Saw these cutie baby hamsters at Petco so I took a video of them.
Roborovskis (Phodopus roborovskii) or desert hamster is the smallest of all hamsters, averaging under an inch (2 cm) at birth, and (rarely) three inches (7.5 cm) during adulthood. Distinguishing characteristics of the Roborovskis are eyebrow-like white spots, and the lack of any dorsal stripe (found on the other members of the Phodopus genus). The average lifespan for the Roborovski hamster is three (3) years, though this is dependent on living conditions (extremes being four years in captivity and two in the wild). Although claimed to be hypoallergenic, Roborovski hamsters have been associated with the development of asthma in previously asymptomatic owners.
