How do you get a neutered male cat to stop spraying inside the house if three neutered males are present and it happens when everyone is asleep?

Answer 1

There are many reasons this could be happening. If you brought another cat in (whether it's male or female) then the two you have at home aren't going to like it and are gingerly marking their territory. You can go to the vets and ask questions and they do have some good sprays to use. Meanwhile, clean up the spray as usual, then mix vinegar in warm water and soak a clean cloth in it, ring it out and rub on the surface, then pat dry. This will help to break-down the pH level in the urine. Good luck

Answer 2

Make sure each cat has their own territory by providing multiple litter boxes, scratching posts, and resting areas. Clean any sprayed areas thoroughly with an enzyme-based cleaner to remove the scent. Consider using synthetic pheromone diffusers to help reduce stress and territorial behavior among the cats.
