Why is my hamster's bottom swollen?

Answer by  tofuturk (581)

Male hamsters genitals are very big at maturity. Females genitals swell when ready to mate. If the swelling looks unusual it could be wet tail that needs vet treatment.

If you have a female hamster, she may look swollen if she is pregnant. It could also be a tumor, abscess, or rectal prolapse. Some of these conditions can be very serious if not treated right away. If you are unsure, or your hamster appears sick, you should take her to your vet.

It could be his testicles because most male hamsters tend to look this way. I know this because me and my two best friends all have hamsters and they all have something that looks like this. As far as i know it is NOT an infection because they've all lived.

This could be caused by a couple of things. If it is a young male, it could just be that the testes have not dropped yet. If the bottom looks inflamed and irritated or red, it could be caused by an infection. Ensure the hamster's cage is clean and consult a small animal vet if the problem persists.

If it is a girl, then your hamster might be in heat or ready to mate. Otherwise, you might want to ask a professional or look it up on Google.

It could be any number of things. If living with other hamsters, it could be a bite that has swollen into an abcess. It could be a tumor, rectal prolapse, intussuseption (abnormal intestine), or severe constipation/diarrhea. Some of these conditions are easily treatable, some are dangerous. Please take your pet to a qualified exotics vet asap for an exam.

If your hamster is a male it is probably his testicles. When it gets warm outside or the hamster has just come out of a warm next his testicles will look larger. If it is a female or there is any discharge (blood, pus, etc) then your hamster should see a vet.

Check its cage. A normal cause of this is its sitting in a dirty cage that needs to be cleaned. After a few days it should go down.
