Have you had the chance to look at Hamster Centrals Info and Articles section? If not you really should give some of them a read. We have information about each kind of hamster you can buy with pictures of that type.
Perhaps if you take a look you’ll be able to tell us what kind of hamster it is? If you can post pictures that would be even more helpful!
Welcome to the community, dont forget to post an intro and tell us more about yourself!
