About Comfort Zone Cat Calming Diffuser

Curb Stress in Your Cat

Just like people, cats behave differently when stressed. Comfort Zone products help relax your cat to curb stress-related, disruptive behavior so your cat can feel and behave her best.

24/7 Behavioral Support

Place one Comfort Zone Calming Diffuser in each of your cat’s favorite rooms for a happier, calmer cat.

Promotes Positive Behavior

The trusted, drug-free mist in the Comfort Zone Calming Diffuser helps reduce stress and promote positive behavior in your cat. Use it to help your cat adapt to life changes like a new baby, new pet, house guests, routine shifts and more.

How it Works

The Comfort Zone calming mist dispensed by the diffuser contains pheromones that mimic a cat’s natural feline facial pheromones (FFP). These are the same pheromones your cat would leave behind when head bunting you or rubbing her face on the furniture, and they signal to your cat that a place or object is safe and familiar. Using the diffuser can help make new objects or places feel more comfortable—just like one big kitty face rub spread across the entire room!

How to Use

Always use the diffuser properly and with the vents facing up. Leave four feet of space around the diffuser and avoid plugging it under shelves, behind furniture or near vents and windows for best results. Replace the refill approximately every 30 days or earlier if you notice it is empty.

Vet Recommended

Provides behavioral support for cats 10 months and older when used as directed.

Improved Behavior

The diffuser helps reduce stress and promote positive behaviors, with noticeable improvement in as little as two weeks.

Pheromone Technology

Comfort Zone makes a full line of pheromone products to help your cat feel better.

Promotes Relaxation

The calming mist signals a feeling a safety to your cat, lowering stress levels and promoting relaxation.

About Comfort Zone

Comfort Zone is dedicated to helping cats feel safe, calm and happy using signals they naturally understand. They make a wide range of products designed to promote positive behaviors and lower stress in cats. Their drug-free calming solutions can be used in and around the home or on the go. Take Comfort Zone anywhere your kitty needs to feel relaxed, safe and stress-free!

Questions & Answers

26 Customer Questions

it says this item comes with a refill... Does this mean there is a bottle already attached to the defuser? OR is the refill bottle the first one you put on the defuser...? in other words is the starter kit a 30 or 60 day supply?
Answer by ChewyJul 09, 2019
The single pack comes with 1 diffuser and 1 bottle.

I have a two year old cat that bites and loves to attack us. Ears back, back arched, but purring, at the same time. He is a rescue that the vet thinks was feral. Will this help that sort of behavior? Thank you.
Answer by ChewySep 21, 2019
While many pet parents have reported success using Comfort Zone to stop unwanted behaviors like scratching and biting, additional training and stimulation may be needed to completely curb the habit.

What’s the difference between the calming and the multi cat formulas?
Answer by ChewyMar 31, 2021
The calming formula is better for pet owners calming a cat with spraying or scratching issues, while the multicat formula helps eliminate conflict and tension among cats.

What is the difference between the old and new formula?

Sprays wall

Three times now I have found where there has been oily residue sprayed above diffuser on the wall. Covers about 4 ft up. I will not buy this again. Not sure what it was doing for the catitude in the house either. Disappointed.

Saved my cat!

I only have 1 cat. but she was becoming aggressive. After lots of $$ testing for illness, found she was very healthy. So, if I couldn't curb the aggression, I was afraid I would have to put down a perfectly healthy & young cat. (couldn't farm her out if she couldn't be trusted). This stuff worked wonders!! I keep 3 in the house, and I can always tell when one is running low.

Happy kitty again!

I had tried this on a cat years ago and it didn’t do a thing, but with Ziggy it was instantaneous! As soon as I plugged it in his whole demeanor changed and he went back to being the purring, non biting, happy kitty we remember! Wish I tried it when he first started showing bad behavior! Highly recommend!

Pretty messy

I just set this up and after 24 hours there's residue all over the mirror above it. the residue goes up at least three feet. I wouldn't want to see what it does to painted walls or curtains over time. On the plus side (?) the residue trapped a fruit fly.

Wishful thinking

Unfortunately these did nothing for either of my Bengals. I was super excited when I found them in store & couldn't wait to get home & plug them in. To my surprise, there was absolutely no change in behavior. No calming effect whatsoever. I've had them plugged in for 3 weeks now. Given they only last a month, I don't see anything changing within the next week. It should have already happened. I'm totally bummed....

It didn’t work for my pet! Return process is complicated

I give it a try to my cat in order to calm her down. After almost 1 month of trying it I didn’t see any improvement and there’s no return option in the order website. I wish if there’s one. Thank you!

Works but smells..

We had one on each floor. My cat did seem less stressed but the upstairs one started to smell like it was burning. We threw it away. The downstairs one started to smell the same way after 3 months. I threw it away also. I just canceled my autoship of refills.

Works Good

This works well in a bedroom size room, like an 8x10. You'll need 2 in a room that's larger, like a living room, entertainment/mancave size room.

no more stressed cat!

I recently moved and my new roommate has a dog, my cat had never lived with a dog before and was very stressed. Her fur was starting to fall out in clumps so I ordered this as a last ditch effort before going to a vet and it’s done wonders! She’s more friendly than ever before, purrs a lot, curious instead of terrified and has been willing to check out my roommate instead of cowering in my room! It does take up the whole outlet which is pretty much the only downside I can think of. Her happiness is well worth the monthly refills!

Works for me!

I bought this item hoping it would help with stress for my elderly cat as we brought a new cat in a year ago. About 3 months ago my older cat started peeing on our fresh laundry, the floor mat, and my couch! I took him to vet to check for UTI but nope. I bought this plug in and not even joking he hasn't peed on anything since we got it. We ran out for a month and I noticed he peed on couch one time and we bought more and hasn't happened since! I'm crossing my fingers it continues.
