Then scientists checked wild ones. > **Lab versus wild.** Female hamsters in the wild were almost exclusively diurnal, which means active by day. Lab hamsters are nocturnal. Lab and wild hamsters are the same species, but a result from one may not hold for the other. ## Small, Fast, and Short-Lived An adult golden hamster weighs 100 to 125 g and is about 13 to 13.5 cm long. A database of animal ageing gives an average adult weight of 105 g. Its pregnancy lasts 16 days, the shortest among eutherian mammals. Eutherians are the placental mammals, the group that includes us. A birth brings 8 to 12 young, born with their eyes closed. They open them at 12 to 14 days and are weaned at 19 to 21 days. Females are sexually mature at 26 to 30 days on average, males at 42 days. In the wild, a golden hamster lives 1.5 to 2 years on average. In captivity a typical life is 2 to 2.5 years, and the ageing database's maximum for captivity is 3.9 years. ## A Loner With a Burrow Wild golden hamsters live mainly on the Aleppo plateau in Syria, with reports from eastern Turkey. A field survey near Aleppo found most burrows on farm fields, especially in legume crops. Burrows were 36 to 106 cm deep, with one vertical entrance leading to a nesting chamber and at least one food chamber. None of the inhabited burrows held more than one adult. Golden hamsters are solitary and highly territorial, and they eat seeds, nuts and insects, caching food in the burrow. They are aggressive toward each other except when mating. Teeth chattering, a sign of aggression, was recorded in 92 percent of male-to-male meetings. Foxes, mustelids, birds of prey and snakes are among its predators, and it avoids them by sheltering in its burrow and staying alert. ## Endangered in the Wild, Worldwide as a Pet The Red List rates the species Endangered. Animal Diversity Web says wild populations are restricted to a small area of the Middle East and describes wild golden hamsters as crop pests. Because golden hamsters are widely used as pets and research animals, it says the species is in no danger of dying out fully. The wild populations are the ones under threat. ## Frequently Asked Questions ### Why did scientists go looking for wild golden hamsters in 1997 and 1999? To confirm that the species still lived wild in northern Syria. On two expeditions, in September 1997 and March 1999, researchers caught six females and seven males near Aleppo, and one pregnant female gave birth to six pups. All 19 hamsters were moved to Germany, where they and three wild hamsters from the University of Aleppo founded a new breeding stock. *(Source: [Gattermann et al. 2001]())* ### Do golden hamsters share a burrow? Not in the wild, where they live alone. Communication is mostly by scent: a hamster rubs scent glands on its flanks against surfaces, and the marks can carry information such as kinship. The closest measurement between two occupied wild burrows was 118 m. *(Source: [Animal Diversity Web, University of Michigan]())* ### Why do hamster mothers sometimes eat some of their pups? The mother raises her litter alone, and she may cut its size by cannibalism. Animal Diversity Web says that in the wild this is likely a response to scarce resources, while in a cage it is often a reaction to a disturbance caused by people. *(Source: [Animal Diversity Web, University of Michigan]())* ## Sources 1.
