The smell of cat urine is very strong and can easily overtake a household, despite your best efforts to cover it up.The only way to get rid of the smell is to neutralize it by breaking down the enzymes that are causing the offensive odor. While there are many commercial products out there, it's easy to mix your own all-natural solution. No matter how long ago the cat sprayed your furniture, it's still possible to eliminate the odor for good.
If the affected area is still wet, take an old rag and blot up as much of the cat pee as you can.
Fill a spray bottle with a solution made of 75 percent vinegar and 25 percent water, and saturate the affected area.
Allow the area to air dry. Prevent any animals or people from sitting on furniture while it's still damp.
Liberally sprinkle the affected area with baking soda and let it sit for 30 minutes.
Mix a solution of three percent hydrogen peroxide and one teaspoon of dish detergent. Test this solution on a hidden area of the furniture to make sure it won't leave any discoloration marks on the fabric.
Spray the solution over the areas that are coated with baking soda.
Use your fingers to massage the baking soda into the fabric.
Once the furniture is dry, vacuum the material up. If odor remains, repeat the process until you achieve the desired result and the odor is gone.
Cats will continue to pee in the same area if the odor remains, so in order to prevent future incidents, it's important to completely remove the odor. If you're unsure of exactly where the odor is coming from, use a black light, which will illuminate the area that contains the dried urine.
