The Roborovski hamster is a small, lively rodent native to the deserts of Mongolia and China. They are one of the smallest hamster species, typically measuring about 2 to 4 inches in length. Known for their sandy-colored fur and white underbellies, these hamsters are social creatures that thrive in groups, making them more active and playful than other hamster types. Roborovski hamsters are popular pets due to their friendly nature and low maintenance needs. They require a spacious cage with plenty of bedding, tunnels, and exercise wheels to keep them entertained. Their diet mainly consists of commercial hamster pellets, fresh vegetables, and occasional treats.
