The winter white dwarf hamster (Phodopus sungorus), also known as the Russian dwarf hamster, Djungarian hamster, striped dwarf hamster, Siberian hamster or Siberian dwarf hamster, is one of three species of hamster in the genus Phodopus. It is ball-shaped and typically half the size of the Syrian hamster, so is called a dwarf hamster along with all Phodopus species.
The hamsters are often found on the pet market in Europe, Japan, and North America. Care of the hamster is similar to all other species of Phodopus. The hamsters, along with most rodents, are prone to tumours. They can also receive injury in the cheek pouch by sharp objects damaging the fragile inner lining. Other health problems include bite wounds, broken teeth, constipation, dehydration, dental malocclusion, diarrhea, and ear problems. The hamster is easy to tame. In addition to natural colourings in the wild (“ruddy” or “agouti”), the hamsters in captivity occur in a variety of different colors. They are prone to diabetes so, when in captivity, you should always watch their sugar intake. Avoid foods such as corn, cherries, bananas and grapes in large amounts because they are high in sugar. The hamsters should be fed dry food, fruits and vegetables. When being fed fruits and vegetables, make sure that for every fruit that there is a vegetable to balance out the sugar intake.
