Cat repellents can help cat owners keep their kitties away from spaces in the home where they’re not permitted and ensure they don’t damage furniture or plants. If you’re currently dealing with feral or neighborhood cats entering your property, an outdoor cat repellent can discourage them from entering your yard. Cat repellents are available in a variety of forms including indoor and outdoor sprays, repellent mats, furniture pads, motion-activated devices, and ultrasonic options.

If you’re ready to find the best cat repellent to match your specific needs, continue reading. We researched and tested some of the top products on the market and narrowed down our selections to the repellents featured below.

Verified Review: Our Hands On Experience

Reading a product’s listing can tell you something about how it should work, but actually testing the product and seeing the results is something entirely different. Before writing this review, we purchased and tested several cat repellents to see how they would work at keeping our cats out of specific rooms in our home, off furniture pieces, and away from outdoor spaces. The top-performing products are featured below, but here are a few additional observations we made for each product:

  • PetSafe SSSCAT Motion Activated Spray Cat Deterrent: Our cats definitely don’t like the sound this spray deterrent makes and it has helped to keep them away from furniture and other areas we don’t want them in. However, the spray can seemed to get empty quickly, which can make this an expensive option with all the replacements you’ll need to order.
  • Homarden Cat Scat Mat: We liked that we could customize the size of these mats by cutting them down to fit our exact needs. We also found that our cats really didn’t like the texture and stayed away from the areas we used them. However, we found that using them on flat and smooth surfaces, such as counters or hardwood floors, wasn’t ideal because the mats will slide around too much.
  • Lubatis Ultrasonic Animal Repeller: One of our friends was complaining about feral cats entering her property, so we tried this ultrasonic repeller in her yard. Overall, it was quite effective at keeping cats away from areas close to the device, but not always as effective for other areas of the yard.

The Top Picks for the Best Cat Repellent: Ranked

PetSafe SSSCAT Spray Pet Deterrent, Motion Activated Pet Proofing Repellent for Cats and Dogs, Environmentally Friendly
  • PROTECT FURNITURE: Place SSSCAT Spray Deterrent on countertops, next to the trash can or near rooms to keep curious pets out of certain areas of your home
  • MOTION-ACTIVATED: When your pet is within 3 feet of the spray deterrent, the motion-activated sensor releases a quick burst of spray
  • SAFE FOR PETS: This odorless and harmless spray is safe to use around your pets and does not leave any stains or residue on your furniture
  • REPLACEMENT CAN AVAILABLE: Each can of spray deterrent holds approximately 80-100 sprays; when your current can is out of spray, simply purchase a SSSCAT Replacement Can
  • BATTERY OPERATED: Motion sensor requires 4 AAA batteries to operate (batteries not included)

The SSSCAT Motion Activated Spray System from PetSafe is our overall top pick. The reason we selected this as our favorite cat repellent is that we found it to be quite effective at keeping cats away from furniture or out of areas in the home where we didn’t want them to enter. The spray is motion-activated, so you simply need to place it at the entryway of the area you want cats to stay away from, and when they get within 3 feet of it, the sensor will release a spray.

The spraying sound will startle cats and help them learn that they shouldn’t enter that area in the home. No odor is released, so you don’t need to worry about the spray making your house smell. It is also completely safe for pets and doesn’t leave a residue on furniture or carpets.

The motion sensor is powered by four AAA batteries. This makes it easy to replace the batteries when needed, and you won’t need to seek out any special types of batteries. The included can of spray provides between 80 and 100 sprays. Replacement cans are available through PetSafe when needed.

Best Cat Repellent: Reviewed for 2021 FAQs (Frequently Asked Questions) 

What is the most effective cat repellent?

The most effective cat repellent will vary based on your need. For example, some cat repellents are designed for indoor use, while others are more suited for outdoor use. The right repellent can also vary depending on whether you are trying to keep cats away from an entire space, or just a specific item like a piece of furniture or a plant.

The PetSafe SSSCAT Motion Activated Spray Cat Deterrent was our favorite cat repellent, but we also liked the Homarden Cat Scat Mat and Lubatis Ultrasonic Animal Repeller.

What is the best cat repellent for outside?

We think the Homarden Cat Scat Mat is the best cat repellent for the outside. This spiky mat can be placed around areas that you don’t want a cat to access to keep them away. If you’re looking for an outdoor repellent to keep cats off of your entire property, we’d suggest investing in an ultrasonic device like the Lubatis Ultrasonic Animal Repeller.

What is the best feral cat repellent?

If feral cats have been entering your property and you wish to keep them away, we’d suggest trying the Lubatis Ultrasonic Animal Repeller. You can also try the Homarden Cat Scat Mat if there are just a few areas of your property you want to keep them away from.

Are cat repellents harmful to humans?

Most cat repellents are designed to be safe for humans as well as cats. Sprays to keep cats away are not poisonous, they are simply formulated to smell very unappealing to cats to make a particular area or piece of furniture less appealing. You can also consider making your own natural, homemade spray as well.

How do you make a homemade cat repellent?

There are many natural ingredients and textures that cats do not like the smell of. You can try some of these to make your own homemade cat repellent. These natural ingredients and other DIY solutions include:

Apple cider vinegar
Citrus fruits and citrus-scented sprays
Cayenne pepper, dry mustard, cinnamon, garlic, and lemon essential oil mixed together
Double-sided tape
Flipping carpet runners or area rugs upside down
