Instructions
Observe your pet for spraying behavior. Before a male cat sprays, he raises his tail straight up and moves the tip from side to side right before releasing urine. His behind will usually face a vertical object, such as a furniture leg or wall, during the spraying action. Since he may release only a few drops at a time, the release of urine may not be obvious. (See Reference 1)
Inspect the wall and furniture in the room where you suspect the cat sprayed. Look for diffuse droplets of moisture in vertical spots. (See Reference 2)
Turn the lights off and use a black light to detect dry urine stains. Cat urine will glow under a black light. If you see spots of urine in a vertical area, the cat is spraying. If urine is on the floor, the cat is urinating normally. (See Reference 3)
