The 11 Best Cat Repellents, Sprays & Deterrents

You adore your cat, but that doesn't mean they don't irritate you from time to time.

Cats are infamous for getting into or harming things they shouldn't, so it's fair if you want to keep your pet from chewing up your vegetable garden or clawing up your couch.

One of the simplest and most efficient ways to deter undesired feline behavior is to use a repellent spray.

These sprays can be applied directly to the area you want to protect, and they use strong aromas or flavors to keep your cat away from whatever you want them to leave alone.

BestForPets (bestforpets.org) takes a closer look at our best cat repellents, sprays & deterrents on the market today in the reviews below.

Each of the options below is safe and effective, so you won't damage your cat while keeping it from destroying your belongings.


Best Overall: Four Paws Healthy Promise Cat Repellent Spray

Four Paws Healthy Promise Bitter Lime Anti Chew Spray for Dogs

View on Amazon

Four Paws Healthy Promise  uses the bitterness of limes to keep your cat at away. Most cats are deterred by the natural taste and odor, and it also works on dogs, so you can defend your home from your entire zoo.

Because the spray contains natural substances rather than harsh chemicals, it is totally safe for cats to swallow (though ideally they will not). It is also suitable for use on a wide range of materials, including wood and textiles.

It’s even okay to spray on your cat, for example, if you’re attempting to convince them to stop licking a sore region.

But be warned: this stuff is potent. If you spray it in an enclosed space, it can rapidly become overpowering. If nothing else has worked, it may be your best option.

Four Paws Healthy Promise is an extremely effective repellent and an obvious pick for the finest cat repellent spray.


  • Utilizes the inherent power of bitter limes
  • It is also effective on dogs.
  • Most surfaces are safe to use.
  • It is safe to spray straight on cats.
  • There are no harsh chemicals.


  • Can be overwhelming

Best Buy: PetAg Boundary Indoor/Outdoor Cat Repellent Spray

Lambert Kay Boundary Indoor/Outdoor Cat Repellent Pump Spray

View on Amazon

If you want to keep your cat away from numerous surfaces, PetAg Boundary can be used both inside and outside. It’s perfect for keeping cats away from gardens, garbage cans, and furniture.

Despite its versatility, the spray is reasonably priced. It comes in a large, 22-ounce bottle that is yet less expensive than many other, smaller sprays.

As a result, it’s our recommendation for the best cat repellent spray for the money as well as the best cat repellent spray for furniture.

The spray’s effects persist for 24 hours, so while it won’t give permanent deterrent, it should be sufficient to prevent temporary misbehavior. You can quickly teach your cat certain areas are off-limits if you are careful about reapplication.

However, because it has a strong odor, you should avoid using it indoors. It smells like burnt plastic, which you probably don’t want filling your house.

PetAg Boundary is one of the most cost-efficient solutions on the market for a cheap, effective solution.


  • Excellent value for money
  • Can be utilized both inside and outside.
  • The effects last 24 hours.
  • It comes in a big 22-oz. bottle.


  • Not a long-term deterrent
  • Has a foul odor

PetSafe SSSCAT Spray Pet Repellent – Excellent Option

PetSafe SSSCAT Spray Replacement Can

View on Amazon

The most difficult aspect of applying a deterrent is catching your cat in the act. PetSafe SSSCAT addresses this issue by serving as a remote guard dog on your behalf.

It must be used in conjunction with the SSSCAT Spray System, which is a motion-activated gadget that sprays an odorless stream at your cat when they enter areas they should not be in. As a result, it is both incredibly effective and absolutely safe.

Of course, if you don’t have that system, you’re stuck with a spray can (which can still be effective). Given the price, each can only provides enough spray for roughly 80-100 sprays.

It has a range of up to 3 feet, allowing you to defend several regions with a single device. It also works on almost any animal, not just cats.

If you’re serious about keeping your cat away from particular locations (and prepared to spend money on it), the PetSafe SSSCAT and SSSCAT Spray System are a very effective, high-tech solution.

To summarize, this is our top recommendation for the finest cat deterrent spray this year.


  • Uses a motion-activated mechanism.
  • Spray has no odor.
  • Protects from up to 3 feet away.
  • Can defend many places at the same time


  • To be effective, a separately purchased system is required.
  • There isn’t much spray for the price.

Outdoor Cat Repellent Spray by Colton’s Naturals

Cat Repellent Outdoor Spray Indoor 32 OZ 100% Organic & Natural

View on Amazon

Colton's Naturals  is only intended for outdoor usage due to the strong odor of peppermint and citronella oil. That restricts its usefulness, but if you only want to keep the neighborhood cats under control, it’s an excellent pick.

The spray is long-lasting, with each application lasting 2-4 weeks. You may need to reapply it after rain, but it should provide adequate protection in the meanwhile. Of course, this also means you’ll have to cope with the stink throughout that time.

