Ok, I've got a question. I told a guy at work I'd ask around. I have my opinon of what's going on with his cat but let's see what others say & if you have any help I can tell him. I myself have never had a problem with a cat going outside of the litter, but his cat has started to. I guess he has just a couple of time sprayed (& I say sprayed because he is geitting it all over the bathroom door in thier basement). This particular cat had crystals in his urine a couple of years ago & a change in diet has helped with that. I asked about changes in the house & the guy at work said one of his sons just moved back into the house. Then we talked a little more & he said the cat was drinking more & urinating more in general. (which leads to my opinon that he may have something medical going on) I explained that the cat should be taken to the vet to make sure he wasn't having some sort of problem and said I would ask around for ideas to stop him from spraying, so anyone got anything that's worked for them?
