Male cats that are unneutered usually start spraying urine when they have reached sexual maturity. A tomcat usually reaches sexual maturity between 6 and 12 months. All cats are capable of spraying and even neutered male cats may spray. However, there are several different things that you can do in order to stop a male cat from spraying.

  1. 1

    Take your male cat to get castrated; it will decrease the cat's natural urge to spray. If left unneutered, a male cat will tend to spray to mark its territory, producing a very strong odour. Early castration will in the majority of cases keep a male cat from ever spraying. Late castration may not completely stop spraying, but it will decrease the number of spraying incidents.

  2. 2

    Clean immediately any area that a cat has sprayed. Clean with a detergent that has enzymes and then spray lightly with white vinegar to keep the cat from returning to that particular spot.

  3. 3

    Keep the litter box clean and fresh. A dirty litter box will encourage spraying and using the bathroom in other areas. Cats are drawn to clean litter boxes and if you have a male cat that has started spraying, it may be necessary to change the litter box often to promote elimination habits.

  4. 4

    Give your male cat anti-anxiety medications. Many veterinarians will prescribe anti-anxiety medications for male cats that have trouble with stress spraying. Stress spraying can be brought about by multiple cat households or stress caused by relocation.

  5. 5

    Get some pheromone products like diffusers or sprays. Pheromones help to manage stress conditions in male cats. Pheromones put a friendly smell in the air that, when used in places where the male cat sprays, can deter the cat from spraying.

Tips and warnings

  • Multiple cat households are notorious for spraying issues, especially if there if there are male cats that have not been neutered in the home.
