Comfort Zone Multi Cat Calming 1 Room Bonus Kit, 1 Diffuser & 2 Refills

I bought this in sheer desperation after a cross-country move with my cat. He’s generally a pretty friendly guy and had never peed on anything before. We moved into a new house and he was clearly super anxious and withdrawn, not eating well, very jumpy. I tried calming treats, keeping him in his own room with his toys and bed at first, everything. Nothing worked. I bought these diffusers after his second time peeing in and destroying a $300 suitcase in one week. Plugged them in, didn’t expect much. Within about a half hour he came out to hang out with us and within the same day he was back to his old self. Ate all his dinner, started socializing with us again, and has not peed on anything since. They may not work for all cats, but definitely worth a shot if you’re at your wit’s end like I was. I wish they had a version of this for humans, lol.

Our cats have always done well with no problems with aggression, spraying and going in the litter box. Until we rescued another kitten is when the problems started. Our boys eventually calmed down but our girls got so aggressive with the kitten. I was so happy to have found this product because it is what saved my sanity. I use 4 plug-ins in the house and change it out every 3 weeks. If I wait to 4 weeks to change the diffuser my cats start acting out again. It worked so well that we were able to rescue another kitten with no problems at all.When I first purchased these plug-ins it only took 24 hours for my cats to settle down. The girls seemed more calm and the boys were more loving to our new kitten. After one week of using this product my cats both the girls and boys acted just like they did before we got the new kitten. They stopped spraying and used their litter box. We have never had any problems with the diffuser over heating and causing any electrical problems. When I first plug it in it does have a slight plastic like smell but then it disappears. It can get pricy to keep changing the diffusers every 3 weeks but it is well worth the money to keep all of our babies happy. The second kitten we rescued worked out well with our other cats and I believe that is because we were using the diffusers.We also owned birds and I was worried about the diffusers potentially harming them so I did not plug the diffuser close to my birds and have never had a problem. I am a very happy customer and would recommend this item to my fellow cat owners.

For the first 2 days or so there was a VERY strong smell. It didn't smell AWFUL, it was very powerful and kind of perfum-ish (still not a great smell though!!) I could smell it from every room in my apartment (it's not a huge apartment but it does have multiple rooms and it was in my living room and I started to smell it in my kitchen and had no idea where it was coming from, until I realized. My cats are extremely sensitive to smells so I was concerned. It did subside and has not smelled since. I know why it smelled, as it was warming up etc, but I've used another brand in the past and have NEVER had a smell, other than a slight smell that I can't explain that is not at all perfum-y but if you've used pheromones' before you likely know what I'm talking about. It does what it should do, it has helped with my 2 cats fighting over territory as they are preening one another more often and sleeping next to one another more often now. Would purchase again.

It worked for the cats but I had a reaction to them. I can’t use them sad because we really need these. Ughh

**Disappointing and a Waste of Money**I purchased the Comfort Zone Multi-Cat Calming 3-Room Value Kit on 7/20/26, and it was delivered on 7/22/26. I immediately put it to use as directed, placing the plug-ins in my cats’ playroom, living room, and the room where our new kitten stays. Unfortunately, I have to say this has been one of the worst cat-related purchases I’ve made.I purchased this product because we recently welcomed a new kitten into our home. My 16-month-old tabby (Cat #1) has not been happy about the new addition. She has been hissing and swatting at her sibling (Cat #2), and she becomes more aggressive when she goes near the door to the room where the new kitten (Cat #3) is staying. This behavior is completely out of character for her.After reading the positive reviews on Amazon, I was excited and hopeful that this product would help reduce her stress and help her return to her normal, happy self. Unfortunately, that has not been my experience.I followed the directions and used the product in multiple rooms, but I have seen absolutely no improvement in her behavior. On top of that, the product has a strange smell that I find unpleasant.For me, this product was a complete waste of money. I really wanted it to work and was hopeful that it would help my cats adjust to the new kitten, but unfortunately, I have not seen any noticeable difference.

