neutered tabby spraying

Is there any way to stop a tomcat that has been neutered to quit spraying EVERYTHING in the house?  He is the only one of 3 toms and a calico that does it.

He might have medical issue. Take him to the vet to be checked out.

The use of the word "tom" means that the cat is not neutered. Once neutered he is no long called a "tom". If your cat was neutered late, meaning after sexual maturity, and was already spraying then it is a learned behavior. If he never sprayed before and only recently started, a vet visit is the very first place to start. Then, look at possible stress causing issues in the home such as not getting along with one of the other resident cats, stray cats outside the home, not enough litter boxes, the type of litter and litter box locations. for your cat.
