Here are a couple recipes I have on hand for cleaning both indoor and outdoor messes along with some cat deterrent suggestions.
Cat Spray Cleaning Recipes
Recipe #1
This recipe is to clean cat spray outside the home, be aware that this treatment may affect lawn and plants that the cleaner comes in contact with. If it’s on surfaces like the house, windows, patio, sidewalk, deck, etc., scrub the cleaner in with a scrub brush before rinsing off with clear water.
- 3/4 cup Original Tide (or any laundry detergent with enzymes)
- 1 quart hot water
After cleaning 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 the cat from spraying there again.
Tips:
- You could also try spraying the area with a garden hose then pouring straight vinegar around the spot, this might just do the trick for you (may also affect plant life).
- If you can’t clean the spray immediately, try to at least throw a bucket of water on the area to dilute the urine until you can get to it.
Recipe #2
This recipe is to clean cat spray inside the home, test an area for colorfastness first.
1 16-oz. bottle Hydrogen Peroxide
1 TBS Baking Soda
1 tsp dish detergent (liquid)

Cat Deterrents
There are various plants and methods you can use to try and deter the neighborhood cats from your property, a few suggestions:
- Citrus rinds tossed in the flower beds (orange and lemon peels).
- Coffee grounds.
- Fill flower beds with a thick layer of pine cones, rocks and cedar chips. If cats can’t dig in the dirt, they’ll look elsewhere.
- Plants: Cats aren’t fond of Lavender, Marigolds and Chamomile. Also try plants that have strong scents, cats don’t tend to like them.
A very effective deterrent is a motion activated sprinkler, they’re not that expensive and cats will scat as soon as the water starts. Each time the cat (or other critter) comes into range, the sprinkler will automatically turn on and spray the cat with water. If you can’t find one locally, they are listed on Amazon.
Many folks try to discourage cats from entering their yard not only to prevent spraying, but also to protect their own house cat from being exposed to nasties like roundworm eggs and the Toxoplasmosis parasite (and to avoid finding cat feces in their garden). If you find keeping cats off your property is impossible, consider planting catnip in a far corner away from where you want them, most cats will happily stalk the area and hang out there

Did You Know:
- Cats spray for a variety of reasons including marking territory, proclaim mating intentions, as well as a symptom of stress and anxiety.
- Both male and female cats spray, neutered or not, but it is mainly the un-neutered male cat that sprays.

We had a problem with neighboring cats for years, since we are allergic we couldn’t get our own one as a deterrent. For water-wise reasons we put a mulch of bark chips on our garden and that was the last we saw of the cats – they didn’t approve of the spiky environment! Now we keep our garden topped up with bark chips, available from our local nursery.
We had a very old stray we took in that ended up blind. He missed the liter box a few times and went in the corner of our basement on the carpet. I was able to lessen the smell tremendously using baking soda and peroxide. I finally got bold and just poured full strength peroxide on our carpet. It did help. I suggest you test for color fastness first. It didn’t seem to bother our carpet, but you never know. Sure did improve the smell.
Good Luck!!
I have found that for cats that spray indoors, a great deterrent is a 50/50 mix of vinegar and water misted with a spray bottle on the attractive area. They dislike the smell and will leave the area alone.
Never, ever use mothballs where anyone or anything can inhale the smell and toxic chemical within. Very dangerous and you should never put them as a deterent for animals.
Hi Patsy, you’re right…not a great idea even though they were enclosed in fabric bags (who knows what will seep into the soil when they get wet). I removed that info from the “Cat Deterrents” section. Thanks!
