided and the tank should not be too tall. They benefit from a dust bath, and a solid based wheel. Multiple nests should be provided, ideally with more than one entrance hole.
Campbells hamsters are prone to diabetes so care should be taken with their diet. Commercial treats and sugary foods must be avoided. Their diet in the wild would consist of various seeds, grains and vegetables but some seed mixes will contain items that should not be given to a Campbell hamster. See further reading for details.
Breeding
Due to the over-abundance of hamsters in rescue centres breeding should be considered very carefully and only undertaken by experienced rodent keepers.
The following information is derived from my own research, and not personal experience and should not be considered as an definitive list. Please remember that your females should not be bred for the first time too young, or too old and it is important to give the female a resting period between litters. Back-to-back litters, with no resting period will take a huge toll on a female and will drastically shorten her lifespan.
It is also important to check whether the male can be left in with the litter or must be removed and to research the proper introduction methods for mating. The nest and pups should not be disturbed for the first 14 days due to the possibility that this could upset the mother and lead to her killing her young.
Please see when to breed rodents: ethics and care for more information.
Campbells Hamsters become sexually mature at 5 weeks although it is recommended to wait until they are 3 months of age before their first litter. Gestation of 18-21 days with litter sizes around 4-6. The female can mate immediately after giving birth so male and female should be separated to prevent back-to-back litters.
They can be separated into same-sex pairs at 4 weeks to prevent inbreeding.
