As you probably know, cats follow a particular set of rules that often conflict with human interests. Instead of taking a nap on an outdoor chair or bench, some felines prefer to lay in your herb garden or vegetable garden.

Keeping your cat away from the garden and landscaped areas of your yard can be complicated when you’re dealing with a stubborn animal. Several repellents and deterrents are available online, but which ones are effective and safe for your pet?

We’ve compiled reviews of the nine best outdoor cat repellents to make the decision easier.

The 8 Best Outdoor Cat Repellents

1. Yard Enforcer Motion-Activated Sprinkler – Best Overall

Unlike sprays and granule-based repellents, the Yard Enforcer Motion-Activated Sprinkler does not coat your plants and landscaping with a sticky residue. Most cats dislike being sprayed with water, and this sprinkler system effectively chases felines away with a blast of water and a loud, repetitive clicking sound. The Yard Enforcer is our best overall outdoor cat repellent because of its efficiency, user-friendly design, and multiple features.

Although the sprinkler requires you to leave your water on while in use, the nozzle only functions when it detects motion. The motion-activated sprinkler is powered by four AA batteries that provide over 7,500 activation cycles. Compared to its competitors, the Yard Enforcer offers more features and adjustments.

One of its best features is the day and night detection options. You can select night-only, day-only, or 24-hour mode. Some of the other features include smart sensing technology that learns to differentiate between plants and animals, 3,480 square feet of coverage, a range adjuster that detects felines up to 40 feet away, and two flow-through outlets. After you install the sprinkler, your cat will soon learn to stay away from your garden.

2. Homarden Cat Repellent Outdoor Scat Mat – Best Value

The Homarden Cat Repellent Outdoor Scat Mat is a handy and useful solution to keep cats away from areas where they do not belong. The scat mat has flexible plastic spikes that deter cats without causing them harm. The spikes create an uncomfortable surface that discourages cats from walking, digging, or lying in gardens, flowerbeds, or patios.

The mat’s versatility is what makes it stand out, since you can cut it to fit specific shaped areas, like around plants, tree trunks, or on top of fences to suit your tailored needs.

While it works great in most cases, there have been reports that some cats still find a way around it. Other users also stated that the plastic is not durable and turn brittle in sunlight after a while.

3. Orbit Garden Enforcer Motion Activated Sprinkler – Premium Choice

If you’re looking for a top-of-the-line device to keep the kitties away, try the Orbit 62120 Garden Enforcer Motion-Activated Sprinkler. This Orbit model topped the list of our best premium outdoor cat deterrents.  Rather than the spike design of our previous sprinkler review, the Orbit uses a sturdy metal tripod to stabilize the sprinkler.

The sprinkler has a 120° viewing angle that can detect cats and other creatures from 40 feet away. It has three settings that provide all-day detection, daytime-only monitoring, and nighttime-only monitoring. Unlike other sprinklers, you can change the height to 54 inches and vary the detection angle by adjusting the sensor’s swivel head.

This is handy when your plants are still growing, and you need to change the coverage area periodically. If your grass is dry and you can’t wait for your cat to set off the sensor, you can set a 30-minute watering timer to feed your lawn.

4. Four Paws Keep Off! Cat Repellent Spray – Best for Kittens

Although you can find countless spray deterrents and powders available online and in pet stores, very few products mention they’re safe for kittens. The Four Paws Keep Off! Cat Repellent Spray won our best outdoor cat repellent for kittens prize. Its manageable 16-ounce spray bottle holds the ideal volume of liquid to protect areas from a small cat or kitten.

Using the repellent is straightforward and only requires spraying the target area and waiting for it to dry. You can spray it outside to protect your gardens or lawn furniture and use it indoors on couches, tables, and carpeting. However, the bottle warns that the spray can stain some fabric types, and the manufacturer suggests testing a small section before dousing the entire surface.

Also, it’s probably best not to spray valuable items even if the material isn’t listed on the manufacturer’s warning label. The spray is potent for 24 hours, but you have to reapply it sooner it rains.

5. Solar Ultrasonic Animal Repellent Outdoor

This ultrasonic cat repellent deters animals humanely using high-frequency sound and flashing LED lights, causing no harm to cats. The motion sensor detects movement and activates the deterrent automatically. The solar-powered and weather-resistant device is ideal for outdoor use and is a great alternative to sprays, granules or barriers to repel unwanted feline visitors.

It is easily installed by simply sticking the stake into the ground or attaching it to a wall.

Some cats may get used to the sound over time, affecting its long-term efficiency. Placement should be considered carefully, as it is only solar chargeable, so it might not work as well on overcast days, also if not positioned properly, it can affect the sensor detection.

6. Nature’s Mace Cat Repellent 40oz Spray

With Nature’s Mace Cat Repellent, you can treat up to 1,000 square feet in your yard. It effectively repels felines on shrubs, flower beds, gardens, trees, lawns, and trash cans. The spray contains a blend of natural odors and scents that cats find distasteful, and it’s safe to use around children, vegetables, and other pets.

