The Best Cat Repellents (Review) in 2021

Last Updated July 9, 2021

Cats may have a reputation for being fastidious with their own cleanliness but when it comes to your garden, yard or even your home, they can cause quite a mess. Unwanted cats can choose to use your garden as their personal toilet stop or a place to leave a mating calling card. And they are not averse to digging up a border or two. Even if you have your own cat, their bad habits can spill over into your home, from clawing furniture to clambering across your kitchen worktop. If this sounds like just some of the feline problems you are encountering, then it’s worth considering a cat repellent.

Cat repellents are intended as a harmless deterrent to keep cats at bay. From sprays and motion sensors to ultrasonic devices, the aim of a cat deterrent is to safely move a feline away and stop any anti-social behavior. But which deterrent do you pick and how do you know it will work? We take the stress out of choosing with our round up of what we think are some of the best cat repellents you can buy.

The Best Cat Repellent

If you have a cat that doesn’t respect boundaries or scratches up your furniture, then this smart indoor spray pet deterrent from PetSafe can help you regain control. Using an odorless spray, you set the SSCAT near to wherever your cat is playing up and the motion sensor will trip when they come within three feet. This harmless spray deterrent – which also senses your pet’s body heat – is intended to move them away so that your cat quickly learns the no-go zones. Ideal for use on kitchen counter tops, by furniture or trash cans, the SSCAT can also be used on the inside of doors into rooms you want to be a no-cat zone. Each canister gives around 100 sprays and there’s nothing in the spray to harm your pet, furniture or surfaces. The SSCAT motion sensor runs on four AAA batteries, which are not included in the initial pack. But for less than $30, SSCAT tops our best cat repellents list.

Best Cat Repellent Buying Guide & FAQ

Why You Need a Cat Repellent

As much as we may love cats, they do have some behaviors that can be less than desirable, particularly when it comes to your backyard. Digging holes, using the flowerbed as their toilet, chasing birds, marking their territory…these are natural actions of felines, but they can leave your outdoor space a little worse for wear. You may also be allergic to cats or are concerned about the health implications of picking up something unpleasant from cat parasites or even a cat’s feces. And, especially if the kit it not yours, then you want a deterrent to keep those feral cats away. An outdoor cat repellent is a safe way to keep the neighborhood cats at bay. You can also use an indoor cat repellent to help protect your furniture or carpet from the claws of your own pet cat and even to help with your kitten training for a happy, calm home.

What to Look for in a Cat Deterrent

Location – before buying a cat repellent, consider where it is you need it and whether you need an indoor or outdoor product. Also, consider whether it needs to be plugged into a power source or whether it is battery or solar power operated so that you pick the most suitable product for the intended location.

  • The cat’s behavior: Are you wanting to generally shoo a cat or gang of feral cats away from your property or is there a specific feline behavior – such as scratching furniture or digging up plants – you want to discourage. Knowing what it is you want the repellent to do, means you can get a device that is both effective and suited to a specific cat-repelling job.
  • Durability: Repellents for outdoor use need to be tough and made from durable materials as well as being weatherproof and can function if wet. The power source, especially if it’s battery-operated, needs to have a decent usage life and should be rechargeable if at all possible.
  • Coverage required: As well as the location, you need to know how far you want the repellent to reach. Some devices, such as sprays or powders, can be used to target small areas while others can be used to cover a much wider area.
  • Pet-safe ingredients: Any spray or powder you use must only contain non-toxic and pet-safe ingredients. The intention of an outdoor repellent spray is not for your cat to ingest it, but rather be discouraged by the spray action and its odor but it needs to be safe enough should any of the mist catch their eyes or mouth or settle on their coat. Some indoor sprays are designed to taste foul if licked or chewed so read the label to ensure the ingredients are safe and as natural as possible.

Different Types of Cat Repellents

There are several pet-safe repellents you can use to keep those felines out of your garden or to protect a problem area in your home:

  • Sprays: Formulated to be pet safe, a cat repellent spray is designed to deter a cat, through odor, taster or both. Outdoor sprays tend to be stronger than sprays for indoor use and will also be safe for use near plants. Sprayed over an area or a piece of furniture, a cat repellent spray should last for around three days before you need to re-apply, although you will probably have to repeat more frequently outdoors if it is raining or you water your plants. Wherever possible, look for a spray that uses natural or organic ingredients such as citronella, lemongrass, and peppermint.
  • Granules or powder: For a longer-lasting deterrent effect in your garden, granules or powder repellents are a good choice. These products come in a more concentrated formula than a spray and need to be applied directly to the soil. However, they tend to be more weather and water-resistant and can be effective on both domestic and feral cats for around 20 days.
  • Sound devices: One of the safest ways to repel unwanted feline attention in your garden is to use a sound or ultrasonic cat repellent, that projects a high-pitched sound that only those pesky cats will hear. These battery-operated ultrasonic devices often use infra-red sensors to detect movement and trigger the noise.
  • Motion activated: If there’s a lot of feral cat activity in your yard or garden, then a motion-activated device could be just the ticket. These devices act like a water sprinkler when the sensor is tripped, delivering a sudden burst of harmless water to shoo the feline intruder away.
  • Cat mats: Cats don’t like sudden or unusual noises and sensations and with a cat repellent mat, once they step on it, it makes a sound to scare them away. Harmless and versatile, you can buy these cat mats in strips to put in all the places you think cats are frequenting, such as along lawn borders and garden beds, and they can also be used inside. Alternatives to sound mats include scat or prickle mats which create a safe spiky surface most cats simply don’t like to walk on.

Ways to Use Cat Repellents

A cat repellent is going to help you keep unwanted cats away from your garden as well as control the behavior of your cat when they are inside your home. Using a cat repellent in the flower borders or at the edge of your lawn is going to help prevent feral cats using your garden as a toilet or digging up your plants. And adding a motion-sensor repellent or even a cat mat by the walls, fences, or entry gates is more likely to scare them away before they even come on to your property. Inside your home, an indoor cat repellent spray can be used on your soft furnishings, beddings, and carpet to deter your pet from scratching and clawing at your furniture. And, if you want to create a few cat-free spaces in your home, using a cat repellent such as a spray or mat can ensure your kit will stay on the other side of the door.

Whichever type of device you opt for, always fully read the instructions before using your new cat repellent to ensure it is effective and safe – for both humans and cats.

Best Cat Repellent FAQ:

Q: Are cat repellents safe around my pets?

A: As long as the cat repellent doesn’t use harmful ingredients or materials and you follow the instructions carefully, your pets will be safe around them. But you do need to take sensible precautions, for example, not using a cat repellent spray anywhere near a fish tank where the spray could enter the water and not using repellents near any very young pets. To be safe, always ensure any repellent spray states pet-safe and non-toxic on the packaging and opt for natural ingredients if you can. Always monitor your pet’s response to the cat repellent to ensure they are not being put under excessive stress, especially if they are of the more anxious sort. Cat repellents should be safe for all animals and shouldn’t have any element of cruelty to them – in short, they should safely discourage and do no harm.

Q: What smell will repel cats?

A: Cats can be sensitive creatures in many ways, and their heightened sense of smell can mean certain scents will trigger a ‘I’ve got to get out of here’ reaction. Smells your feline has a distinct dislike of include citrus aromas, especially orange, lemon and grapefruit, all of which are particularly repellent to cats. Other smells your cat really doesn’t like include lavender and geranium, as well as pepper, rosemary, mint, eucalyptus, and pine. But be careful and do your research as some natural ingredients – including lavender and mint – can actually be toxic to cats.
