My cat is spraying indoors – how do I make him stop
Unfortunately, if you have other cats and have not neutered your male cat and he is close to a year old or older, the spraying will be tough to stop. If he is not neutered, you can try neutering him (though generally you need to do this when they are younger).If he does not stop spraying after being neutered, the solution in this article is actually a highly effective method that works to stop spraying for both males and female cats that have been spayed/neutered and still mark their territory. A lot of times the cats need a room to themselves to feel safe and secure since they are not secure in their current environment. You can try giving your cat an enclosed room to themself and allow them to have their own "cat room" for several months (although it can take longer depending on the cat). After you have given your cat a few months to relax and become comfortable, the spraying should stop completely.
