Your cat may urinate in inappropriate places because of a behavior or medical issue. Your cat may also avoid a dirty litter box. Odor from cat urine is very strong. Your cat may return to that area to urinate again and again. To eliminate cat urine odor, start by blotting up as much urine as you can with paper towels. Baking soda will help absorb odor. Use a commercial enzymatic cleaner. This breaks down the urine and destroys the odor. Cleanany washable items by themselves in the laundry in cold water with an enzyme detergent. You can clean carpets with a rug-cleaning machine. Use cold water to extract the urine since hot water can set the odor. Use a pet-formula detergent in the machine. And of course, address the reason your cat urinated inappropriately in the first place. For more information, contact your San Leandro, CA veterinarian.
