So, I have this cat. We adopted him in 2007. Story time:
You know how with many cats, if you scratch their back right around the base of the tail, they will start licking themselves? That is how this problem started out. You would scratch his back, and he would lick himself. Then you would touch his back, and he would lick himself... a lot.
It has progressed to the point where the licking has turned into a violent, uncontrollable spaz attack. It sometimes even happens when he's just SITTING there and nothing touches him. He will roll over onto his back, thrash and flail all over the place in this, biting, scratching kicking pile of crazy ass cat. A lot of the time he pees everywhere while he is doing this. If he starts to spaz out on a table, he will roll off the table and not even pause from this... I don't even know what it is. He'll hit the walls, he flies across the floor on his back, it looks like some exorcist bullshit. Several months ago, he was asleep in my sister's bed and she didn't know it. She went to turn over in bed, accidentally touched him, and he started doing the thing - except she was in the way and he bit THROUGH her thumb. His tooth went in one side and came out the other. This was completely accidental, he is not by any means an aggressive cat.
Whenever he's not rolling around spazzing out, he's the sweetest cat ever. Very needy, almost too needy. If you are standing near a table, he gets up on his hind legs and gives you a hug. He always wants to be held and petted and tunnel under the blankets with you. But I feel terrible because I'm afraid to touch him or let him sleep in the bed with me because he's already spazzed out on my lap and gotten his claw caught under my skin and ripped a chunk out.
We've taken him to the vet for this problem and they literally did nothing about it. They had nothing to tell us, but tried to charge us $400 for the visit anyway. I don't really know what else to do, and I've done countless google searches trying to find someone else with a similar problem.
Please, do you have any freakin' idea what's wrong with my cat? I just want him to stop rolling around and peeing everywhere.
