If there’s a lingering cat pee smell on a mattress, carpet, or another kind of flooring, try using an enzyme cleaner. Enzyme products are made to break down biological matter like urine, so they’re great at getting rid of pee smells. The one I really like is called Bac-Out.

Another thing that you might not think of is cleaning the walls around the area. If you've had a pet spraying somewhere, washing the surrounding walls can go a long way towards removing the odor.

If the above methods aren’t working, my next suggestion would be an ozone machine. It’s basically the big guns for any odor, and it isn’t terribly expensive—you can buy one for about $100 on Amazon. To use it, you plug it into the wall and let it run anywhere from 15 minutes to an hour, depending on the size of the space. Afterward, you air the area out really well, and that process should kill all odor. Just make sure there are no people or pets in the space while the machine is on because it can be an irritant to the lungs.

If the urine smell is in the air, try leaving bowls of vinegar around the room, and wash all surfaces with pure white vinegar. It will smell strongly like vinegar while you’re cleaning, but once that smell fades, it also tends to take all bad smells with it.
