Types of Russian Dwarf Hamsters

Campbell's Dwarf Hamster

• Known more commonly as Campbell's dwarf hamsters, these little creatures' scientific name is Phodopus sungoris campbelli. When full grown, they stretch about 10 to 12 centimeters. Their bodies are round and have tiny features that include their feet, ears and tails, though their eyes are larger. If found in the wild, they may display a stripe down their backs or vary in color. The diet of the Campbell's dwarf hamster consists of mouse mix combined with fruit and vegetables. Treats can include crickets, meal worms and vitamins, such as ones that include calcium. Their habitats should include bedding and at least a 10-gallon tank. They also should have at least one companion. Examples of ways to keep them entertained include chew toys, tunnels and ramps. The Campbell's dwarf hamster typically lives two years.

Winter White Dwarf Hamster

• Winter white dwarf hamsters, also known as Phodopus sungorus, are similar to the Campbell's dwarf hamster except they vary more in color and have a more distinct nose. They got their name by the ability to turn white during the winter to hide from predators. They too will grow to about 10 to 12 centimeters in size, and enjoy fruits, vegetables, meal worms and crickets. Like the Campbell's dwarf hamster, they enjoy having a companion, though if they are of a different sex, be prepared for mating. If they are of the same sex, introduce them to each other at a young age to ensure better compatibility. Their bedding should consist of paper-based materials or hay. Avoid pine or cedar. The winter white dwarf hamster's activity level typically is very high, so include items in their habitat to keep them busy, such as ramps, tunnels and wheels. Chew toys also satisfy their curiosity. They typically live about two years.

Chinese Dwarf Hamster

• Before purchasing a Chinese dwarf hamster, check to see if this type of Russian dwarf hamster is legal in your state. The Chinese dwarf hamster is illegal in several states, including California, because of their threat to native species if released into the wild. If legal in your state, the Chinese dwarf hamster can make a good pet for a more experienced hamster owner. Because they are very aggressive, they can overwhelm someone who is not used to dealing with a hamster that jumps high and is fast. Like other Russian dwarf hamsters, they grow to about 10 to 12 centimeters. They typically have an appearance of a rat, and the males have large scrotal sacs. Although they are considered animals that live in communities, fights can break out in habitats. For less experienced hamster owners, owning two females introduced at a very young age are the best way to ensure harmony in the habitat. No more than two should be placed in one habitat, and the habitat should include several places to hide and explore. Food for these types of hamsters include mouse food, fruit, vegetables, meal worms, crickets and occasional vitamins. They typically live two to three years.