I have not written a review on Amazon yet and I purchase items weekly often more. I am in shock at the effectiveness of this collar! I have a male 5.5 year old cat who was neutered as a kitten and has been my baby. He has always been a high strung cat and needy, constantly meowing wanting held or treats but he would sleep with me, cuddle on the couch etc. Three years ago my daughter moved back home and brought her small dog with her and my neighbors moved in with two non-neutered males next door. My cat began marking/spraying. I tried all the Feliaway products in the rooms and the collar. Of course made sure the letterboxes were cleaned twice daily, that he had no medical conditions etc. In the last 3 years the problem had gotten completely out of hand to the point that whenever he was let inside the house he started searching for his spots to spray and within a minute he would mark his territory and if left to continue would endlessly do so. He also was now very high strung and didn't even want much attention and never came to sleep in our room. We finally decided to try the cat prozac which he had been given for about a week and half. However, my vet gave me a capsule that I had to open and sprinkler the powder on his food. He is so finicky that I wasn't getting much in him despite my efforts at buying anything and everything to sneak it into. At this point it hadn't done ANY good! I decided to give this collar a try and THAT NIGHT my cat completely relaxed, he came and cuddled and laid by us on the couch, something he hadn't done in probably 6 months. As always now I watched his every move inside the house and it has been a week and half and he has not sprayed ONCE!!!! He eats all his food with the prozac in it too! He plays with the other cats. He is back to his old self again. I am so grateful for this product. I was going to have to keep my cat completely outside and that was not going to be easy. I will update my review once it has been 2 months

I love these! I don't have them plugged in all the time, but when a new cat comes into our household or when, for some cat reason, the cats get aggressive with each other, I plug them in for a month or two and things settle down. They are so simple to use, simply screw on a bottle and plug in, they don't take up the entire outlet so you can still plug in other devices, the design is modern and understated. They don't have a funky odor like some plugins I've used, so I like that. They usually last about a month so you have time to order more when you install the last ones. I use 3 at a time, one in each area where the cats spend a lot of time. They are very effective, taking cat interactions from fur flying fights to non-violent games of chase. That works for us!

I didn’t believe it would work but it is!!!!! We moved and where we live now is on a very busy intersection so my cats can no longer go outside so they started fighting all the time and the one took to peeing on the floor by the litter box and on any clothes left out. So my friend suggested me to get this and I cleaned the floor with an enzyme cleaner as per the directions and plugged in the diffusers on opposite ends of the house. They have no sound are small and discrete. I don’t smell anything funny and they look like any other diffuser. Would highly suggest and I will be buying refills! I have no more cat pee and the fighting is almost non existent!

Tengo una gata extremadamente nerviosa, recién adopté 2 gatos nuevos y se puso muy mal. Se escondía, se le empezó a caer el pelo, la veía muy decaída. Temí le fuera a dar PIF por estrés. Mi última esperanza era este producto ya había escuchado de las feromonas sintéticas. Debo admitir que sí funciona llevo apenas 3 días y ya se ve el cambio. Puede que no dure el mes completo pero el paquete trae 6 repuestos así que no me apura mucho. Veo a mi gata más tranquila y eso me da mucha paz. Ya no se esconde y luce cómoda con la presencia de los nuevos. Si me llegó uno un poco derramado pero creo que es normal por el movimiento de paquetería. No vienen sellados ni nada solo enroscados. No paso a mayores. Vale la pena, hagan el gasto. También ayuda a que ya no peleen tanto.

Dangerous mine was smoking glad I was home do not buy

Did not work at all. Pls don’t buy

This product was designed for the US and Canada where the input voltage should be 120v, while our electricity in the UAE is 220v so when I plugged it in the diffuser started melting down, you will need a step-down voltage converter to be able to use it in this region.

This is an amazing product that really works. We have a female cat in our household. Recently, we had our family visit us. They brought with them 2 male cats and a Golden retriever. Prior to their visit, we purchased Comfort Zone Multi-Cat defuser. Three days prior to the visit, we plugged the two defusers in our living room and in the upstairs area. As soon as the new pets arrived, they acted very happily. The two cats were running around the entire house freely and did not display any fear or anxiety. They were rubbing themselves on the surfaces and were happy with us petting them. They were even asking for belly rubs. One of the cats is usually very skittish and runs away and hides a lot but when he arrived here, he was a totally different cat. Even his owner said, wow, he must really be reacting to the pheromones.Our female cat was a bit scared of the two new cats and a big dog, but after two full days of avoiding them, she finally relaxed. Now she plays with the two cats and hangs around the dog with no problems. We made sure that if it ever looked like the cats might get into a bit of a conflict, that we would separate them and give them some time to chill. We are very impressed with this product. I can imagine that it would be hard adding just one extra cat into the household. With this product, we were able to add two cats and a big dog without any problems. Thank you so much for such a miracle!
