A lot has changed since this piece was first published in 2023. In the last few years, the market has exploded with new brands and types of diffusers, including gel, portable, and stick diffusers. With an ever-growing interest among cat guardians, we decided it was time for another look.
This guide was largely informed by in-depth research and veterinary input. To learn more about cat pheromone products and how they work, I reviewed several scientific studies on the use and efficacy of cat pheromone therapy. I also referenced studies on pheromones in multi-cat households and pheromones for stress during transport.
Based on these findings, I purchased several sprays and diffusers for testing at home. Since it’s hard to measure tangible results, I focused on other important criteria. The products featured here come from reputable brands in the pet space. I prioritized products clinically proven to be effective and those recommended by veterinarians. I also considered product design, the amount of pheromones dispensed, and cost. Finally, I considered the experiences of other cat parents.
What Are Cat Pheromone Products?
Cats have glands on their heads, cheeks, paw pads, and tails that release natural “feel-good” chemicals called pheromones. These odorless signals allow cats to communicate and mark objects as safe and familiar. This is why your kitty likes to head-butt you. It’s their way of saying, “This is my human—they are safe.”
Pheromone diffusers and sprays mimic these natural cat-appeasing pheromones to calm feline nerves. In turn, they should curb stress-induced behaviors like excessive vocalization, scratching, hiding, urinating outside the litterbox, and fighting. They’re often used in vet clinics and shelters to help cats relax. Synthetic pheromones won’t work for every cat, but many cat parents report noticeable differences in their pet’s behavior after using them.
You’ll find two types of pheromones used in these products. The feline facial pheromone is useful for general stress and calms cats on an individual level. And the maternal cat-appeasing pheromone (FAP) helps keep the peace in multi-cat homes where fighting is a problem.
Who Are Pheromone Diffusers and Sprays Good For?
Pheromone products are species-specific—meaning they won’t be detectable or useful for dogs, humans, or other pets. But they’re completely safe to use around other animals who share your cat’s space. Pets and small children should be supervised around them, though.
Pheromone products may be helpful for:
- Cats with separation anxiety
- Multi-cat homes with constant fighting
- During travel
- Trips to the vet or groomer
- Introducing new cats to each other
- Cats with situational stress (e.g., fireworks, storms, noisy house guests)
- Curbing destructive behavior caused by nerves (e.g., scratching and urine marking)
- Cats experiencing stressful changes to their environment (like moving or remodeling)
Potential downsides of pheromone products include:
- They can be expensive (especially if used long-term and in multiple rooms)
- Some users report malfunctions like diffusers melting, leaking, or leaving oil stains on walls
- Some sprays have an off-putting scent
- Not as effective in large open spaces
- They may not work for your cat
For Dr. Melina Grin, DVM, the results are largely positive. “I use the Feliway spray on towels and blankets during stressful events. It helps with carrier confinement and car rides,” she says. “I also spray Feliway on my work clothes when I’m meeting anxious cats at the clinic.”
Dr. Grin notes that the Feliway diffuser reduced inappropriate urination for a few of her clients. “It has also dramatically benefited clients who foster kittens and was recently instrumental during kitten-cat introductions,” she says.
Cat parents should have realistic expectations about the effectiveness of these products. They often work best alongside other calming tools, such as calming treats, anxiety vests, calming beds, and help from a professional behaviorist or trainer. It’s also advisable to consult your vet for ongoing anxiety to rule out an underlying medical condition.
Types of Cat-Calming Pheromone Products
Synthetic cat pheromones can take a few different forms. The type that’s best for you will depend on how you plan to use it. For instance, consider whether your cat needs 24/7 nerve control, or their stress is more situational. Also, consider whether you’re trying to reduce general stress or if you need to calm inter-cat tensions and fighting.
- Sprays: Because they’re portable, sprays make the most sense for stress during travel. Sprays are better for situational stress and reducing stress in a specific area of the home, like a litter box or feeding station.
- Diffusers: For cats who need round-the-clock relaxation, diffusers make a better choice. These continually waft calming pheromones across an entire room.
- Collars: Since they go wherever your cat goes, calming collars make sense for kitties who go outside
The 9 Best Pheromone Products for Peaceful Cats
Our rankings are determined by a variety of factors. Each cat has different needs and preferences, so while the Feliway Optimum is our top choice, it may not be ideal for your unique cat.
To help you choose the right pheromone product for your cat, we’ve broken down our recommendations by diffuser type, cost, the circumstances under which they work best, and other key considerations.
#1 Overall Best: Feliway Optimum Enhanced Calming Diffuser
In the world of cat pheromone products, Feliway is by far the best-known and most reputable. In an earlier version of this piece, I tested the brand’s single-cat “Classic” diffuser, which releases the feline facial pheromone. Feliway also offers a multi-cat version to relieve tension among feline housemates.

