European (Common-Black Bellied)

The European hamster, (Cricetus cricetus), also known as the black-bellied hamster or common hamster, is a hamster which is the only species of the genus Cricetus. It is native to a large global range, extending from western Europe, through central and eastern Europe, Russia, and Kazakhstan, reaching as far east as the Yenisey river. The animal is widely considered a farmland pest, and has also been trapped for its fur. Across its global range it is considered of least concern but in many individual European countries it is considered critically endangered.
