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.

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 Chewy • Jul 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 Chewy • Sep 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 Chewy • Mar 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?

My cat has sprayed in certain places in my living room, and since I have plugged it in, she has not done a thing! I have had it for almost 2 weeks now. She seems happier and more loving, too. I hope this continues. If it is working and not just a coincidence, I plan on stocking up on refills.

The description says 2 refills, but if you zoom in on the image of the box, it does say that it only contains one refill. However, the product does work great. We used to use the multicat formula (also highly recommend), and decided to try this one now that we only have one cat. He noticeably perked up and his appetite improved within a day. It does leave an oily residue on the wall above the diffuser that isn't usually visible but some little insects get stuck in it; this has been true of other brands that I've tried as well, and I'm fine with wiping off the wall every so often if it's helping my cat. I just wouldn't plug it in under any art or curtains that could be damaged.

Better value

Keeps 2 of my cats from mega hissing & growling. Still some fighting but not as frequent. Less expensive than Feliway

Seems to be helping

My kitty is REALLY an anxious boy. Not sure if it’s my imagination but this seems to have helped him relax just a bit.

Leaves gross oily residue all over the walls

Not sure how well it worked for my two cats? They seem the same. Leaves messy oily residue all over the wall that's a pain to try and clean! I do like the diffuser

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.
