The dwarf hamster is a small rodent that belongs to the family Cricetidae. They are popular pets due to their small size, typically measuring about 2 to 4 inches long. Dwarf hamsters are known for their friendly nature and can be found in various species, including the Roborovski and Campbell's dwarf hamster. These hamsters are nocturnal, meaning they are most active at night. They require a spacious cage with plenty of bedding, toys, and a wheel for exercise. Dwarf hamsters are social animals and can sometimes live in pairs or small groups, but it's essential to monitor their interactions to prevent aggression.
