I need help! My best friend has two neutered male cats who have begun spraying in his shop. He has had them for years and they never did this until new cats moved into the neighborhood.We will have to get rid of them if we don't find a way to stop it. Any suggestions?
I think they are letting the new cats know what's theirs. "This is mine, you stay away." I think it's like a dog, they are "marking" their territory. There are products out there to help, check with your local pet store. My adult male cat started spraying when our little female rescuee had kittens last spring - 6 of them! So I bought a spray at the pet shop to spray over the spot where he had marked (after I cleaned the surface, of course) so he wouldn't remark. And I gave him extra attention to reassure him. But that was due to introducing new members of the household. That was clearly a case of stress/feeling threatened by the new pets. But in the neighborhood? That sounds like "Mine, you go away" to me.
Sitee is absolutely right. Male cats spray to mark their turf. Sounds like your cats are threatened by the new guys on the block. Nuetering male cats before they start spraying often keeps them from ever doing it, but as you have experienced, not always. Pet store products can help, and so can a lot of love and reasurrance from you. Also, they might work it out on their own as they get used to the other kitties being around, but I wouldn't rely on that solution. The good news is, neutered males' urine is does not smell as strong as non-nuetered males. Imagine if they weren't fixed! Peeew!