Because the components are 100% organic and suitable for animals and children, you can spray it liberally throughout your home.

Because this stuff is pricey, it’s a good thing it works. Having said that, the bottle is prone to spilling.

If you have a feral cat problem, Colton’s Naturals is a wonderful approach to keep things under control, if a little pricey.


  • Controls feral cats well.
  • Long-term effects
  • The ingredients are both safe and organic.
  • Extremely efficient


  • Cannot be used inside.
  • On the expensive side
  • The bottle is prone to leakage.

Critter Ridder Animal Repellent, Safer Brand 5935

Safer Brand 5935 Critter Ridder Animal Repellent Ready-to-Use Spray

View on Amazon

The Safer Brand Critter Ridder has the nicest name on this list, but the formula isn’t nearly up to the same standards as our top options.

In addition to cats, it claims to repel a number of pests such as squirrels, skunks, groundhogs, and raccoons. This stuff works, but not on every animal and not all of the time.

It only lasts around 48 hours (less if it rains), and cats can develop acclimated to it rapidly if you don’t reapply it liberally.

It’s not overbearing to human noses; in fact, you might not even be able to smell it. It appears to rely on taste rather than odor, as the mixture contains chemicals such as black pepper and capsaicin.

As a result, Safer Brand Critter Ridder is best suited for things that cats eat rather than those that they scratch up or roll in. That makes it ideal for vegetable gardens, but it won’t do much for a couch where they sharpen their claws.


  • Excellent for preventing destructive chewing
  • To humans, it has no odor.
  • To some extent, it works against a range of pests.


  • It washes away in the rain.
  • It only lasts around 48 hours.
  • It is possible for cats to become acclimated to it.

Choosing the Best Cat Deterrent: A Buyer's Guide

Most cat owners have no experience purchasing a repellant, so it’s understandable if you have a slew of questions.

We’ll lead you through frequent questions in the tutorial below so you know what to look for in a cat repellent.

What Is the Mechanism of Cat Repellents?

There are numerous possibilities, each of which works in a unique way.

The most frequent ones employ unpleasant odors to deter your cat. Cats have significantly stronger senses of smell than humans, therefore a foul stench can be excruciating for them.

The disadvantage is that many of these repellents may repel you as well, so you may not want to spray them inside. Others utilize unpleasant tastes to dissuade cats.

These are employed when it is desired to inhibit biting rather than scratching. This reduces their overall utility, and you risk your cat developing a taste for the deterrent.

Others employ compressed air or water jets to make cats flee. These can be successful, but they are also costly and prone to failure.

Furthermore, if your cat realizes that the machine isn’t a threat, they may simply ignore it.

Finally, the greatest cat deterrent for you will be determined by the behavior you want to discourage and the things your cat is most likely to be repulsed by.

Is it safe to use cat repellents on my cat?

Yes, the most are. They employ compassionate approaches to gradually change your cat’s behavior.

The great majority contain natural compounds that cats despise, such as citrus or cinnamon. Although these are not toxic to cats, they will go out of their way to avoid them.

Exposure to unpleasant tastes or odors will not hurt your cat, despite the expressions they will produce. However, unless the recommendations state otherwise, you should avoid applying any of these products directly to your pet.

Some repellents, such as those that blast your cat with compressed air, can make some cats anxious. As your cat becomes more nervous all the time, this might lead to more misbehavior, such as aggression.

However, this type of reaction is uncommon, and most cats will simply learn to leave the protected area alone.

Is it safe to use these products around my family?

If they’re safe for your cat, they’re probably safe for the rest of your family. However, this does not guarantee that your family will enjoy them.

Many of the scent-based solutions are really potent; they must be to keep your cat at bay. However, you will have to put up with a bad stench as well, so these may not be suitable for indoor use.

If you must use something inside the house, it must be something that everyone in your family (except, of course, the cat) can accept. Otherwise, you’ll be miserable in the process.

Do I Need to Continue Using These Products to See Results?

Each product has a unique lifespan. Some are only effective for a few hours, while others can keep cats away for weeks.

The ultimate goal is to wean yourself off the repellent completely. The goal is to repeatedly discourage your cat from visiting a specific place or engaging with a specific object until they simply stop trying.

You can cease applying a deterrent once your cat has learned to avoid the area on their own. However, until then, it is critical to use them religiously or risk ruining all of your gains.


Four Paws Healthy Promise  is one of the most adaptable solutions we’ve seen, which is why it received our highest rating.

It will not only protect every surface in your home, but you can also put it on your cat, making it an excellent solution for preventing unwanted licking or biting.

PetAg Boundary  is an excellent choice for both indoor and outdoor use, with the added benefit of being extremely economical.

It’s worth a closer look if you’re attempting to keep every cat in the neighborhood at bay.

It is difficult to keep your cat away from specific areas, but with the help of the deterrents on our list, you should be able to get some peace of mind.
