Hamsters are very little animals. They actually live in the dessert but when you have a hamster you will have to put it in a cage. Hamsters don't drink a lot, so if your hamster doesn't drink a lot don't worry. If you don't know how to care for a hamster then it would be handy to buy a hamster book, because these books contain a lot of good information. It is important that you take good care of  your hamster(s).
