This genus is a sister taxa to the desert hamster genus Phodopus. [2] As of 2024, two closely related species are recognized in this genus: [2] Urocricetus alticola - Ladakh dwarf hamster, native to the western Nepal, northern India, and the Chinese autonomous region of Tibet
The hamsters inhabit areas of loose sand and sparse vegetation and are rarely found in areas of dense vegetation and solid clay substrates. [8] They live at elevations of around 1,200 metres (3,900 ft)–1,450 metres (4,760 ft) and although research has been carried out, no fossil record exists for this species.
Hamsters first gained popularity as pets in the 1930s, with virtually all modern Syrian hamsters (the most common pet species) tracing their lineage back to a single litter of hamsters taken to Palestine for scientific research in 1930. Shortly thereafter, in 1938, hamsters were introduced to the United States. [17] Dwarf hamsters are also ...
Gestation lasts 16 to 18 days for Syrian hamsters, 18 to 21 days for Russian hamsters, 21 to 23 days for Chinese hamsters and 23 to 30 for Roborovski hamsters. The average litter size for Syrian hamsters is about seven pups, but can be as great as 24, which is the maximum number of pups that can be contained in the uterus.

Some dwarf hamsters are albino, in which case they will be primarily white and the fur colour characteristics will not serve to distinguish them. The characteristics ...
[1] [6] The land where the Turkish hamster lives is extremely dry and open, with fairly little vegetation aside from grasses. [1] Turkish hamsters usually live between 1,000 and 2,200 meters above sea level. [1] This hamster burrows in the ground for shelter, [1] and its burrows can be 20 inches to 6 feet below the ground surface. [1]
Cricetulus is a genus of rodent in the family Cricetidae (voles and hamsters); it has seven member species that inhabit arid or semi-arid regions in Eurasia. They tend to be more ratlike in appearance than typical hamsters, hence the common name ratlike hamster. Many of the species are considered dwarf hamsters.
Roborovski's dwarf hamster (Phodopus roborovskii) of the Cricetinae. The cricetids first evolved in the Old World during the Early Oligocene. [2] [3] They soon adapted to a wide range of habitats, and spread throughout the world. The voles and lemmings arose later, during the Pliocene, and rapidly diversified during the Pleistocene. [4]
