Teddy Bear Hamster? A Few Questions...?

Don't not use a water bowl because they might put there whole body in there and get a disease called "Wet Tail"( I know gerbils get it maybe hamsters dont, Im not sure I will have to find out). I am getting a Teddy Bear Hamster soon! Either Friday or Saturday I am reallly excited! I am probably going to get a white one. What color is yours? Just add addtional details and tell me.
