Because cats are territorial in nature, they sometimes spray urine to mark their domains. However, as your cat ages or if it has an underlying medical condition, it can spray often, which can become problematic. Simple home products can help remove your cat's urine odor. Acting immediately after spotting your cat's accident will help prevent smells from settling into your furnishings or carpet. If your cat continues to excessively urinate after treatment methods, visit your veterinarian.

Combine 1 c. of white vinegar with 2 c. of warm water. Put the solution into a spray bottle and spritz the affected carpet. Use paper towels to blot the moisture after spraying.

Mix 1 tsp. teaspoon of dish soap and 1/4 c. of 3 percent hydrogen peroxide. Sprinkle a light layer of baking soda on the carpet. Use the peroxide solution on top of the baking soda.

Take your mattress off your bed if your cat has soiled the mattress. Blot the area using paper towels.

Use the vinegar and water solution provided for carpeting. Apply the baking soda. Spray on the hydrogen peroxide and dish soap mixture and work the mixture into your mattress using a toothbrush. Blot the mixture.

Set your mattress outside to dry in the sun. If this isn't possible, use a hair dryer to help facilitate the drying process. Place your mattress back on your bed when it's dry.


  • Do not rub the urine into your furnishings or carpet. This will result in the odor spreading and setting in.

    Don't use cleaning products containing ammonia, which can replicate the scent of cat urine.

    Dried urine stains require enzyme cleaners to help break down the odor causing bacteria. You can purchase enzyme cleaners at pet stores.
