Like humans, cats can get stressed out every now and then. It can be due to various reasons, like overstimulation, boredom, and changes to their environment. While you should address the cause of their stress first, you might also find yourself researching calming aids to improve the situation further or soothe them through an unavoidable situation, such as moving to a new home.
There are several products that you can use, and a pheromone diffuser is a particularly practical choice. This plug-in works by releasing calming pheromones into the air, which will help your cat to relax. Felines naturally produce different types of pheromones from special glands in their body. These are a form of communication that all cats use to interact with each other and as messages to themselves. Commercial diffusers use synthetically made versions of feline pheromones that aim to produce “happy” messages and feelings of comfort and safety.
So, if you’re searching for a product to help calm your cat, you’re in the right place, as these reviews will show you exactly what is available so you can figure out what works best for your anxious kitty!

The 5 Best Pheromone Diffusers for Cats
1. Feliway Classic 30 Day Starter Kit Calming Diffuser for Cats — Best Overall
| Longevity: | 30 days |
| Square Foot Coverage: | 700 |
Our choice for the best overall pheromone diffuser for cats is the Feliway Classic 30 Day Starter Kit Calming Diffuser for Cats. It is vet recommended and will help reduce signs of stress like spraying, scratching, and hiding. It covers 700 square feet, which means it will work in an apartment or a large room. It is unsuitable for homes with caged birds, though, especially parakeets and psittacines; since these birds have sensitive respiratory systems, inhaling the pheromone chemical could be hazardous to their health. This diffuser also comes in a multi-cat option, so you might consider this one if you have more than one cat.
Owners liked this product overall and thought it to be reliable.
- Vet recommended
- Covers 700 ft²
- Lasts 30 days
- Reliable
- Unsuitable for homes with caged birds
2. Comfort Zone Calming Diffuser — Best Value
| Longevity: | 30 days |
| Square Foot Coverage: | 400 |
The best pheromone diffuser for cats for the money is the Comfort Zone Calming Diffuser. The drug-free solution works to naturally calm your cat without affecting other pets and is affordable, as are the refills. The new and improved design leaves room in the outlet for other appliances or devices, which was a problem before.
When refilling, take care, as the contents have been known to spill. If this happens, clean it up immediately since it is poisonous and can cause skin irritation for humans and pets.
- Affordable
- Relaxes your cat without affecting other pets
- New design saves space in the outlet
- Prone to spilling
- Covers small area, only 400 ft²
3. ThunderEase Calming Diffuser — Premium Choice

It will help with undesirable behaviors like scratching, urine marking, separation anxiety, and dealing with visitors (human and animal). It lasts for 30 days of continuous use and covers 700 square feet.
Some owners complained of it leaking when they were refilling it. Since this product is incredibly flammable and harmful or fatal if swallowed, you must be careful when handling it.

While it does promise to last 30 days, some owners noted that it ran out faster, meaning more frequent changes, which cost more money. It also has quite a strong smell, so if your cat is sensitive to fragrances, there might be a better diffuser for them.

Buyer’s Guide: How to Pick the Best Pheromone Diffuser For Cats
When your cat is stressed, a diffuser emitting calming pheromones can help it feel safe in its environment. These products release synthetic pheromones that mimic the natural “feel-good” chemicals produced by cats to keep them calm and prevent stress-related behaviors such as scratching or spraying. There are different types of diffusers available, so it’s important to understand their features and benefits before choosing one for your cat. Here are some points to consider when purchasing a pheromone diffuser for your cat.
Coverage Area
Different diffusers cover areas of different sizes. The diffuser used should be appropriate for the size of the room or area in which the cat spends the most time. A diffuser that covers up to 700 square feet may be suitable for larger areas, while smaller areas may only need a diffuser that covers 200-400 square feet.
Longevity
Pheromone diffusers usually work for around 30 days before the pheromone bottle needs to be replaced. However, some diffusers may run out more quickly or last longer than expected. It’s important to check how often you’ll need to replace the refills and factor this into your budget.
Safety for Other Pets
Pheromone diffusers are generally safe for cats. However, it is not advisable to use pheromone diffusers for cats in homes with other animals. For example, some products can have adverse effects on birds, especially those with sensitive respiratory systems. It’s important to consult the manufacturer’s guidelines if you have other pets.
Ease of Use
Diffusers should be easy to install and maintain. Some products have additional features such as self-cleaning mechanisms, a rotating plug for better placement, or a compact design that requires less space. These features make the diffuser more convenient to use and allow it to fit into anyone’s life seamlessly.

Benefits of Using Pheromone Diffusers
Reduction of Stress-Related Behaviors
Pheromone diffusers are used to control various behaviors associated with stress, such as scratching, urine marking, or hiding. They are particularly effective during periods of transition, such as moving to a new home, introducing new pets, or dealing with separation anxiety. These diffusers have stress-relieving properties that may positively impact your cat’s behavior.
Drug-Free Solutions
Another great thing about pheromone diffusers is that they provide a drug-free way to soothe your cat. Most pheromone diffusers are safe for long-term use and are considered natural alternatives to potentially hazardous medicines.
Compatibility with Multiple Cats
If you have multiple cats, consider using diffusers designed for multi-cat households. These options effectively reduce territorial instincts, making it easier for cats to coexist in peace.
Frequently Asked Questions
What Are the Signs Your Cat Might Benefit From a Calming Pheromone Diffuser?
Your cat might be exhibiting undesirable behaviors like urinating outside their litter box, fighting with another pet, or scratching up your furniture. These are indicators that your cat is stressed or anxious.
- Change in mood
- Change in weight
- Excessive hiding
- Increased lethargy
- Increased vocalization
- Loss of appetite
- Vomiting
These signs can also point to a wide range of medical issues, so it’s important when you notice any of these signs to get your cat checked by the vet to rule out any underlying health problems.
Do Pheromone Diffusers Work?
Studies have shown that diffusers can help reduce anxiety-related behaviors and provide relief for cats suffering from mild signs of anxiety. Like humans, cats experience stress and anxiety in different ways, so a cat that is experiencing more severe signs might also need professional treatment.
Are Pheromone Diffusers Safe?
Yes, they are safe when used according to the manufacturer’s guidelines. Unlike a sedative or medication, pheromones don’t have to be ingested and metabolized. While pheromone diffusers are synthetic, they work the same way that naturally occurring pheromones do, which is to send chemical signals that trigger changes in the cat’s brain and behavior.
It’s still important to watch your cat closely when you start using a pheromone diffuser because every cat is different. Also, some diffusers have added scents, such as lavender and chamomile, which your cat might not like. Pheromones are species specific, so they don’t affect humans and are safe to use around older people and children. It’s vital that you don’t use out-of-date liquid, though, since it won’t have any effect and could be harmful to your cat.
How Do You Pick the Right Calming Aid?
The diffusers featured here are excellent products, but you can also try spray pumps, wet wipes, and collars. Each has its own benefits and drawbacks and won’t work for every cat, so it’s best to research them all.
The traditional diffuser is best for indoor use and will help prevent scratching and marking effectively. The pump is good for travel when used in your cat’s carrier to help your pet feel calmer and more relaxed. Collars can be good for cats that are going outdoors. There are also diffusers specifically for multi-cat households, which can help cats live more harmoniously together.
