Cat repellent can be used to keep a cat away from potential danger, like a toxic houseplant, or from sinking their claws into your valuables, like a brand new sofa. The term cat repellent can refer to a variety of products including sprays, adhesive tapes and panels, and even mats that deliver a mild static shock upon contact.
If you find yourself in need of cat repellent, cat behaviorist Mieshelle Nagelschneider of The Cat Behavior Clinic strongly advises selecting a product in accordance with the pet training principal of "LIMA," an acronym meaning "Least Invasive and Minimally Aversive."
"Cats don’t need much of a negative outcome to deter them from jumping up on the kitchen counters or clawing furniture. In fact, even a minor inconvenience will usually be quite effective, and most cats will learn after three experiences with a cat deterrent," Nagelschneider told The Spruce Pets.
We purchased 18 cat repellents to see how well they could keep curious cats at bay in real homes. For two weeks, we observed the effectiveness of each product, paying close attention to our participating cats' reactions and behavior adjustments. We also took note of our own feelings towards the cat repellent and any lingering residue left behind or obnoxious smells emitted.
Best Spray
NaturVet Bitter Yuck! No Chew Spray
Can use indoors and outdoors
Vet formulated
Works on topical medications
Comes with satisfaction guarantee
Doesn’t stain
Effectiveness varies
Strong smell
This no-biting spray focuses on deterring your cat from chewing on furniture and wounds by leaving a bitter-tasting residue on the target area. The rosemary-based formula was developed with vets and can be sprayed on top of topical medications and bandages as an added protection for healing stitches or sores. It also works on furniture, won’t stain fabrics, and can be used safely around plants. This will need to be continually reapplied as it fades or gets washed off, and it may take several applications to drive the message home with your cat. As with most natural products, effectiveness will vary. We like that it can be used indoors and outdoors, but beware of spraying in small spaces, as the rosemary scent can be strong even after drying.
Type: Spray | Size: 8, 16, and 32 ounces | Active repellent: Rosemary
Best Tape
Sofisti-Cat Scratch Deterrent Tape
No chemicals
Effective on multiple surfaces, including furniture, doorways, and drapes
Can be cut to size
Very visible on surfaces
Sofisti Cat Scratch Deterrent Tape is a double-sided tape that is safe to apply throughout surfaces in a home including drapes, upholstery, and walls. It can be purchased as a 15-foot roll of tape or as a pack of 15 x 12-inch sheets.
We used the roll to deter a cat from scratching at a wooden door and doorframe. The tape is effective, easy to cut, and affordable, so there is no need to ration its use. The deterrent tape looks white on the roll, but appears more translucent once both sides are exposed—one stuck to the surface you want to protect and the other ready to repel claws. While not opaque, the tape is still very noticeable on surfaces.
The tape is intended to help you train your cat to direct their clawing elsewhere, such as a scratching post placed nearby. You can encourage your cat's better behaviors by giving them treats when they use the proper surfaces, instead of your furniture.
Type: Tape | Size: 15 feet x 2.5 inches; 15 feet x 12 inches | Active Repellent: Sticky film
Best Aerosol
Sentry Stop That! Behavior Correction Spray For Cats
Immediate results
Scientifically proven
Compact size stores easily
Noise may upset anxious cats
Runs out quickly
This two-fold spray may come in a small container but packs a disciplining punch. The Sentry Stop That! Behavior Correction Spray is an effective training tool that often only needs to be dispensed once to stop unwanted behavior—but it needs to be done immediately following the “wrong” behavior so your cat will associate the deterrent with its actions. When the product is dispersed, it releases a strong bad-smelling pheromone in unison with an abrasive noise (for cats). Subsequent offenses can often be curbed by simply responding to your cat’s behavior by picking the canister back up since they will remember the effect, so you don’t even have to use the actual product every time. We like the small travel size of the bottle since it can easily fit inside a bedside table or kitchen drawer for easy access, but that limits the number of sprays available. Keep in mind that it’s possible that the abrupt noise may upset overly anxious cats exhibiting anxiety-rooted behavior.