Unlike similar spray products, Nature’s Mace works all year and does not wash away from watering or rain. Although it’s made from 100% organic ingredients, the scent of the spray is quite powerful. However, you do not notice the foul smell after it dries anymore. In addition to the 40-ounce bottle, the repellent is also available in a 40-ounce concentrate, 1-gallon sprayer, and 1-gallon concentrate.

7. EPIC Scram for Cats Organic Natural Granular Animal Repellent

If you’re turned off by the strong scent from the sprays, you can try the EPIC Scram for Cats Outdoor All-Natural Granular Animal repellent. It has a strong citrus smell that isn’t unpleasant or as noticeable as the potent spray liquids. When you spread the granules around your yard, the scent warns cats that the area is dangerous, and they move away. The product is effective for 30 to 45 days, but it must be reapplied if it rains.

The six-pound bucket of granules can treat up to 1,200 square feet, and you can use gloves or a large scoop to distribute the repellent. Although it’s a nice alternative to powerful sprays, the granular repellent cannot be used on fence posts, trash cans, or most furniture because the wind can blow it on the ground.

It works best near wooded areas, gardens, and vineyards to repel cats. However, it’s not safe to use by children, and you should store it in a secure location away from the young ones.

8. Safer Brand 5926 Critter Ridder Animal Repellent Granules

The Safer Brand 5926 Critter Ridder Animal Repellent Granules keeps animals away by disrupting their sense of taste and smell. It works on multiple animals, including cats, squirrels, groundhogs, chipmunks, dogs, skunks, and raccoons. The granules are a unique blend of piperine, capsaicin, and black pepper. You can use a lawn spreader or the product’s shaker top with a pair of gloves to distribute the material, which lasts up to 30 days.

The granules are effective against domestic and feral cats, but they are unsafe to use around children and should be locked up tight in a cabinet or closet. With its handy shaker lid, it is much easier to apply than other brands, but it seems to have a shorter lifespan than other granules.

Buyer’s Guide: Selecting The Best Outdoor Cat Repellent

We’ve discussed the best cat repellents available this year, but you may still have questions about which products would work best on your property. Before choosing a repellant, consider why you need one on your property.

Are cats disturbing your gardens, or do you have issues with crying felines on your windowsill? The reason for the deterrent can help you determine which product will be most effective.

Types of Outdoor Cat Deterrents

Sprinklers

Of all the repellent types reviewed, the sprinkler was our favorite tool. The premium sprinklers are expensive, but your only cost after the initial purchase is the small amount of water released when it’s triggered. A blast of cold water can convince any cat to run in the opposite direction unless rare, water-loving feral cats visit you.

Compared to other repellents, sprinklers do not produce foul odors or a sticky residue. They’re easy to assemble, and you can adjust the spray pattern and detection angle without studying an instruction manual. As long as a water source is nearby, the sprinkler is the ultimate cat-repellent device.

Mats

We reviewed two mat types, but both products are more effective in preventing nesting behaviors than keeping a cat from climbing a ledge or windowsill. The harmless spikes are uncomfortable if the creature lays down, but some cats and other animals can walk over the mats without discomfort.

Sprays

Sprays are effective deterrents and can be used on multiple surfaces, but you have to reapply the spray after it loses potency. Some sprays are smellier than others, but the products we reviewed claim to be safe for plants, animals, and children.

Granules

Granules work best in gardens and landscaped areas, and their odor is less offensive than the sprays. Since the wind can easily blow them away, they’re not practical for furniture or vertical surfaces.

The most significant disadvantage of the granules is the danger they pose to young children. Granule-based repellents were the only products we reviewed with ominous warnings about exposing the substance to kids.

Ultrasonic Devices

You can find several ultrasonic repellants available online that range in price from $30 to $200, but we’re not convinced that the high-end models are more effective than the cheaper ones. Most ultrasonic units include noise and light deterrent to chase off cats, but it’s unclear whether the audible noise, ultrasonic noise, or strobing lights irritate felines the most.

If it keeps cats away, the reason may be unimportant, but until high-pitched sounds are proven to repel cats in a non-laboratory environment, we suggest buying one of the less expensive products we reviewed rather than an expensive one.

Another Option to Consider

In addition to the countless products available to deter felines, you can erect physical barriers around your property to keep the cats away. Fencing doesn’t work for every situation, but it’s effective in areas like vegetable gardens if the walls are high enough to keep cats out.

You’ve probably seen recipes for natural repellents online, but it’s best to avoid them unless you’ve consulted a veterinarian. Cayenne pepper concoctions and other potent natural repellents may repel cats, but until they’re proven harmless, it’s safer to use the repellents we discussed.

Summary

After examining our reviews, we hope you have an idea about which repellent will work on your property. Our top pick was the Yard Enforcer Motion-Activated sprinkler. It impressed us with its customizable features and simple design, and it seemed more effective than other products.

The Homarden Cat Repellent Outdoor Scat Mat won the best value award, and we liked how easy it is to cut and position in smaller areas like potted plants. Cats are inventive and persistent when navigating your yard, but their journeys are limited when you use one of our recommended repellents.
