A-Z-Animals’ Top Picks for Outdoor Cat Repellents
#1 Best Overall: Nature’s Mace Cat Repellent 1 Gallon Spray
The #1 Best Overall outdoor cat repellent is Nature’s Mace. This ready-to-use formula is both powerful and effective. Compared to other cat repellents, this formula has more active ingredients and is scientifically backed to make sure you have a product you can rely on. It is made up of natural ingredients, using a combination of scents and odors already found in nature. Nature’s mace products are biodegradable and non-toxic, which makes them safe for use around plants, vegetation, and children. You can rest easy knowing that your yard and garden are protected without the use of harmful chemicals on your plants, fruits, or vegetables.
We suggest a 1-gallon spray because this way, you have plenty to use throughout a long period. Stray and feral cats appear at different times of the year, whether it be spring, summer, fall, or winter. The spray doesn’t wash off during rain, irrigation, or normal use. It can effectively cover and repel 15,000 ft.² to protect your lawn, garage, garden, shed, or wherever you need protection from outdoor cats. This spray offers a humane solution for repelling and training cats to stay away from your home. This way, you’re protected against scratching, gnawing, or other bad behaviors. If you have a cat indoors that you need to establish boundaries with, this is also a safe formula to use inside the home for domestic cats.
One reviewer tested this product out for seven days. He faithfully followed through with the saturation as instructed for the first seven days and saw immediate results. He has had no cats in his backyard since he started using it. If you have a cat problem, he highly recommends you get this stuff! Previously, he was receiving tons of doorbell motion sensor notifications, and the majority were because cats were prancing about his home. However, his notifications have changed to only alert him of his mailman and some delivery people. Zero cats. He’s excited to keep using this and keep his home a cat-free zone.
Some reviewers said that this product smelled really bad. A few others reported that it didn’t work for them.

2. Best All-Natural: Bonide Go Away! Cat Repellent Granules
If you prefer a different type of solution for deterring outdoor cats, check out these Bonide Go Away! Cat Repellent Granules. All you have to do is sprinkle a four-foot band around the perimeter that you want to protect. You’ll notice immediately that in two weeks, cats are no longer visiting your protected area.

One reviewer had some trouble with both cats and dogs pooping on some rocks she has in her front yard. She did put up a “no pooping” sign but unfortunately, dog owners ignored it (and cats can’t read… not that they’d listen if they could). She was tired of having to clean up after them because it is quite difficult to get poop off rocks. She hated that her front lawn had turned into a public restroom for the strays and pets in the neighborhood. She used these granules hoping that they would deter these activities and she noticed that with one sniff of the granules, the animals that were previously using her space as a public restroom decided to move on to find a better spot to poop. She’s extremely satisfied and relieved and recommends it to anyone looking to repel and deter animals from invading their space.
Some reviewers said that this product didn’t repel targeted animals (dogs and cats).

3. Best Mat: Homarden Cat Repellent Outdoor – Cat Scat Mat
If you prefer a set-it-and-forget-it option to keep outdoor cats away, you may be more drawn to the Homarden Cat Repellent Outdoor – Cat Scat Mat. With each purchase, you get 10 scat mats that measure 16“ x 13“ with one-inch spikes, which altogether cover 13 feet. This is a durable and flexible material that you can use to wrap around anywhere in your yard or house. You can easily cut it to adapt it to any surface. It’s made with high-quality materials and it’s non-toxic for a humane solution to repel cats from your yard. It has a breathable pattern that keeps your plants safe and won’t harm any pets you might have or any cats that attempt to invade your yard.
You can use this mat outdoors and indoors. Simply wrap it around any poles or trees to prevent cats from climbing. It can also protect your garden bed and even your outdoor shed or garage. One reviewer had a problem with neighborhood cats roaming around his property and treating a certain spot next to a window where his dryer vent is installed as their personal litter box. He tried different methods like bleach and ammonia but neither worked. Because they were going close to the dryer vent, he started smelling cat faces in his dryer. That’s when he knew he had to figure out a solution that actually worked.
He still went through and tested a couple of other products, but he loved that this particular product consisted of 10 separate, large individual squares instead of a continuous roll that he would have to cut. He’s very pleased with both the quality of the product and how quickly it was shipped and delivered. The little plastic spikes are quite sturdy and offer a very strong deterrence to animals that treat private areas as their own. After a week of having laid these out, none of the neighborhood cats have been back to do their business by his dryer vent. As you can imagine, he is greatly relieved.
Some users reported that cats “walked right over” the Cat Scat Mat.

5. Best Ultrasonic: AeapYar Ultrasonic Cat Deterrent

This is an ultrasonic cat deterrent that is extremely effective in driving animals away in a humane way. There are five different sensitivity modes that you can set, depending on your needs. The sensitivity modes affect different types of animals, so you can set levels that fit your range area and that signal cats to stay away from the protected area you designate. This ultrasonic cat deterrent is solar-powered and has a charging indicator. You can use AA batteries and you can also charge it with a USB cable.
This ultrasonic speaker is designed to make noise that scares away common outdoor animals. It doesn’t use any chemicals that could be harmful to pets, children, or plants. It’s waterproof so you don’t have to worry about bringing it inside on rainy days and it’s made with a rugged hard plastic construction that also withstands snow, ice, and wind. Mount it to the ground with the provided spike or hang this on objects like trees, fences, or walls. It has a 110° angle and works effectively at distances of about 30 feet.

