This results in it having hand like features. Hamsters do have tails but it is extremely short. One of the most fascinating features of a hamster is its' ability to store food in cheek pouches. When these pouches are full it can double the size of the head. When the hamster wants food or it finds a place in the cage to hide it, this rodent then pushes its' cheeks forward with its' little hands for the stored merchandise.
Hamsters have teeth and they can bite.
This biting usually will subside when the hamster and the owner become use to each other. Also, hamsters as a rule do not mix well with other hamsters. It is difficult to introduce a new hamster into another hamster's cage. A technique that may work is to totally clean out the cage with the original hamster and change around the toys and dishes and then introduce the new and the original together. Again caution should be taken and a watchful eye must be kept on the hamsters to make sure they do not kill each other.
