We have four cats. Three males and one female. Everyone mostly gets along, but we've had MAJOR problems with spraying/marking since the newest one joined us a few summers ago. My son rescued this rascally little orange guy - he was so tiny and so sick that the vet didn't think he would make it but, of course, he's a cat and as you can see he is doing just fine. He is such a kick and has so much personality, but ever since he's been with us, he and the other two males are just spraying everywhere and destroying our house. Sometimes one of them will even pee on a bed right in front of the person in it! Drapes, furniture, counter-tops, carpet - doesn't seem to matter what or where, and while the orange one seems to be the most active, the two other males are by no means innocent. DH has (understandably) had it with the mess and the smell, and the orange guy may have to find a new home soon. I've researched the problem and found suggestions about changing litter boxes, using a new kind of litter, using a black light to track down all the spots and neutralizing them with white vinegar and Nature's Miracle. We've begun taking these steps, and we're also going to take him to the vet to ascertain that he doesn't have a UTI although we're 99% sure already that this is behavioral and not medical. The situation does not bode well for this little fellow and I feel terrible about it. We've never booted an animal before and I don't think the chances of finding a good home for him are all that high. Has anyone else ever successfully dealt with this problem?
