Cats make incredible companions, but when they have accidents, the smell can linger. Fortunately, there are some steps you can take to eradicate the smell of cat urine from your carpet. By carefully cleaning up the urine and then working hard to deodorize the area, you can remove the smell of cat urine from your carpet and home. This method can be done at any time, but it works best if it is done as soon as possible after the accident.

Cleaning Up the Urine

Blot up the urine if it's still wet. Using a paper towel (or a cloth towel that you can discard), press down on the spot where your cat urinated to blot up the liquid. Repeat this method until the area is mostly dry.^{[1]

3
Create a vinegar solution from equal parts vinegar and water. If the enzyme product did not completely remove the smell, you can try using a vinegar solution. Mix equal parts of white vinegar and water and apply this to the affected area. Vinegar will further breakdown the smell and help it to dissipate.^{[5]

Pour a mixture of 0.5 cups of hydrogen peroxide and 1 teaspoon of dish soap on top of the baking soda. Hydrogen peroxide mixed with baking soda with create a foaming action that is very effective at removing odors. Create a solution from 0.5 cups (120 ml) of 3% hydrogen peroxide and 1 teaspoon (4.9 ml) of dish soap. Pour this solution over the baking soda and allow it to foam.^{[10]