In the years since this article was first published, Feliway has released another model: the Optimum Enhanced diffuser, which combines the best of both worlds. It’s designed to ease both general stress and help diffuse inter-cat tensions. A lot of Redditors sing its praises and report tangible results with the Optimum.
It’s a minor quibble, but I found this diffuser rather heavy, and it sagged in the looser outlets of my older home. Also, keep in mind that if you have to purchase several diffusers to cover a larger area, it will drive up your costs considerably.
What We Liked:
- Feliway is a trusted brand that conducts clinical trials
- Helps with both individual stress and inter-cat conflict
- Many users report improvements after a week of use
What We Didn’t Like:
- Some users reported issues like leaking or heavy sagging in outlets
#2 Runner-Up: TheraPetMD 60-Day Cat Calming Diffuser
TheraPet is a newer product that’s been receiving some attention. It emits the feline facial pheromone (2%) and covers up to 700 square feet. It’s more affordable than Feliway and comes with a spare vial. You can also purchase a two-pack for even more savings (just $23 per diffuser!) Each refill lasts 30 days.

The cute duck design adds a whimsical touch. You can turn the unit on and off by pressing in the duck’s bill. A blue indicator light turns on when the diffuser is in use.
Despite its promising features, a few issues put the TheraPet in our runner-up position. First, the brand is relatively new, which means long-term effectiveness has yet to be fully evaluated.
Additionally, we found the marketing misleading; the brand claims this diffuser features a “2-in-1 pheromone combination,” which suggests the presence of multiple pheromones. I reached out to the brand about this and was informed that the 2-in-1 combination actually refers to a blend of one pheromone type and the inert carrier (isoparaffinic hydrocarbon). This confusion could detract from the product’s overall credibility. Though I do appreciate the brand’s timely and clear communication.
What We Liked:
- Cost-effective and more affordable than competitor Feliway
- Spare refill included
- Cute design
- Can be turned on and off without unplugging
- Indicator light tells you it’s running
What We Didn’t Like:
- Newer brand, without the long-standing credibility of a brand like Feliway
- Misleading marketing regarding the “2-in-1” pheromone combination
#3 Best Budget Diffuser: ComfortZone Cat Calming Kit 2-Pack
Pheromone diffusers and sprays aren’t cheap. If you need them in several rooms, you could be looking at steep recurring costs.
Liz Coleman / Cats.com

Liz Coleman / Cats.com
Whether you’re on a budget or looking to buy multiple diffusers, Comfort Zone offers an affordable option. For less than $32, you get two diffusers and two refills. This set is economical for people who need diffusers in multiple rooms or want a replacement on hand.
Comfort Zone contains 5% pheromones, which is one of the highest concentrations of the diffusers listed here. According to the company, most cats will see improvements in about two weeks.
What We Liked:
- Affordable option
- Higher pheromone composition
- Prongs can rotate
- Safety shutoff feature prevents overheating
What We Didn’t Like:
- Some reviews mention overheating and a burning smell (I did not observe this)
#4 Best Spray: Feliway Classic Happy Cat Calming Spray for Cats
Whereas diffusers are location-dependent and deliver continual calm, sprays are ideal for situational stress. They’re portable, and you can use them in specific areas, like a carrier or a cat bed.
Liz Coleman / Cats.com
Liz Coleman / Cats.com
Liz Coleman / Cats.com
Feliway’s Classic spray is clinically proven to reduce destructive scratching and urine spraying in 9 out of 10 cats. To spare your furniture, spray 8-10 pumps directly onto the object your cat is scratching or marking. The effects should last about four to five hours. It’s also a good choice for traveling with your cat by car. I always spray my cat’s carriers 15 minutes before we leave for the vet.
One complaint we had was its fairly strong smell.
What We Liked:
- Allows for targeted calm
- Proven to reduce signs of stress in cats
- Ideal for situational stress (e.g., trips to the vet, visitors)
What We Didn’t Like:
- Strong smell
#5 Best Budget Spray: ComfortZone Spray & Scratch Control Spray
While Feliway takes our top spot for the best spray, this ComfortZone spray is a good budget option. It costs about $0.27/ml (vs. $0.42/ml for Feliway). Plus, it’s available in a larger 4-ounce bottle for even greater savings ($0.21/oz).

