The 10 Best Outdoor Cat Repellents

While you may enjoy cats, you probably don't appreciate uninvited neighbor and stray cats straying into your yard.

Outdoor cat repellents, which come in a variety of varieties, can help chase away outdoor cats quickly and gently. The question is, which type should you buy?

When looking for a repellent, consider how it repels, the amount of the area you want to cover, the brand, and the price.

It might be difficult to navigate through the many options and reviews available online, so BestForPets (bestforpets.org) simplified your search for the best outdoor cat repellents by selecting our ten favorites below!


Best Overall: Homarden Cat Repellent Outdoor Scat Cat Mat

In our opinion, Homarden’s scat cat mat is the best overall cat repellant. It is non-toxic to both cats and garden plants, and it is heat resistant.

Choosing The Best Cat Repellent Buyer's Guide

Cats are excellent pets, but if your neighbor’s or stray cats keep roaming into your yard and wreaking havoc, you’ll want to find a strategy to discourage their behavior.

Why Do You Need a Cat Repellent?

Outdoor cats that enter your yard can cause property damage by digging and may even be hostile towards your own pets.

They can also use your yard as a toilet, leaving nasty surprises behind that may include parasites that are harmful to other animals or even you.

Stray cats may also be infected with diseases like mange, which can easily transmit to other cats. Cats that roam into your yard, as natural predators, can attack local wildlife such as birds or squirrels that you may be fond of.

Obviously, you want to keep these annoyances at bay. Cat repellents make it simple to keep outdoor cats out of your yard. They are usually simple to apply and will not harm cats, merely deter them.

What Types of Cat Repellents Are There?

Depending on your demands, there are a few different cat repellents available.

Sprays for Cats

Outdoor cat repellent sprays are similar to those used to keep cats from leaping on counters or scratching furniture indoors.

They are typically non-toxic and will not hurt your garden or your household. They usually function by emitting an odor that cats find undesirable. Simply spray in areas where you don’t want outdoor cats.

Water Repellants

Most cats dislike water, which is why sprinkler-style deterrents can be so effective. These cat repellents are motion actuated and will spray a stream of water if movement is detected.

Cats are not hurt, only irritated. This is perhaps the simplest method for keeping outside cats at bay.


These employ sound to deter cats from entering your yard. Furthermore, because they are motion-activated, they emit a sound that is unpleasant to cats but is typically undetectable by the human ear.

They can be solar-powered or battery-powered, and they can even have flashing lights or an alarm.

What To Look For When Buying A Cat Repellent

When it comes to selecting the best outdoor cat repellant for you, consider the following factors.

Placement, Placement, Placement

Check repellents to see if they should be used indoors or outdoors. Some are designed to keep indoor cats away from goods, while others are designed to keep outdoor cats away.

Some can be utilized both inside and outside.


Different repellents will be effective in different sized areas. Some may only work up to a few feet in height, but others may operate up to thousands of square feet.

Consider the area you want to protect and double-check the coverage details.


If you opt to go with something motion-activated, you should look into the product’s durability. Is it waterproof or useable in all weather conditions? Will animals easily knock it over?


You don’t want to injure outside cats, but you also don’t want them to stay away. Make certain that the things under consideration are safe for cats (and any other animals, including your own).


It is critical to understand a product’s brand. Is the product’s brand notorious for being shady? Is there a guarantee or warranty? Are they old hat, or are they new to the outdoor cat repellent market?


Some products will be far more expensive than others, but they may also perform significantly better.

Before purchasing, consider how much you’re willing to pay to get rid of unwanted animals and how much value you’re getting for your money.

Customer Feedback

One of the finest methods to investigate a product is to read what others have said about it. Examine both the positive and negative evaluations, but be wary of fraudulent reviews.


While there are the best outdoor cat repellents available, a handful stand out above the rest.

BestForPets (bestforpets.org) believes Homarden Cat Repellent Outdoor – Scat Cat Mat is the greatest overall because of the positive feedback.

The Ultrasonic Animal Deterrent with Motion Sensor and Flashing Lights is unquestionably the finest value, especially if you want a motion-activated repellent.

Finally, with its utilization of motion, water, and sound, the Yard Enforcer Motion-Activated Sprinkler is a premium option.
