our male cat was a very dominant tomcat and had never been outside (it probably didn't help we had 2 female cats inside as well). he spreayed EVERYWHERE so we got him fixed and while this did cut back on the sprayings it didn't stop it all together. once a cat starts it is really hard to stop. it is a good idead to get them fixed long before they get to that stage
The cats might spray, but this will depend on if the cat had already developed a habit of spraying before being neutered. On the other hand, neutering before 6 months will normally prevent spraying, although it is still possible for this to happen.
No, fixing cats will not stop the behavior. Male cats use spraying to mark their territory. They're very competitive & protective about what is theirs & will happily say so. One male cat, alone, in a household is fine & usually not a problem. But as soon as you introduce another cat, male or female, spraying can begin. It's a risk & why I've avoided adopting a companion for my pet. I'm afraid he will ruin my walls & furniture. It's happened before & I'm not willing to risk that kind of smelly, eye-watering destruction again. As much as I enjoy having cats around, it's a very nasty problem once it starts. Just not worth it. :(