A common complaint regarding sprays is their noxious smells. This spray is perfume-free and has virtually no smell. This makes it a smart choice for folks or cats with sensitive sniffers. It would also be a good pick for spraying directly on furniture since it won’t leave a lingering smell.
ComfortZone says you should notice changes in your pet’s behavior in about 1–2 weeks, although some cats may take up to four weeks. There were some complaints about bottles leaking or defective nozzles, but I found it worked just fine.
What We Liked:
- Contains 15% analogue of feline facial pheromone
- Affordable
- 90-day money-back guarantee
What We Didn’t Like:
- Some users reported leaky or faulty bottles
#6 Best Portable Diffuser: Sentry Behavior Portable Calming Diffuser for Cats
Sentry specializes in behavioral solutions for pets and debuted this portable diffuser in 2023. With its plug-free design, it’s a versatile product that’s ideal for travel. The Sentry diffuser is lightweight and can go wherever you and your cat go, including the car. One user reported they put this diffuser in the car a couple of days before trips to the vet. It’s also a convenient choice for homes with limited outlets.

The Sentry portable diffuser includes a plastic stand and one disposable cartridge with a jelly-like substance. It’s easy to use; just remove the foil cover and slide the cartridge into the holder.
The package says this contains 3% pheromone & 97% inert ingredients. But it doesn’t specify which type of pheromone or what the inert ingredients are. I inquired with the brand about this and was told that the product contains a proprietary formula and that they could not release the ingredient list. I would prefer more transparency with this information.
The Sentry diffuser has a subtle floral fragrance, but I only notice the smell when I put my nose right up to it. Refills come in two-packs and cost less than $10 each (vs. the Optimum refills, which are a whopping $26 each!)
What We Liked:
- Portable, no need for a power outlet
- Convenient for travel
- Affordable refills available
What We Didn’t Like:
- Lack of ingredient transparency isn’t ideal
#7 Best Gel Diffuser: Virbac Zenifel Gel Diffuser
The Zenifel is another portable diffuser. It’s made by Virbac, one of the most reputable manufacturers of veterinary pharmaceuticals. Virbac develops products alongside researchers and scientists and follows stringent manufacturing protocols to ensure safety and efficacy.

