My bestfriend has the rabbit that we got about 5 years ago. I've moved multiple times and the rabbit ended up bonding with her more, so she kept him. He lives on carefresh, eats a good pellet & hay diet with lots of fresh stuff, and was neutered at about 2.5 years of age.
The other day she called me, saying that she had found lumps under his arms that felt tumorous.
Today she took him to the vet to have them checked out. They're located directly on his ribs, on both sides, and upon aspiration, discovered that they're tumorous and could be cancerous.
Thursday he's set to have surgery to remove them.
I can't find much info online about rabbits and tumors. Is it common? Why on earth would there be tumors on his chest and on both sides? Has anyone else delt with this?
