I have a 17 year old male cat named Chip. He started peeing and pooping all around the house. He seemed lethargic, so I took him to the Vet, thinking that he had a urinary tract infection. They gave him a 2-week injection of anti-biotic. After two weeks, he was still pooping and peeing all over. So, I got some Batryl from the Vet, and have been giving him that for a week now. I've had him confined in the utility room for several days, where he has been peeing in the litter box.

So Saturday, I cleaned the entire downstairs carpets very well, and left him in the utility room one more night. Sunday morning we left him out, went out shopping, and when we returned, he was laying on top of my son's toy box with a load of poop about 2 feet from him. So, back in the utility room he went.
The Vet assistant said that sometimes these infections can take weeks to subside. The Vet herself said that if the problem doesn't subside soon, then we can take x-rays, and perform some tests to see if we can pinpoint the cause. But here's a couple of questions I have concerning this:
1. Can a urinary tract infection case a male cat to poop outside the box?
2. I know cat's love the heat, especially my Chip who lays in the hot baywindow with the sun beating on him But what's a realistic "high" temperature to keep him at? The reason I ask is that the utility room gets a bit warm.
-Thanks

He's trying to tell you something. What has changed around your house? How old is your son?

My son is over 4 months old, so it's nothing to do with him. One thing that is different is that I had the Vet (and about two assistants) give my cat a trim, because he had matted fur in places, mostly on his stomach, where I couldn't brush. He really didn't take it too well, and I felt so bad for him, listening to him yelling in the next room. Next time I'm going to have him knocked out before doing anything like that! Plus they can work on his teeth at that time too.
But nothing has changed recently. He definitely seemed like he had a urinary tract infection, and he was very lethargic, until we started him on the anti-biotics. He seems much better now, but still, pooped outside the box.

Have you tried a different type of litter? Sometimes, something as litter can cause a difference. Or if you have not changed litter, then perhaps that would be something to try something very soft because of his age. And the actual litter box? Does he have any difficulty/awkwardness getting into or out of it?

I'm aware that some cats may dislike certain types of litter. But that's not the problem He goes inside the box when I keep him in the utility room. He did his duty in the box for about 2 days while in the utility room, I cleaned the carpets, let him out, came home, and there was poop in the living room. I even put a second litter box in the garage, and he didn't even make an attempt to use it.

I can't add anymore than what people have been posting, but I wanted to say your subject line is hilarious and witty. :-)

Could it be that your cat now associates the box with the pain of the UTI? It may take longer than a couple of days in the utility for him to lose that association.
