The Roborovski hamster, often called the Robo hamster, is one of the smallest and fastest species of pet hamsters. Native to the deserts of Mongolia and China, these little creatures are known for their playful and energetic nature. They typically have a sandy-brown coat with white underbellies, making them quite adorable and easy to care for. Roborovski hamsters are social animals that thrive in pairs or small groups, unlike many other hamster species that prefer solitude. They enjoy running on wheels and exploring their habitats, which can be enriched with tunnels and toys. Their lively personality and small size make them a popular choice for pet owners.
