Friends, I need your help.
My eldest cat (16 years old) has a tumor on his side that is swiftly filling with fluid. My vet has never seen anything like it. Since it’s mostly harmless (benign), she doesn’t want to put him under because anesthesia and surgery would likely cause more problems than they’d solve at his age. He might not come back out of it.
The fluid has been analyzed and is made up of protein, keratin, microphages, and pigment. Nothing harmful. We’re using a fine needle aspirate to drain the tumor occasionally before it gets too big, but the tumor fills up at least half way in just three or four days. The more the tumor fills, the less quickly it seems to fill. It’s not doing anything. The cat doesn’t even know the tumor is there, really. It doesn’t hurt or bother him.
But it bothers me because I don’t know what’s causing it and my google-fu fails me in trying to find an answer.
So, does anyone have any thoughts on what could be causing this tumor? Is it diet related? Is it something else?
The cat has hypo-thyroidism, but it’s under control with his special Y-D food by Hills. Any other thoughts?
