Whats wrong near my hamster?

so i have 2 male hamsters and they are in like peas in a pod cage, they are pretty old maybe 2 years or so. and on one of them his "butt" is huge. they are both cuddly toy bear hamsters.
Answers:    Its probably his testicles. Females have a much smaller behinds because they don't have that.


I meditate the "butt" you are talking about are his testicles (I know, it looks like a big butt doesn't it!). Are you certain you have *two* males living together? The other one could be female. Make sure you aren't on the process to being a hamster grandparent!


Guinea pig's teeth are too long. Need counsel?   My rat like to verbs my teeth near his mouth.  Is this ok?   If i would take a hamster..?   My pet mice sleep for short time afterwards stirring?
