Question
my hamster got really fat   she is really mean if i touch her she bites me i cant even play with her but if i play with her she will bite me

Answer
Has your hamster been around a male within the last month? If she's not pregnant it's normal for a hamster to get big. Hamsters get to be about 6-7 inches long. If she has gotten bigger over night then she may be sick or constipated, if you give her a strawberry it might help her move anything out of digestive tract along. If that doesn't solve it then I would really take her to a vet to get looked at.
