The 10 Best Cat Deterrent Sprays (According to User Feedback and Reviews On Reddit, Amazon, And Chewy)

My cat, Sunshine, loves to explore, and when she doesn’t get enough time to roam, my furniture takes the hit. That was why I  got some of the best cat repellent sprays, which changed the game.

Keeping an adventurous cat is an extreme sport.

One minute, they are resting peacefully in their crib; the next, they are walking around the yard, scratching the furniture, or digging into the couch. This can be tiring. I get it. 

To help fellow cat parents, I reviewed the best-selling and top-rated cat repellent sprays on Amazon and Chewy.

What should I consider when choosing the best cat deterrent spray?

Here are some factors to consider when searching for the best cat deterrent spray for your cat in descending order of significance:

• Behaviour
• Location 
• Coverage area and application rate
• Surface of application
• Smell 
• Age of the cat

Behaviour 

Picking the best cat deterrent spray starts with knowing why you need it, and this depends on the cat’s behaviour. Understanding its behaviour helps you understand the root causes and choose a spray that targets that specific issue. 

For instance, if your cat keeps peeing in a particular corner instead of using the litter box, using a deterrent with a repulsive odour to cats will do the trick better than one meant for scratching. 

Location 

Another important factor to consider when choosing a cat repellent spray is the location. This helps you choose the right spray that works well for your problem. Outdoor sprays are meant to be water-resistant, long-lasting, and have a strong scent. On the other hand, indoor sprays are meant to be gentle on your cats and on equipment and furniture in the home. 

Coverage area and application rate

A good cat deterrent spray should cover a wide area without needing constant reapplication. This should be a rule when choosing a cat deterrent spray. The larger the space or the more frequently your cat visits the spot, the more you’ll need a spray with long-lasting protection and efficient spread.

Smell

Cats have a very sensitive sense of smell, about 14 times stronger than that of humans. So, smell plays a huge role when choosing a cat deterrent spray. To pick a solid deterrent spray, go for the ones that smell like a huge turnoff to cats. As long as it doesn’t affect their health, it’s good to go. But remember, if you’re using it indoors, go for a relaxed smell that wouldn’t make your home unbearable.

Age of the cat

Not all cat deterrent sprays are suitable for cats in all age groups. Some deterrent sprays work better for kittens while some are more suitable for adults. The age of the cats also helps you understand the approach to take when spraying. Kittens are more inexperienced and are just learning boundaries, so they require gentler approaches and formulas. On the other hand, seniors are more experienced, so they require solid and more consistent deterring. 

Surface of application

Your surface of application matters as much as the cat deterrent spray itself. You don’t want to use sprays that incur losses and damage your properties. Some deterrent sprays have toxic elements that can damage delicate surfaces like wood and leather, while others are designed for only specific surfaces.

Are there DIY options for cat deterrents?

If you’re not ready to buy a factory-produced cat deterrent spray, this section is for you. I found some DIY options on Reddit, and they sound pretty cool. 

Here are nine of them:

• cat sticky tape
• baking sheets
• tin foil
• cat grass
• neem oil
• Oil of mint
• Crystals of peppermint 
• lemon rind
• Orange oil

These options are collated from users’ experience on Reddit, so ensure to verify the safety of each method before trying it. 

Cat sticky tape

This involves putting an adhesive tape on surfaces you want your cats to avoid. This works well because most cats do not like sticky paws. So, the idea of stepping on sticky tape might irritate them and scare them away. 

Materials needed:

• Thick double-sided tape.
• Clear packing tape.
• Scissors
• A flat surface (like cardboard or plastic) to pre-cut pieces if needed

How to put it together:

• Cut equal lengths of single-sided tape and packing tape.
• Stick the single-sided tape down with the sticky side up (you can use small weights or tuck the ends under an object to hold it in place).
• Press the packing tape on top, sticky side facing out, to create your own double-stick effect.
• Replace the tape every few days or once it collects too much dust and fur so it will remain sticky.

Baking sheets

If you want to keep your cats away from your countertop, this one’s for you. Cats hate sudden noises and unstable footing, and this is exactly what happens when they fall from your countertop to a baking sheet. They immediately associate jumping from a countertop with the unpleasant experience, the rattling sound of the baking sheets. 

Materials needed:

• 2–4 lightweight metal baking sheets.
• Countertops, shelves, or surfaces where your cat frequently jumps.

How to put it together:

• Place the baking sheets close to the edge of the surface, just enough that they may shift or make noise when stepped on.
•  Leave them there consistently for a few days or until your cat avoids the area.
• You can layer them slightly or leave them spaced, depending on the size of the sheets. 

Tin foil 

Cats dislike the crinkle texture of tin foil or the sudden sounds it makes when they walk on it. It feels unstable and unpleasant, which helps deter them from climbing or walking over areas covered with it. However, if your cat is a patient one, tin foil might not be the answer as it might learn to get used to the sound. 

Materials needed:

• Standard kitchen aluminum foil
• Scissors (optional for shaping)

How to put it together:

• Cut foil sheets to fit the no-go zones your cat loves to access (e.g., couch arms, counters, plant bases).
• Lay the foil flat and smooth, or scrunch it lightly.
• Replace as needed when it gets torn or loses its crispness.

Mint oil

Most of the industrial cat repellents we touched on earlier in the guide are made of essential oils like peppermint oil. Why? This is because cats find the smell of mint repulsive, and they do all they can to avoid it. However, you have to make sure it is done in a well-ventilated place to avoid sensitive cases like skin irritation. 