This diffuser contains 6% feline facial pheromone. It also includes 0.5% catnip extract for extra feel-good vibes.
One of the biggest advantages of this diffuser is its longevity. The brand says it should last up to two months, so you don’t need to worry about replacing it as often. The Zenifel covers up to 750 square feet (a touch more than most products). It also has a discreet design that resembles a candle.
There is a slightly minty smell to this, but it’s only detectable at close range. Some users said their cats loved the smell and catnip so much that they wanted to lick the container. Be mindful of where you place it, and keep it out of your pet’s reach.
What We Liked:
- Virbac is a reputable and trustworthy brand
- Doesn’t have to be plugged in
- Lasts for two months
- Contains catnip extract for extra appeal
- Discreet design
What We Didn’t Like:
- Once it’s unsealed, you can’t close the lid to extend use
#8 Best Reed Diffuser: Signs SecureCat™ Home Stick Diffuser
This is one of the most unique pheromone products I came across. If you prefer an aesthetic solution to feline stress, this reed diffuser might appeal. It was developed by SIGNS Labs, a French research lab focused on creating pet pheromone products.
Liz Coleman / Cats.com
Liz Coleman / Cats.com
Liz Coleman / Cats.com
This set includes a glass container, eight sticks, and a bottle of liquid pheromone solution. To use, fill the glass vase with the solution and insert the sticks. The liquid should diffuse over 30 days and covers up to 649 square feet. Once the glass is empty, discard the sticks and replace them with a refill kit.
The pheromone solution contains 2% analogue of feline facial pheromone. Up close, the liquid has a mildly alcoholic smell. But I didn’t notice any scent from the reeds themselves after leaving them in the container for several hours. It’s worth noting some users did report an unpleasant smell, though.
If your cat is curious and tends to fuss with new objects in the home, be mindful about where you set this. If knocked over, the liquid could spill and make a mess.
What We Liked:
- Aesthetic design
- Doesn’t require an outlet
- Backed by years of research
What We Didn’t Like:
- Refills are expensive: kits with liquid and reeds are $28
- It can spill, and you need to be careful about placement
#9 Best for Separation Anxiety: Zesty Paws Calming Diffuser for Cats
This sleek Zesty Paws Calming Diffuser emits feline facial pheromones (4%). It covers up to 1,000 square feet, making it suitable for larger spaces. Its nebulizer technology works without heat, so it’s also a safe option.
Liz Coleman / Cats.com

Liz Coleman / Cats.com
A major selling point of this diffuser is its adjustable diffusion level. You can control the mist setting to low, medium, or high, depending on your cat’s needs. If your cat suffers from separation anxiety, you could crank up the pheromone levels a few hours before your departure. Just remember that separation anxiety is complex, and while this diffuser could help, your cat may need additional calming aids.
The pheromone solution has an orchid fragrance. I left the diffuser set to level two for several hours and found the scent very subtle and pleasant.
What We Liked:
- Covers large areas (up to 1,000 sq. ft.)
- Adjustable diffusion levels
- Sleek and modern design
- Pleasant orchid mist fragrance
- Safe, heat-free dispersal
What We Didn’t Like:
- Will only last 10 days if used consistently on the highest setting
Types of Cat-Calming Pheromone Products
Synthetic cat pheromones can take a few different forms. The type that’s best for you will depend on how you plan to use it. For instance, consider whether your cat needs 24/7 nerve control, or her stress is more situational. Also, consider whether you’re trying to reduce general stress, or if you need to calm inter-cat tensions and fighting.
- Sprays: Because they’re portable, sprays make the most sense for stress during travel. Sprays are better for reducing stress in a specific area of the home, like a litter box or feeding station.
- Diffusers: For cats who need round-the-clock relaxation, diffusers make a better choice. These continually waft calming pheromones across an entire room.
- Collars: Since they go wherever your cat goes, calming collars make sense for kitties who go outside occasionally.
Frequently Asked Questions
Does pheromone spray work for cats?
For some cats, yes—but not all. Studies have shown that pheromone products can help lower feline anxiety. But difference in environment and individual personalities can lead to varied results.
What are the side effects of pheromone diffusers or sprays?
Pheromones are natural and safe. Cats use them as a way to communicate. These are not a sedative nor a drug of any kind, so they do not have side effects. However, don’t allow cats (or toddlers) to ingest these products.
How long does cat pheromone spray last?
Typically, sprays will have an effect for 4-6 hours. After that time, they’ll need to be reapplied. Pheromone diffusers, on the other hand, work around-the-clock.
Did you test TheraPetMD?
Hi,
We’re currently testing it for an upcoming article update
Thank you for your information regarding Feliway Diffusers. I just bought 2, Classic & Optimum. I have 1 cat that started overgrooming her belly. Concerned with the Diffusers starting a fire.
We have tried Therapet and Feliway and I’m interested in possibly trying Wag & Whiskers. Wanted to see if you tested it.
Can different ones be used together?
Generally yes different cat pheromone products can often be used together, especially different formats like a diffuser plus a spray or collar, as long as you follow the manufacturer’s directions. VCA notes that cat pheromones come in diffuser, spray, and collar forms, and FELIWAY specifically says its Classic and MultiCat refills/diffusers are compatible.
