The Smallest Hamster Breed: Roborovski Hamster
The smallest hamster species is the Roborovski hamster (scientific name: Phodopus roborovskii), characterized by these traits:
1. Physical Characteristics
- Tiny Size: Only 4–5 cm in length, with short limbs and a stubby tail—the smallest known hamster breed.
- Distinctive Look: Light yellow fur on the back, white whiskers and eyebrows, earning it the nickname "Grandpa Hamster" due to its elderly appearance.
2. Behavioral Traits
- Nervous Nature: Shy and sensitive, highly reactive to sounds and light—requires a quiet environment.
- Nocturnal Habits: Active primarily at night, typical of nocturnal animals.
3. Care Tips
- Escape-Proof Cage: Use enclosures with small gaps (like acrylic cages) to prevent escapes.
- Temperature Control: Maintain 20–28°C (68–82°F), avoiding direct sunlight or air conditioning drafts.
Though popular for its tiny size and longer lifespan (2–3.5 years), this breed is better for observation than close interaction due to its skittish nature.
