Hamsters are rodents (order Rodentia) belonging to the subfamily Cricetinae, which contains about 25 species classified in six or seven genera. They have become established as popular small house pets, and because they are easy to breed in captivity, hamsters are often used as laboratory animals.

They feed primarily on seeds, fruits, and vegetation, and will occasionally eat burrowing insects. They have elongated cheek pouches extending to their shoulders, using them to carry food back to their burrows....LESS