Type: Spray | Size: 1 ounce | Active repellent: Loud noise and pheromones
Best for Outdoors
Safer Brand Critter Ridder Animal Repellent
Quickly covers large outdoor areas
Effective for up to three days in Spruce tests
Works on several species
Dries odorless (for humans)
Strong chemical scent before drying
The Safer Brand Critter Ridder Animal Repellent is formulated specifically for outdoor use, and will deter cats as well as other animals like skunks and dogs, raccoons, and squirrels. One bottle is enough to cover 320 square feet. The manufacturer claims a 30-day effective period, but during real-world tests of our own, we found it only effectively repelled critters for up to three days. During our testing period, we applied the spray to an outdoor stoop and front door entryway, two popular escape routes for our cat. The cat immediately froze upon approaching the sprayed areas and distanced themselves from the treated area. Although this spray dries odorless, we noticed the spray initially has a strong chemical smell. This spray works by combining a combination of bad-smelling and terrible-tasting ingredients, ranging from rotten eggs and dried blood to black pepper. It also contains capsaicin, a chili pepper derivative, so be sure not to inhale anything during application. It’s also available in granule form.
Type: Spray | Size: 32 ounces | Active repellent: Dried blood, putrescent egg, garlic, black pepper oil, capsaicin
Best for Furniture
Stelucca Amazing Shields Cat Scratch Deterrent
Easy to apply and can be cut to desired dimensions
Effectively keeps cats from clawing fabric surfaces
No smells or liquids
Not appropriate for leather or faux leather
Wears out quickly in high traffic areas of a home
The Stelucca Amazing Shields Cat Scratch Deterrent is a highly effective, chemical-free cat deterrent designed to protect upholstered furniture pieces from becoming your cat's manicurists.
Each transparent sheet has a sticky side that can be applied to a variety of fabrics but is not recommended for use on real or faux leather. We found it easy to adhere and it successfully protected the side of an armchair from the fury of our cat's claws. These shields felt more substantial than others that we tested, but they are still flexible and can easily be cut to size with a standard pair of scissors. After a few days in high-traffic areas, we did notice some gaps where the adhesive was starting to wear, but the protection was still intact.
From playtime to survival, a cat's claws are their essential multipurpose tools and they instinctually seek out surfaces to claw to keep their nails filed and healthy. It's important to have designated areas, like a scratching post, and interactive toys, so your cat can safely unfurl their claws when the mood strikes.
Type: Adhesive shield | Size: 17 x 12 inches | Active Repellent: Translucent panel
Best Scat Mat for Guarding Plants
D&D Cat Deterrent Scat Mat
Suitable for areas and objects that are harmful to cats but cannot be sprayed, like plants or food preparation surfaces
Effective in keeping cat away from plants during our real world testing
No chemicals involved
Can be cut to size
Won't stop cats from attacking leaves and branches
Some plants are not safe for cats to play with, and while cats are drawn to plants and like to dig in their dirt, they need to be taught to stay away. A scat mat is an effective way to keep your cat from disturbing the plants inside and outside your home.
The D&D Living Cat Deterrent Scat Mat has plastic spikes that will not cause any injury to your cat's paws but will cause a bit of a surprise if they step on them. It will deter cats from jumping up or going near an area that you want them to stay away from. The mats can easily be cut to the size you need and the strips can be connected to each other. The cat repellent also comes with six large staples that let you anchor the scat mats right in the dirt of your plant. While these mats won't prevent your cat from attacking leaves and branches, we found that they will successfully keep cats from digging in planters, as was the case in our real world testing.
This scat mat from D&D is made of polypropylene and comes in a set of 10. Each mat measures 16.5 x 13.4 inches and has 1-inch plastic spikes. These mats will cover up to 15 square feet. Unlike sprays, their effectiveness is consistent and there is no detectable scent.
Type: Scat mat | Size: 16.5 x 13.4 inches | Active Repellent: 1-inch plastic spikes
Best for Kittens
Bodhi Dog 3-in-1 Cat & Kitten Training Aid
Non-toxic and chemical-free
Family-owned
Available in multiple sizes
Eco-friendly production and packaging
Contains lemongrass oil
May stain fabrics
For pet owners looking for a natural deterrent or a safe product with kittens, the Bodhi Dog 3-in-1 Cat and Kitten Training Aid spray is your best bet. This cat repellent uses essential oils and botanical essences, like rosemary, cinnamon, and lemongrass, to create an unpleasant smell your cat will likely want to avoid. It’s safe to use directly on plants and most surfaces, though it may stain fabrics, so it’s best to do a test patch before applying. This formula also contains bitters to deter cats from chewing sprayed surfaces as well. The rub is that, as with some natural products, it’s not as effective as products with synthetic or chemical deterrents. It also contains lemongrass oil, which can be toxic to cats, though that’s usually when it is ingested directly or diffused. If it works, you’ll have to reapply as the smell wanes, and it helps if you like the smell of lemongrass and rosemary yourself.