Materials needed:

• 1 drop of peppermint essential oil
• 30 mL (about 1 ounce) of water
• A glass spray bottle 

How to use:

• Add 1 drop of peppermint essential oil to the spray bottle. 
• Fill the bottle with 30 mL of water.
•  Shake well to mix.

• Lightly spray the solution on areas you want to deter cats from, such as furniture or doorways.
• Do not spray directly on your cat or areas where they frequently rest.

Crystals of peppermint 

Peppermint crystals, also known as menthol crystals, are solid compounds obtained from peppermint oil. That means they are also as repulsive as the oils to your cats and can serve as a good deterrent item. When in an area, cats avoid the place because of its strong minty scent.

However, to avoid sensitive reactions like skin irritations, make sure it is used in a well-ventilated environment. 

Materials needed:

• Peppermint (menthol) crystals
• Small sachets or breathable fabric bags
• String or twist ties 

How to use:

•  Place a small amount of peppermint crystals into each sachet or fabric bag.
• Tie the sachets with a rope or string.
• Position the sachets in areas you wish to deter cats from, such as near plants, furniture, or entryways.
• Ensure the sachets are placed out of reach of cats and children.
•  Replace the sachets every few weeks or when the scent diminishes. 

Lemon rinds

If you’re looking for a 100% natural cat repellent and you don’t want to alter the scent of your home, then you should consider lemon rinds. Cats generally dislike citrus smell, and the smell of lemon, being a citrus, is strong enough to keep them away. 

Materials needed:

• Fresh lemons
• Knife or peeler
• Small containers or sachets (optional)

How to use: 

• Peel fresh lemons to collect the rinds.

Place the rinds near areas where you want to deter your cat, such as furniture, in between plants, or on countertops.

• Replace the rinds every 2–3 days, or when the scent starts to fade.
• You can also place lemon rinds inside breathable sachets or small containers to make cleanup easier (totally optional).

Orange oil

https://vm.tiktok.com/ZMB3TjtQk

Just like lemon, orange oil is made from orange, which is a citrus fruit. Smell or scent from this oil can be very repulsive to cats, and their first instinct is to leave wherever it’s sprayed. It is important to note that, like every other essential oil, orange oil should be applied in a well-ventilated area to prevent allergic reactions. 

Materials needed:

• Orange essential oil (100% pure if possible)
• Water
• Spray bottle

How to use:

• Mix 10–15 drops of orange essential oil with 1 cup of water in a spray bottle.
• Shake well before each use.
• Spray the mixture lightly on surfaces like furniture legs, plants (not directly on them), or baseboards.
• Avoid spraying on items your cat may chew or lick, and never apply directly to your cat.

What are the steps to follow to choose the best cat deterrent spray for your cat?

Choosing a cat deterrent for your cat can be quite challenging. This is because choosing the wrong spray can cost your cat’s comfort and health. To avoid falling into that, here are five steps to follow when choosing the best cat deterrent spray for your cat. 

Identify the specific behaviour:

Cat behaviours differ from one another, and it’s unadvisable to use a cat deterrent spray on your cat because you saw something online. Instead, identify the EXACT behaviour you want to curb. These behaviours include scratching, spraying, chewing, and any other behavior unique to your cat.

According to VCA Animal Hospital, it’s important to identify the behaviour and its underlying cause before picking a cat deterrent. 

Consider the  application area/surface 

Some deterrent spray causes damage to properties like furniture and fabrics. To avoid incurring losses, pick a spray that is neutral on the surface you’ll be applying it to. Also, the place you’ll be applying the spray matters a lot. Some deterrent works indoors but can’t stand the mildest breeze or rain that are prone to occur outdoors. 

Check the ingredients and ensure safety 

According to Chewy, it is important to know the ingredients in a particular deterrent before you get it. This helps you identify if the ingredients are safe to be used around your cats and in your home. Make sure you know you and your cat’s allergies and rule out deterrent sprays with ingredients that can trigger them.

Consult reviews and experts’ opinions on the sprays

Reviews don’t lie. Consult people who have used the products before you to note the effectiveness and side effects. Reviews help you find out more than what is written on the body of the spray. 

Test and monitor your cat’s response

The main goal is to elicit a response that drives your cats away from the sprayed place. However, some deterrents might elicit another response from your cats, and this can be dangerous if care is not taken. Carefully monitor your cats and take note of how they are responding to a particular deterrent spray.

 Conclusion 

Whew! We’ve come to the end of the guide, and I hope you enjoyed reading it as much as I enjoyed writing it. Now, for a brief recap, in this guide, we looked at:

• The best cat deterrent for our cats. 
• Things to consider when choosing a deterrent spray for our cats. 
• How to make some DIY deterrent tools and sprays. 
• Important steps to take when choosing a cat deterrent spray. 

While everything in this guide has been tested by real-life users and recommended by experts, always double-check with your veterinarian, especially if your cat has allergies, respiratory issues, or a history of anxiety. What works for one cat might not be safe for another. Goodluck!.

Frequently asked questions

Do cat deterrent sprays work?

Yes, cat deterrent spray works when applied properly. 

Do cat deterrent sprays affect humans?

Most sprays are safe for humans, especially if they’re made with natural ingredients like citrus or peppermint oil. However, some people may be sensitive to strong scents or essential oils, so it’s always a good idea to test it in a small area first or check the label for warnings.

Does cat deterrent spray pollute the air?

This depends totally on the product. Natural sprays made with essential oils are usually eco-friendly and safer for indoor use. But sprays with synthetic chemicals or propellants might contribute to indoor air pollution, especially in small spaces.
