Winter white dwarf hamsters, also known as Russian dwarf hamsters, are a small hamster species with a social personality. As pets, they usually are docile and take well to handling, though they can be difficult to hold due to their small size and quickness. They are around half the size of the Syrian hamster that is also commonly seen as a pet.
The coat of winter white dwarf hamsters is actually a greyish-brown colour for most of the year. But in the winter it changes to white to act as camouflage in the snow. In captivity, the coat isn’t guaranteed to change colours if the hamster isn’t exposed to the shorter winter light patterns. These hamsters are typically easy to care for as pets, requiring a fairly straightforward diet and housing setup.
