Roborovski dwarf hamster

[3] Distinguishing characteristics of the Roborovskis are eyebrow-like white spots and the lack of any dorsal stripe (found on the other members of the genus Phodopus).

[5] The common name and scientific name honor the Russian explorer Vladimir Ivanovich Roborovski, who collected the holotype of this species.

It primarily lives on the seed of the sand alyssum, nitre bush, Siberian peashrub, Dracocephalum peregrinum, and milkvetch as well as sedges during the summer-months.

[16] The daily dietary intake of the Roborovski hamster heavily depends on its body weight.

Based on its population structure, Wan et al. calculated an average food intake of ca.

)[20][21] Continental European countries had more success in breeding some Roborovskis, and those currently in the UK are descendants of a batch imported from the Netherlands in 1990.

The cusps of the lower molars are directly opposite and not alternate, as seen in other members of the genus, and the incisive foramen of the Roborovski hamster is greater than 4 millimetres (0.16 in) in length and is shorter than the length of the upper tooth row, which is uncharacteristic of the other two members of the genus.

The homozygous carrier of the gene variant causes neurological symptoms similar to the whirling disease, where the animal spins itself around until it dies of exhaustion.

Males usually have a visible scent gland near the navel above the two openings, appearing as a yellow stain in older animals.

[31][32] At birth, the offspring have no fur, the incisors and claws are visible, but the eyes, pinnae of the ear and digits are all sealed.

They are best suited to life as merely observational creatures, with limited interaction between them and humans, due to their increased activity levels that lead to a high stress predisposition and decreased ease of handling when compared to other domestic hamster species.

[33] Although claimed to be hypoallergenic, Roborovski hamsters have been associated with the development of asthma in previously asymptomatic owners.

[34] In rare emergency situations, a shallow dish of warm water may be necessary to clean harmful substances from a hamster's fur; however, under normal circumstances, hamsters should never be bathed in water as, aside from being incredibly stressful, this can remove vital protective oils from their coat, which can be dangerous and potentially fatal.

[35][36] Hamsters frequently groom themselves, and instead of water, a sand bath should be offered to help them stay clean and healthy.
