Things You'll Need
Dish soap (no ammonia or citrus)
3 percent hydrogen peroxide
Laundry detergent (with enzymes)
If your cat has frequent spray or pee spots, you may need to discuss with your vet about additional options for stopping this activity in your home.
All products used on fabrics and carpets should be tested to ensure they are safe with your particular materials. Color fastness varies. Locate cat stains when the room is very dark by using a black light. The main cat spray removal spray is the vinegar and water mixture. Baking soda is commonly used to deodorize and should be safe on its own as a regular carpet deodorizer when you vacuum. Consider getting a cat pheromone plug-in diffuser to pacify your cat.
Cat spray is an unpleasant reality with some cats. There are a lot of reasons a cat may spray, and a visit with your veterinarian is a good place to strategize solutions. However, correcting the problem may take some time, and living with cat spray odor all over your home won't allow you to wait. There are some quick and easy recipes for cat spray odor removers that can be made with ingredients you probably have on hand.
Mix 2 tsp. of laundry detergent with enzymes with 4 cups of water. The enzymes digest parts of the urine and will stop the odor. Make sure your laundry detergent doesn't use ammonia or bleach as ammonia can smell like urine to a cat and the odor can actually cause them to urinate (or spray) in reaction. (This mixture may affect dyes in carpets so test in an inconspicuous place for color fastness on your carpet before using. It also is excellent as a first-step cleanser for hard surfaces.)
Mix 4 cups of white vinegar with 4 cups of water and pour both into your spray bottle. The acidity of vinegar neutralizes the ammonia of cat urine and it is also antibacterial and kills any micro-organisms. (Cat spray is cat urine sprayed about 8-inches above the floor.) This mixture should be used the most often and it is generally safe on fabrics and carpets, but test for color fastness. You can use this mixture on its own or to disinfect the area after using the mixture in Step 1.
Deodorize by liberally sprinkling baking soda on fabrics and carpeting once they are dry. Most cat smell is held in soft fabrics and carpets, but baking soda draws out odors. Enhance the drawing-and-deodorizing effect of baking soda by applying an activating mixture to the dry baking soda. Mix 1/4-cup of hydrogen peroxide with 1 tsp. of generic dish soap (no citrus- or ammonia-based products).
Wearing rubber gloves, combine the dry baking soda with the moist peroxide and soap liquid mixture. Apply directly to the stain site by kneading the ingredients together and working them into the stain area. The mixture should be lightly moist and the soda should dissolve from the peroxide. Test your peroxide mixture for the color fastness of your carpet and fabrics before using in a highly visible location.
