Hamster Fact: Hamsters are of the subfamily Cricetinae, which there are 18 species of. The scientific name for the Syrian Hamster is Mesocricetus auratus. AKA the teddy bear hamster, golden hamster, fancy hamster, honey bear hamster. They are the most common first pets and are the most personable ones as well. Once you tame your hamster, they tend to stay tamed. With the smaller breeds this is not necessarily true. Personally, I will stick with the Syrian. There is also more of them to cuddly since they get to be about 6-7 " big. :)
