In addition, the widespread breeding and distribution of hybrids could threaten the existence of both pure species and subspecies of the ecosystem, resulting in only mongrels. Hybridizing causes each litter to become smaller and the young begin to form congenital problems. Conservation status This hamster is listed as of Least Concern by the International Union for Conservation of Nature (IUCN). The population and distribution size are large, and no major or widespread threats to the species are known. Population numbers in the wild are not recorded.
