Instructions
Catch him in the act of spraying. When a cat sprays, he will back up to a surface-like furniture-hold up his tail and spray urine in several short bursts. Cats who are simply urinating will squat. Observe your cat for this behavior to confirm he is spraying.
Scan with a black light. Turn off the lights in your room and run a black light around vertical surfaces, such as couches, chairs and blinds.Cat spray will glow under a fluorescent black light. Sprays will show up as a ̶0;splat and drip̶1; pattern. Look around the perimeter of the room at about 6 to 12 inches above the floor.
Use your nose. The smell of cat spray smells terrible. You will likely be able to tell that your cat has sprayed simply by walking into the room.
