How to Clean Cat Urine & Spray

Trying to clean stains and the smell from cats urinating on carpets is tricky business but removing carpets, padding and floor boards is not an easy or practical thing to do for many.

Here’s a handy tipsheet to help you get the job done. Next you’ll find tips and recipes for dealing with spray from adults.



Method #1

1 16-oz. bottle Hydrogen Peroxide
1 TBS Baking Soda
1 tsp dish detergent (liquid)

Method #2

Method #3

Method #4

Removing From Washable Items

If your pet keeps returning to a spot to do it again, it’s because she still smells it from before and this will trigger her to do it again. You must remove the odor completely before she’ll stop.

If the above tips don’t stop the behavior, try pouring a box of baking soda over the area and leave it sit there for 30 days (!). You could also try setting a bowl of vinegar right beside the spot, this may deter your pet and break the behavior.

Please Note: Cats urinating in the home could be a sign of a medical problem (such as kidney or bladder infections). Check with your vet.

If you’ve ever had a tomcat stroll by and spray around your basement window or front door, you know what a stink that is!

This is pretty potent stuff and the smell is not something that dissipates easily. The quicker you wash it up, the better chance you have of avoiding a repeat performance (the spray from one can trigger more action from others).

Here are a couple recipes I have on hand for both indoor and outdoor messes along with some deterrent suggestions.

Recipe #1

This is to tackles messes outside the home, be aware that this treatment may affect lawn and plants that the solution comes in contact with. If it’s on surfaces like the house, windows, patio, sidewalk, deck, etc., scrub the mixture in with a brush before rinsing off with clear water.

After washing the area, spread a thick layer of baking soda over the spot after the surface is mostly dry or a mix of 50/50 vinegar and water. This will help dispel odor and (hopefully) deter future incidents.


Recipe #2

This recipe is to tackle jobs inside the home, test an area for colorfastness first.

1 16-oz. bottle Hydrogen Peroxide
1 TBS Baking Soda
1 tsp dish detergent (liquid)


There are various plants and methods you can use to try and deter the neighborhood prowlers from your property, a few suggestions:

A very effective deterrent is a motion activated sprinkler, they’re not that expensive and animals will scat as soon as the water starts. Each time a critter comes into range, the sprinkler will automatically turn on and soak it with water. If you can’t find one locally, they are listed on Amazon.

Many folks try to discourage these animals from entering their yard not only to prevent spraying, but also to protect their own house pet from being exposed to nasties like roundworm eggs and the Toxoplasmosis parasite (and to avoid finding feces in their garden). If you find keeping them off your property is impossible, consider planting catnip [1] in a far corner away from where you want them, most will happily stalk the area and hang out there ;).
