Have you ever had an issue with tumors?

Oh wow!!! I can't believe it has that stuff in it! I hope Mazuri doesn't :cool:

I wondered if that affected them at all. It makes sense. My sister kept her hairless solely on carefresh. She started getting those abscesses/tumors at hardly a year old. It was nuts. They didn't get awful till she was old.

I've never had any problems with tumors in my rats, so I consider myself very lucky. :D Sorry to hear about your sister's hairless' problem. Poor ratty. My hairless girl, Cher, has been very healthy and no tumor problems. *Knocks on wood*

Tumors are definitely an inherited problem, though. If you have a female (or even male) with tumors, avoid breeding it to keep from passing the gene on in their lines. ;)

I have also had a few older females get tumors. I have not had any on males. Im not sure how old they were but I know they were over 2 years old.

Does this go for mice as well. My female mice only when after having babies will develop large lumps on them. Males NEVER got them its only females and they get soo big that it affects their walking and never breed again.
