Like many people, you’ve likely experienced anxiety at one point or another. And you’re probably aware that dogs can suffer from the condition, as well.

But did you know that cats get anxious, too?

It’s true. Although they have a reputation for playing it cool, our feline friends can indeed experience the uncomfortable—and even debilitating—effects of anxiety. In fact, a recent study found that 13.5 percent of pet cats showed at least one symptom of anxiety.

“Changes like a new home, a new family member, or just that annoying cat next door can cause unwanted, anxiety-related behaviors,” says Alexandra Rodriguez, a veterinary technician in South Carolina. “Some pet parents turn to pharmaceutical options, while others try pheromone diffusers.”

What Is a Cat Pheromone Diffuser?

Pheromone diffusers contain synthetic chemicals that mimic a variety of naturally occurring pheromones known to soothe cats. Like electronic air fresheners, they plug into standard electrical outlets and require periodic cartridge changes. 

These plug-ins are odorless—humans and other pets can’t detect the scent of cat pheromones. 

There are two different types of pheromone blends used for cat stress relief: calming pheromones and multi-cat pheromones. 

Calming pheromone blends imitate a cat’s facial pheromone. These pheromones are helpful for homes with one cat. 

“When your cat rubs their face on you or the furniture, they’re claiming their territory by releasing pheromones,” explains Rodriguez. “These pheromones help a cat feel safe and secure by giving them a sense of familiarity and belonging.”

Multi-cat pheromone solutions replicate the pheromones that a mother cat releases to soothe her kittens. 

“These pheromones help put cats at ease in the presence of other cats,” says Rodriguez. “Multi-cat pheromone diffusers are best used in homes with multiple cats who are experiencing tension or conflict.”

Cat Pheromone Diffuser FAQ

Do you have questions about cat pheromone diffusers? You’re not alone. Here are some helpful answers to the questions pet parents tend to ask most frequently.

Do pheromone diffusers work for cats?

Yes, studies have shown that cat calming diffusers can help reduce common anxiety-related behaviors in cats, including: 

For cats with mild symptoms of anxiety, a pheromone diffuser may offer significant relief. 

“In cases of mild anxiety, they may be sufficient to calm the cat alone,” says veterinarian Dr. Joanna Woodnutt.

However, like people, cats experience anxiety differently. Pets with more severe symptoms may need additional intervention. 

“Pheromone diffusers may not be enough for some very anxious cats,” says Woodnutt. “For these animals, extra calming tools and changes to the environment may be needed.”

Additionally, it’s important to note that anxiety symptoms can point to a wide range of underlying health issues in cats. 

“Be sure to get your cat checked out by a vet to rule out any potential health problems,” says Rodriguez. “Once your kitty is deemed healthy, you can try using a pheromone diffuser to help put them at ease.”

Are cat pheromone diffusers safe?

Yes, pheromone diffusers are generally considered safe for cats when used according to the manufacturer’s directions.

“The nice thing about pheromone diffusers is that they’re natural, and unlikely to do any harm. They can therefore be used for non-anxious cats, and for cats with on-and-off anxiety, without any risk at all,” says Dr. Woodnutt.

Though diffusers use synthetic pheromones, these “copycat” markers work the same way naturally-occurring pheromones do — by sending chemical signals that trigger changes in cat brains and behavior.

Unlike calming medicines or sedatives, pheromones — natural and synthetic — don’t have to be ingested or metabolized. So you don’t have to worry about any interactions or dosing recommendations. Pheromone diffusers are also safe to use around kittens. In fact, many use the same markers released by mother cats to soothe newborn kittens.

It’s still a good idea to keep a close watch on your cat when using a pheromone diffuser for the first time. Every cat is different, and some additives, like scent, may bother sensitive cats. If you notice any adverse reaction, discontinue using the diffuser and contact your veterinarian for guidance. 

Do cat pheromone diffusers affect humans?

No, in addition to being odorless and colorless, pheromones are species-specific. So using them will not affect pet parents at all. (Unless you count feeling better and less stressed because your cat is calmer!)

Some diffuser formulas incorporate copies of pheromones from multiple species of animals, so they can be used to create harmony in multi-pet households. So be sure to read the packaging to determine the right pheromone diffuser to fit your needs.

Cat Pheromone Diffuser Buying Guide

Cat lying on rug

There are a number of things to consider when selecting pheromones for cats. 

The most important factor is the pheromone blend. If you have a single cat, select a diffuser that uses calming pheromones. If you have more than one cat, purchase a multi-cat pheromone diffuser.  

Other considerations when shopping for cat pheromone diffusers should include:


There are a number of cat pheromone products on the market, some of which have been tested more rigorously than others. “Look for a brand that is clinically proven,” says Woodnutt. “Any brand that claims this should be able to back it up with actual scientific papers. If you aren’t sure whether to believe them, call and ask for them to send you some information. If they can’t, well, you have your answer!”


Pheromone diffusers have a wide variety of ranges. While some disperse pheromones throughout the entire house, others only cover one room. Consider your home and your cat’s symptoms when selecting a product. If your cat is only marking one room, for example, a single small diffuser might be appropriate. If you have a larger home or issues in more than one room, you will likely need a more powerful diffuser or several devices. 


Although cat pheromones aren’t detectable by humans, some diffusers contain added scents, such as lavender. While some may consider this a bonus, make sure you enjoy the particular product’s scent. 


Check to see how long the diffuser lasts. If you forget to change the cartridge, your cat may relapse into past behaviors, so choose a product that can go at least 30 days between replacements.  


Ensure that the product you purchase is designed specifically for cats. Dog pheromone diffusers are also available, but will have no effect on cats.