Type: Spray | Size: 8 and 32 ounces; 1 gallon | Active repellent: Natural botanicals, essential oils, and bitters
Best DIY
Reynolds Wrap Aluminum Foil, 200 Square Feet
Quick fix
Multiple uses
Inexpensive
Completely covers surface
Looks obvious and ugly
There’s something about the combination of texture, sound, and shiny surface area that absolutely grates on cats, and they will actively avoid it, at least for a little bit. Cats have sensitive hearing, and the crinkle of foil is incredibly dissonant for them. Additionally, the reflective surface may trick cats into thinking that the foil is a shallow pool of water. Cats jumping on the kitchen counter? Slap down some aluminum foil and they likely will learn their lesson within their next few jumps. You can also lay foil down in front of areas you want the cat to stop getting into. However, this convenient and inexpensive solution isn’t a fail-safe deterrent as some cats will only be temporarily off-put by aluminum foil and no longer avoid it once they know it’s not a threat. It’s also not a good long-term solution since it sticks out like a sore thumb and requires you to cover a surface, leaving it unusable.
Type: Cover | Size: Custom | Active repellent: Aluminum foil
Final Verdict
While testing cat repellents we found that different cats responded to different deterrents. But we think that you’ll have the best chance of keeping your cat away from plants or other off-limits areas with NaturVet Bitter Yuck! spray.
What to Look for in Cat Repellent
“Being the sensitive creatures that cats are, a mild deterrent is not only usually enough, but doesn’t need to be used for very long due to their shallow learning curve,” Nagelschneider told The Spruce Pets. “A cat repellent should also be remote, so the cat owners are not involved. We don’t want the cat to endure the stress of their cat owner deterring them. Yelling at your cat or squirting them with a squirt gun can break the cat/human animal bond and increase stress, lead to aggression issues, create owner absent behavior (i.e. clawing your favorite chair when you’re not around) and even create new stress-related behaviors (like chewing on the wicker basket).”
Behavior
First clearly identify the behaviors you’re trying to deter. Some products focus on just one or two of the undesired behaviors while others address them all. Decide whether you’re trying to prevent lounging, scratching, chewing or spraying, then ensure the product specifically addresses that behavior.
Sticky tape or protective plastic barriers can prevent lounging and scratching but won’t help with spraying. Sprays and pellets can contain ingredients that have a foul smell to keep animals away from a particular area and/or contain bittering agents that will prevent chewing. If the product label does not mention the specific behavior you’re trying to prevent, keep looking for one that does.
Location
The first determination is whether you need an indoor or outdoor product—or one that can be used in both locations. Some products can only be used indoors because they do not hold up to the weather or rely on concentrated odor as a deterrent. Others may need to be plugged into an electric outlet or can only be used outdoors because the smell is unpleasant to humans, or the ingredients are not appropriate for application to furniture and fabrics.
Read the label thoroughly before you purchase to make sure it is appropriate for the surfaces you want to protect. Whenever using a new product on objects such as furniture, painted surfaces, curtains, rugs, or decking, always spot test a small and unnoticeable area for staining and odor acceptability. If the area is negatively affected by the spray, you can apply it onto a piece of cloth or towel, let dry and then place it onto the area you want protected.
Coverage Area and Application Rate
Consider how much space you’re trying to protect and whether you’ll need to treat the area just once, daily or weekly. Are you trying to keep feral cats from using your flowerbed as a litter box or just trying to keep your tenacious kitty off your grandmother’s antique chair? Some cat repellents are designed to cover small areas—a few feet, at most—while others can cover up to 3,000 square feet or more. Some can be applied just once (thoroughly) while others require multiple, consistent applications to truly break the habit.
Many sprays and pellets are sold in a variety of volumes and sizes so check the label to ensure you’re getting enough product to ensure you can follow application recommendations for the best chance at success.
For large outdoor areas, consider motion or infrared activated repellents that use sound, water, flashing lights or a combination of all three. However, cats are cunning and can often figure out through trial and error where the edge of coverage is. Then they just modify their path to avoid triggering sensors. To avoid this phenomenon, you might need to reposition or move the sensor regularly to keep the cat guessing.

Do cat repellents really work?
“Yes, the ones that work do,” says Nagelschneider. “You also need to use the right deterrent for the job. Bitter apple spray may work well to keep a cat from chewing on electrical cords but spraying a product like this or other scent deterrent products along the perimeter of your lawn will not keep an outside a cat away. They will walk right over them.”
-
Do sonic/ultrasonic cat repellents work?
“We have been recommending these for many years to deter outside cats from entering your property,” says Nagelschneider. “However, these should never be used inside the home and they will need to be turned off if/when your inside cat goes outside.”
