The golden hamster or Syrian hamster (Mesocricetus auratus) is a member of the subfamily Cricetinae, the hamsters. In the wild, they are now considered vulnerable. Their natural geographical range is limited to the north of Syria and the south of Turkey, in arid habitats. Their numbers have been declining due to loss of habitat caused by agriculture and deliberate destruction by humans. However, captive-breeding programs are well established, and captive-bred golden hamsters are often kept as pets. They are also used as scientific research animals throughout the world.
