How to Get Cat Pee Smell Out of a Couch (5 Solutions)

Although cat urine is a strong odor, there are several easy ways to remove it from your couch. These methods are safe for your upholstery but tough on smells. You probably have everything you need for some of these methods right now.

2. Natural Vinegar Solution

Pet owners sometimes prefer natural solutions rather than purchasing cleaners. Vinegar is a safe and natural cleaner that has excellent odor-eliminating characteristics. The reason vinegar is successful against cat urine is that it helps kill off the bacteria that are causing the foul odors, rather than just trying to mask the smell.

Mix together three parts of warm water to one part of white vinegar and pour it on the pee stain. After letting it sit for 10–15 minutes, you can dry the area with rags, paper towels, or a wet vac. You may need to repeat the process several times for maximum effectiveness.


3. Baking Soda

Baking soda is known for its odor-killing properties. Most people use it to combat the odors coming from their fridge, but it works just as well for removing the cat urine smell. And since it’s versatile, there are several ways for you to use baking soda for cat pee.

The easiest method is to simply pour the baking soda on the stain and let it sit for a while. It will absorb the odors and you can vacuum it off after. But if that’s not strong enough, you can mix the baking soda with vinegar or hydrogen peroxide. Make a paste of the mixture and apply it to the stain. Let it sit until it’s dry. Then, vacuum off the remaining baking soda, and the urine odor should be gone.


4. Hydrogen Peroxide

Most people already have hydrogen peroxide in their medicine cabinet, making this a very easy solution to implement. Hydrogen peroxide is antibacterial and great for removing stains. Just pour it on the pee stain and it should disappear, along with any associated odors.

If the stain is particularly stubborn, you can mix the hydrogen peroxide with some dish detergent. Use a brush to scrub the solution into the fabric of the couch. After it sits for a while, use cool water to rinse everything off before blotting it dry.


5. Automatic Carpet and Upholstery Cleaner

These high-powered wet vacs allow you to use a carpet cleaner and the magic of hot water to repeatedly clean the affected area using the power of machinery. Make sure to use a pet-specific cleaning solution to help eliminate the odors completely.

Why Is Cat Urine So Smelly?

If you’ve ever spent time around felines, you may have noticed that their urine is particularly pungent. This phenomenon isn’t in your head. Cat urine really does smell stronger than that of other animals, especially after some time.

The smell of cat urine gets worse with a bit of age. That’s because the bacteria in cat pee decomposes. When it does, an odor similar to ammonia is released. As the bacteria continue to decompose, mercaptans will be released from the odor. These are the same compounds that provide the infamously abhorrent odor to skunk spray.

It’s even worse with older felines. As cats age, their kidneys become less efficient, which makes their urine smell even worse than that of younger cats. Male cats that aren’t neutered also have testosterone in their urine. Once again, this can increase the stench. After all, the hormones are there to signal other males to keep their distance.

Why Your Cat Might Pee Outside the Litter Box

Generally, cats do a pretty good job of sticking to their litter box and won’t often have accidents around the house. If your cat is urinating outside the litter box, there might be a deeper problem at fault.

One common reason for cats engaging in this behavior is an underlying health condition. Urinary tract infections, kidney disease, feline lower urinary tract disease, diabetes, and more can all cause a cat to urinate outside of the litter box.

Cats with arthritis can also find it prohibitively difficult to use the litter box. In such a case, switching to a litter box with easier entry might solve the problem.

But sometimes, it’s just a behavioral problem. If this is the case, you’ll need to take action quickly and determine what’s causing the behavioral change. For homes with multiple cats, it could be something as simple as competition over the litter box. Remember, you should always have enough litter boxes for each cat in the house, plus one additional. So, for homes with three cats, four litter boxes should be available.  Finally, proper sanitizing with an enzyme cleaner after accidents will help eliminate repeat accidents.