Choosing the Best: What to Look For
There are different types of outdoor cat repellents. You can go for the classic spray — the one we highlighted as our top choice is non-toxic and safe for use both outdoors and indoors. It’s extremely effective but does require saturation during the first week and repeated applications, especially after rain. There are also granules that require less time on your end — simply set them out and refresh them every two weeks. These are ideal for garden beds and also offer a humane way to deter cats with a combination of strong scents, like essential oils, that naturally deter cats.
Scat mats help you create a physical perimeter and although the spikes may seem harsh at first, cats are intelligent and when they realize that the area has been protected, they will find somewhere else to hang out and do their business. The cat scat mat and the ultra-sonic cat deterrent are the set-it-and-forget-it, low-maintenance options. If you prefer something that offers the most convenience, those two options are your best bets.
Consider year-round care for your backyard, front lawn, and garden beds. You may even choose to use a variety of outdoor cat repellents — the cat scat on a tree or fence, the granules for your garden bed, and a spray for your outdoor shed. Determine the cost of each product, how much of it you’ll need to use, and what that looks like over the course of a year. While a product may be more affordable upfront, you may find that a more expensive purchase up front offers more value over the long term.
Harsh chemicals can not only harm the health of outdoor cats, but they could also be harmful to your health, your kids’ health, and your pets’ health. It’s best to avoid products like these. Instead, focus on non-toxic, humane options that deter cats effectively without posing a health risk to your family and pets, and without harming your lawn, plants, fruits, or vegetables.

Verified Reviews: Users’ Experience
Nature’s Mace Cat Repellent 1 Gallon Spray is a lifesaver for many. This user expresses how this repellent has saved the wild birds he cherishes: “In my area, we have a horrible feral cat problem… I spend lots of cash to feed and attract beautiful birds and the last thing I want to see is some deranged animal munching on a beautiful, feathered specimen. I read the reviews and thought I’d try it. I sprayed it around the far outside perimeter of my feeding station and not one cat crossed the line. I followed the directions to a ‘T’ and I haven’t had any problems with cats. I’ve watched the hairy beasts and they’re not interested in that particular area anymore. I will continue to use it as directed and time will tell. But, thus far, excellent!!!!”
Homarden Cat Repellent Outdoor – Cat Scat Mat is a great option as well. One user got creative and waved goodbye to the persistent outdoor cat that kept approaching: “I cut strips of this to put on the fence outside my windows where the neighbor cat likes to sit and stare at my cat (this annoys her), and also wait for nearby nesting birds to fly into his mouth. He tried to walk on it when I first put it up, but did not go far, and hasn’t been back. Goodbye Otis!”
The Best Outdoor Cat Repellents FAQs (Frequently Asked Questions)
What’s the best outdoor cat repellent?
We highlighted Nature’s Mace cat repellent as the top choice in this list because of how powerful and effective it is. It does require a daily application for the first seven to 10 days but then you can relax a bit, knowing that the outdoor cats have become used to the repellent and won’t be making any plans to return. You can do several follow-up applications but overall, this is a safe repellent that you can use around your children and around your plants and still get year-round protection.
How can I keep my neighbor’s cats out of my yard?
If your neighbor’s cats are popping up as unwelcome guests on your property, your first course of action should be to have a friendly chat with your neighbors. Usually, this can clarify whether they’re actual pets, if they’re strays, or if they’re feral. You can also determine if they may be spayed or neutered to protect your neighborhood from becoming infested with uncared-for kittens. Your other option is to use a nontoxic deterrent like the ones we listed above or place cat mats around your property to keep cats from entering your yard.
How do you stop cats from peeing and pooping in your yard?
The first step for getting cats to stop peeing and pooping in your yard is to completely remove the waste. Yes, it sucks but you do have to pick up the cat poop! Otherwise, they’ll remain attracted to it and keep coming back to the same spot, using it as an open litter box. You can use cat repellent plants in your garden (like rue and lavender) — pair that with a great cat repellent spray, and use any DIY fixes like lime and orange peels. If it’s in the budget, building a fence around your yard can also help to deter cats along with special cat deterrent mats that have prickly protrusions that cats naturally avoid.
Does vinegar deter cats from pooping?
Vinegar doesn’t exactly stop cats from pooping, but it is a repellent for cats. And not just for cats! You can also use vinegar to repel different pests and insects. The strong, sour smell that vinegar emanates is also super effective when it comes to removing the smell of cat poop. When you remove the smell, you also remove the attraction to the same area from that particular cat. So, yes, vinegar is fantastic to use if you’re trying to get a cat to stop coming around and pooping on your property.
