Less Stress for You and Your Cat
Sometimes even the sweetest cats have behavior issues, with 42% of cat parents reporting trouble. Comfort Zone’s New 2X Pheromone Calming Diffuser and Refills can help ease the stress and manage no-no behaviors like urine marking and scratching. Using calming pheromones that mimic the natural pheromones cats produce when they’re happy, this drug-free solution makes cats feel secure and helps reduce stress-induced destructive behavi


How It Works
Comfort Zone Calming Diffusers gradually release pheromones into the air that mimic the friendly hormones cats produce when they feel safe. This drug-free intervention can help your cat feel calmer and more secure in his surroundings, so he won’t feel the need to scratch up furniture or go outside the box. Help him be a good cat by making him feel safe.
Improved Formula
Comfort Zone’s diffusers have been reformulated with an improved odor profile and twice as many calming pheromones as other leading brands. They’ve also been designed to provide a more consistent pheromone diffusion that lasts a full 30 days. Twice the pheromones and steady diffusion will help keep your cat feeling relaxed all day, every day.

What to Expect
Most cats begin to show improvement after two weeks of use, so give your cat a little time. The plug-in diffuser uses gentle heat to release a vapor that’s drug-free and safe for people and pets. Cats can smell it, but people usually won’t. There’s an automatic shut-off system to keep it safe and prevent overheating.
When to Use Comfort Zone
When your cat’s feeling stressed, Comfort Zone diffusers can help curb negative behaviors or even prevent them before they start. If you’ve moved or brought new people or pets into the house, or when you’re traveling or changing your cat’s routine, these calming pheromones can help him cope. They’re also great for easing vet-induced jitters and angry cat protest behaviors.

These used to be great.
By Moose on Jan 26, 2021
For a year we used these without any issues, but the last three bottles have gotten to the halfway point and started to stink terribly. The house smells like burning crayons. It isn't the diffuser itself as we replaced that and had the same experience until we added a new bottle of liquid. It's incredibly disappointing because our cat needs this product, it makes a huge difference in his life, but what good is a product that you pay full price for but can only use half of? We will find another brand of calming diffuser to try for our poor anxiety-ridden cat. Please note that this is not a complaint about Chewy, simply the product. Chewy was awesome and sent us free refills when we complained For a year we used these without any issues, but the last three bottles have gotten to the halfway point and started to stink terribly.

Well worth the money
By Amethyst on Feb 10, 2021
I have used the Feliway for years. It has helped. This is about 1/2 the price. Rumor has it that it works the same. I have found that my cats are much more relaxed when I use this. I highly recommend it... for generalized anxiety, some aggression and much less clawing of the furniture. Plus, the three of them just seem happier and more content. The one who has been aggressive has, in the past couple of days, gingerly begun to groom the other two.

Works for my household
By KimmyD on Jan 19, 2021
I have a 6 month old partially blind kitten that is terrorizing my 3 older cats with just wanting to play all the time. He has stressed out the 9 yr old sisters, so I thought I'd try this besides catnip treats. I bought the original and plugged it in under the kitchen table where the girls tend to hid from the kitten. I had it for the 30 days and it has seemed to keep all calm with occasional outbursts from the energetic kitten but the older cats are now calmer with him around. So I ordered this refill and I found the girls taking turns laying by the diffuser since refilling it. This one definitely works for our household.

I didn't think this would make much of a difference.
By Midge on Jan 4, 2021
My 6-year old cat developed a urinary inflammatory problem sparked by anxiety (and is a high-anxiety cat). During a flare-up, she will urinate blood and often relieve herself on the couch as a backup to the litter boxes. While I have a cover so it's protected, correcting the behaviour has been an issue, so I decided to try these plug-ins. I tried one in the room with her litter box and found that her anxiety only really spiked when it ran out. I added one near the couch and she hasn't tried to urinate outside of her litter box since then. These are a lifesaver! I don't know if they work for all cats, but mine seems to be enjoying the relief they provide. I'm thankful for this option!

This is absolutely effective!
By Bethel on Jan 13, 2021
I purchased this when I first brought my kitten home. My older cat really benefited from this with the new kitten. After 5 weeks, I noticed that the kitten had started biting and rough housing more, sending my cat into hiding.. I replaced the diffusers in my living room and upstairs bedroom and within an hour, the two cats were cuddling on the couch. They both are still playful but much kinder to one another. I've continued using this and it works so well that I now have it on my autoship.

This Really Saved Us!
By Diane on Nov 27, 2020
I wasn’t expecting any miracles but gave it a try anyway. My rescue cat couldn’t handle me fostering another kitten and was so scared that she hid in a room upstairs most of the time and wouldn’t engage in activities around the house even months after the kitten was adopted. A couple of weeks after I plugged this in she started to go into the dining room but wouldn’t come around the corner to the other rooms so I added two more in adjoining rooms and eventually she made her way throughout the entire house. Her behavior is back to normal and then some. She’s happier and calmer, and has even started sleeping in new places around the house where she wouldn’t usually go.

Perfect! Works!
By DogMomOf5 on Dec 19, 2020
I have 10 rescue cats in my house. Some are not so friendly and don't like other cats. We have a cat door so feral cats can also come in from the cold. This keeps cat fights out of my home. I strongly reccomend when you have at least 2 cats that don't get along.

expensive / refills do not last long
By Jackie on Feb 3, 2021
I think this product works. However I am removing one start due to the price. The refills need to be replaced often. This makes the product too expensive.

indoor cat was outdoor cat
By RenaeB on Oct 25, 2020
A little story about my cat will help others analyze whether their cat could benefit from this product. I am still testing out whether the product is effective. This is the second one I have bought because I ran out of the other refill and my cat walked up to it one day sniffing it like he realized something changed. I didn’t even think he acknowledged this was plugged into the room he stays in. I got it to try and see if it keeps him relaxed when I am away. He is a 15 year old mix with some breed that is known to be hyper. Since he is a senior cat, he does sleep more, but has very hyper moments and does get stressed when he needs attention.

Chewy has the Cheapest Price
By Sweetcat on Jan 24, 2021
Chewy has the cheapest price, I could find for the Comfort Zone refills. Pecto is a little bit pricey.
