What's wrong with my rat?

I can only speculate this may be a tumor, A vet would have to diagnose his to see where you stand.

A friends rat developed a tumor, risk of removal was too great, Wasn't in pain so his pet lived out is life wih it.

Last 6 months just caused mobility problems so meant catering to the rats needs. seemed to be happy though, she was well cared for and loved.

It is mammary tumor, Common with females. Often hereditary, not a result of improper case. Having it excised is about $700. But, many rats are near the end, sadly, when this happens.

Tumors are quite common in rats. It looks like a mammary gland tumor. A vet can likely remove it. Otherwise it will continue to grow. I have seen them grow almost as large as the rat itself.

We can't tell you what is wrong. Neither can we tell you what treatment will cost, though I can say with some certainty that something that size will require surgery to be removed and that is probably going to be at least several hundred dollars. And whatever you do, for god's sake do it soon. That thing is large enough to be causing some serious discomfort. I can't imagine leaving it so long that it got to be that size. Something small might have been fairly cheap to deal with. Now, it's going to cost even more, if it can be dealt with at all.

It`s probably a tumor. Rats have been bred for developing tumors so that science can then attempt to develop new cures, etc. I`m pretty sure you will not want to spend the money. Just chalk it up to experience and try to find a better strain of rat next time. Wild rats, breeding wise, are your best bet. Rats do make excellent pets. Best of luck.

It just realized it's a pet with a name. Kind of like a beached whale. Let it go.
