Natural Ways to Get the Smell of Cat Urine Out of Carpet


Time is of the essence for getting cat urine odor out of carpeting. Chances of removing the odor completely are greatly reduced if the cat's urine absorbs into your carpet padding. Removing all traces of odor to prevent territorial remarking from the cat or other felines in the house is critical. Two veterinarian-recommended natural options are available to remove cat urine odor from the carpeting for those seeking to run a green household.

Know Your Enemy to Defeat It

  • The key to removing urine odor from carpeting naturally is to understand the chemical makeup of the offending fluid itself. Healthy cat urine is sterile and was once used as a cleaning product. It is also an ammonium concentrate -- germ-free as it may be, it stinks. Urine is comprised of water, salt and waste removed from the bloodstream by the kidneys. As the feline's body breaks down proteins and nucleic acids, it releases nitrogen into the bloodstream. Excess nitrogen binds with hydrogen, producing ammonia. The kidneys filter out this natural byproduct, creating urine, which the cat, unfortunately, might pass onto your carpeting. Natural products that target ammonia are necessary to remove the cat's urine odor.

Household Products

  • Most green households already know the cleaning power of natural products, such as white vinegar, club soda, baking soda and hydrogen peroxide. Clean cat urine odor with these products as well by immediately placing either paper towels or rags on the carpet where the cat urinated. Press down on the towels to draw up any loose urine from the carpet. Mix a solution of 1/2 white vinegar and 1/2 water. Saturate the carpeting with this solution. The white vinegar binds to the ammonia to remove the smell. Once nearly dry, blot the solution or vacuum up with a water-extracting vacuum. Mix 1 tsp. of liquid dishwashing soap with 1/2 cup of 3 percent hydrogen peroxide. Pour baking soda over the urine spot on the carpeting, pour the dishwashing liquid/peroxide mixture on top of the baking soda and scrub the mixture into the carpeting. Allow this to dry and vacuum it up. You can also use club soda and dish soap instead of white vinegar if you prefer.

Enzymatic Products

  • Many veterinarians agree that removing cat urine odor from carpeting is more effective with a natural enzymatic cleaner. Veterinarian Marty Smith explains on Pet that, "these natural organisms actually 'eat away' or digest the odor-causing bacteria, permanently removing them from the deepest fibers in your carpet and the padding below." Smith also states that the natural enzymes and bacteria keep digesting the urine until there is nothing left for them to feed off of, completely removing the cat's accident from your carpeting. These natural enzymatic cleaners come in granule and liquid formula. Granules can be used to soak up extra urine not absorbed by towels, followed by the liquid cleaner (if necessary) to remove the remaining odor and stain. Natural enzymatic cleaners can be purchased at pet supply stores and online.


  • Regardless of the natural method used to clean up the cat urine and its resulting odor, do not punish your cat for using your carpet as its litter box. The most common reason a cat urinates outside of its litter box is because it is ill and it is trying to tell you that something is wrong. If your cat suddenly turns to your carpeting to relieve itself, take it to the vet immediately for medical evaluation.
