hamster with bump around butt

Question
Dear Kelly,
Please help me. I have a long haired black bear hamster and he has a big bump around butt and hind legs. I have no other hamsters but sometimes he bites himself while cleaning himself. The bump is big and black and kind of red. It is getting worse everyday. It is Sunday is going to vet on Tuesday too late?



        Help!,

Answer
Hi Jasmine,

It sounds like your hamster may have an abscess (or possibly a tumor, but most tumors don't grow that fast).  An abscess can burst and cause an infection, so you're right to take your hamster to the vet.  If Tuesday's the soonest you can get your hamster to the vet, that's fine.

If you have any other questions, please feel free to ask.
