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?

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.

didn’t do much

I was advised by one of Chewy’d vets to use this due to my cats not getting along anymore despite them being best friends when they were younger. I used up the entire container and while it didn’t do anything bad, it didn’t contribute to any behavioral changes, my older cat still beats up my younger cat when she is in a bad mood, and she still acts exactly the same as before.
