Dwarf Hamsters or phodopus are the a member of the vole and hamster family and are known as dwarf hamsters because of their small size.
The three main species kept as pets are:
- Phodopus campbelli - Campbell's dwarf hamster
- Phodopus roborovskii - Roborovski's (desert) dwarf hamster
- Phodopus sungorus - Djungarian hamster (Winter white Russian dwarf hamster)
The colour genetics of dwarf hamsters is much less than thta in syrian hamsters. If handled often, they can become tame quickly and become good pets.
Russian dwraf hamsters and Campbell's dwarf hamster generally live for 1.5 - 2.5 years. They reach a length of 8cm - 10cm. However, Chinese dwarf hamsters live for 2.5 - 3.5 years. they reach a length of 10cm - 12cm. The Roborovski hamster is the smallest at only 4–5 cm and lives for 3 to 3.5 years.
These subspecies are quite similar, so it is hard to tell them apart unless you can identify them from their colour genetics and size.
