A few weeks ago I noticed that my cat has been attacking his tail. He has been biting it to the point where most of the fur is gone from the tip and it was bleeding....but that didn't stop him. He kept at it and was crying as he was doing it. I took him to the vet where they took X-rays of his tail. The X-rays came back fine and the vet cannot figure out what the heck is going on. We have bandaged up his tail and he has left it alone with the bandage on but once I take it off, he's right after his tail again, and he's really hurting himself. I don't know what to do. He can't go on for the rest of his life with a bandage on the end of his tail but that's the only way he leaves it alone. This is so strange and I don't know what to do......Can anyone help???
