Hamster attack

Question
My hamster, Butter, was in an attack. She was bitten or scrached by 2 month old hamster, Peanut who is twice-no three times her size. I am worried because I just got her today.  

Answer
Are these syrian hamsters? If so they cannot be kept in the same at all, and that is the reason they got into a fight in the first place. Syrians are never to be kept together, and are only together in pet stores because of their age. When they mature they become territorial and fight tankmates. Please buy a separate cage for the hamster if they are syrians, and as long as the girl in not bleeding heavily and the wound scabs up in a few days, she will be fine.
