The smell of cat pee is never going to go away until you properly clean it thoroughly. However, if the stains and messes that have caused the nasty odor are going to take some time to clean up (say, if you need to pull up and throw away carpet, padding and seal the floorboards underneath) then there are few things you can do to try and temporarily subdued the smell while your cat-pee-cleaning project is underway.
1. First, you need to air your home out every day until that stain is appropriately and thoroughly cleaned up. Open up the windows, get your fans going and circulate that urine soaked air out of the house.
2. Find any washable or loose items that have been peed on, and either wash them according to the methods in this article or just throw them away if they’re unimportant or so far gone that you don’t want to deal with them. Getting rid of as much of the affected stuff as possible will help.
3. Use a pet stain carpet deodorizer to vacuum your carpets every day until you get the source of that odor eliminated.
4. Use odor-eliminating plug-ins to temporarily work over the scent of cat pee until you have cleaned up the bigger problem. This isn’t going to work long-term because again, the big problem here is whatever is stained with urine, whether it’s a sofa, carpet, flooring or a pile of laundry that the cat peed on.
5. Keep your cat’s litter box clean - scoop it every day and add a layer of fresh litter over the top afterward to keep things as fresh as possible.
