I have a female cat, who is 4 and a half years old and spayed and is spraying the sofa and numerous other places. She was spayed only about 6 months ago. The reason she wasnt spayed at an early age is because the vet I took her to said she had a heart problem and not to because it was too risky, but it turned out she didnt have a heart problem or she grew out of it. She has never had kittens either. Has anyone ever had to deal with a female cat spraying? She did it before she was spayed and quit for a while after she was spayed. I have bought Feliway spray, and Feliway plug in and extra litter boxes and so far it hasnt helped. I think I have figured out why she is doing it but dont know how to get her to stop. We have another female cat that is my daughters and it seems like all the places she has been this cat has sprayed. She doesnt like this cat, they dont fight and the other cat pays her no attention but they stay their distance from one another. I think I know what the problem is but dont know how to get her to stop this behavior. Any ideas? I have bought enzyme cleaner, Natures Miracle and cleaned the spot where she marked the sofa, but I'm getting rid of it in a couple of weeks for a new one, you think I should spray the new one with Feliway right away when it comes? I was so hoping she would stop the marking when she was spayed and she did for a while and then started up again. Any ideas?
