Meet the Roborovski Hamster
Officially called the Roborovski hamster, this tiny dwarf species is often referred to as the “Granpa hamster” or simply dwarf hamster. It’s the smallest hamster breed, native to the deserts of Central Asia—such as Mongolia, Kazakhstan, and northern China—also known as the desert dwarf hamster. Its signature look includes a petite body and distinctive white eyebrow markings.
Traits, Behavior & Lifespan
- Size: 1.5–2 in
- Weight: 12–24 g
- Lifespan: About 3 years, sometimes up to 4
- Color: Sandy-colored back, white belly, and white eyebrows
- Behavior: Nocturnal, extremely active and agile. Uniquely social among hamsters—enjoys living in groups. They’re timid and not ideal for children or those who like holding pets frequently due to their small, fragile bodies.
- Note: Keep same-sex Roborovski hamsters together to avoid overbreeding.
Ideal Living Conditions
Recommended Temperature
71.6–82.4°F (22–28°C). Extreme heat or cold is harmful. Use ceramic hideouts or metal cooling plates in summer, and wrap a warm pack in a towel under the cage in winter. Never place the cage outdoors due to noise or weather — this can be fatal.

Cage Size & Setup
Despite being small, Roborovski hamsters are highly active and social, so they need space. Use a minimum 40×60 cm base, similar to that of a Syrian hamster. Avoid traditional wire cages, as these hamsters may squeeze right through the bars. Keep the cage away from drafts and direct sunlight to maintain a stable temperature.
Keep their environment quiet — they’re sensitive to noise and can easily be startled, which disrupts bonding progress.
