Exact same ingredient as Feliway and works just as well for skittish or anxious cats.
I originally bought this for a very scared new kitten I'd gotten years ago. I tried every trick I'd learned to help a new kitten adjust to a new home and new owners but nothing was working. She was so scared, I couldn't get her to come out from under the bed. So, I decided to try this because a veterinarian recommended it to me. It is a synthetic pheromone that mimics the pheromone that new cat mothers release in order to keep their newborn kittens calm and safe while they nurse and sleep. I didn't have much faith in this, at first, but was willing to give it a try. I was told it could take up to 2 weeks and should be plugged in the room the cat is in most often. It doesn't affect humans and we can't smell it. I continued to lay on the floor and talk to her as she hid under my bed, made eye contact with her, would reach my hand out to her and even sing to her. Nothing. By day 4 with Comfort Zone plugged in two different outlets in my bedroom, I heard her start to purr as I talked to her. Then, I put my hand out and she slowly sniffed it. Eventually, I had her rubbing her face against my hand, which means she's marking me with her scent; an honor coming from a cat. Little by little, I noticed a bunch of changes from her coming out from under the bed during the night time to eat by the window, rather than eating under the bed, walking around the room in curiosity about what different things there were to smell and climb and then came the biggest change which I began to fear may never happen: She jumped up on my bed and slept at my feet. After that, I knew that with time she'd be the affectionate kitty I knew she wanted to be. The poor thing was just so overtaken by fear and anxiety that she wasn't able to do anything about it until she felt safe enough. That was my first experience with this amazing product. I've used it for many cats for a variety of different issues, most recently being, my 4 year old Burmilla cat bullying my 2 year old Burmese cat. I've plugged two in for them. One is in my bedroom, where my younger cat hides from the bully cat and the other is plugged into the outlet near the cat tree downstairs, where my lovely but bully kitty tends to hangout. These have been plugged in for a week and a half now and there have been a lot less fights, my younger cat has gained some confidence and leaves my bedroom during the day for small periods of time, here and there. My older cat isn't stalking the younger one as much and seems to be less pent up with urges to attack something or someone. It's hard to know how much is time, work on the owner's part and how much is from this pheromone but given the number of times I've used it and there has been some change, though neither drastic nor complete personality change, it's enough behavioral change to give me belief that it definitely plays a beneficial role in most cats' progress.

Cat Friendship Secret Weapon
We just adopted a second cat. Thanks in part to these diffusers, both cats were playing together within the first 24 hours and started snuggling/grooming each other within the first 72 hours! This is obviously not the norm for everyone, and I also did a lot of research on cat introductions and carefully matched their personalities to each other, but I’m fully convinced the diffuser is working. In fact, on multiple occasions, I’ve seen either cat walk over to a plugged in diffuser and start huffing it after they start to get a little stressed or overwhelmed.

It might have done the trick!
Can't say for sure that this diffuser was responsible (correlation doesn't equal causation, etc) but I will say that within the time I've had this, I've seen a massive reduction in problem behaviors and much more trust and relaxation between my 2 cats. My main annoyance was the leakiness of the bulbs unless you screw them in just right. Doesn't get nearly as hot as the Feliway diffuser though, which I stopped using out of fear of it being a fire hazard. This thing is plugged in all day with no issues.

Kind of messy product. Can’t say if it works for by cat. He’s been a health mess.
I’ve used both Feliway and Comfort Zone. I’m honestly not sure if either works all that well for my particular cat. Up until recently he had a pretty chronic urinary tract issue I wasn’t quite aware of the extent of that led to spraying and urinating on the carpet. I got him on a healthier low phosphorus and magnesium diet (seriously go to your vet and figure out a diet to get your male cat out of a UTI, crystal cycle that might be present). A better specialized diet has gone a long way in the last month for me. There’s a lot of good info on cat health/nutrition diets available these days that might honestly be a good complement or alternative to a product like this. This product is cheaper (significantly so than Feliway), so if moneys is an issue it might be worth sticking to this. My cats not really a good test case for it’s fidelity in my last two years of switching on and off of the two products. I will say that the design of the Comfort Zone plug in is far more stable on the wall than Feliways. The actual vials of fluid of Comfort Zone tend to leak a tad and get a tad sticky/slimy to the touch in some circumstances which probably means the covers are probably not fully sealed. The actual process of how the comfort zone product works or the formula of the fluid tends to kick up wet/sticky steam that can coat the walls and stick to the plug-in and bottle, so removal is a tad messy. I’d not noticed either issues with the Feliway brand. Not a huge deal. It just comes with a higher degree of needing to clean the product and the area around the plug-in a tad more. This product you are trading some degree of quality for cost savings at least in terms of how the tech part of the product works and how it’s packaged. You’ll need to look to other reviews from people who didn’t just in a Hail Mary continue to buy the product just in case it helped a smidge over the last two years.

Definitely worth it to help cats calm down.
These two were instant enemies. Our older ten yr old girl was having NONE of the new kittens shenanigans. We did the introduction by the books, seperate spaces and then finally we let the kitten roam free, and when we did that, my older cat really had a tough time. She was quite literally like a rock. She tensed her body up so much, she hissed so hard at him, that she gave herself an asthma attack. I was in tears because I thought we'd have to take the kitten back. I ordered this and prayed. I'm not even religious really, but hunny, I prayed these cats would get along. Now, at first it wasn't working, it was getting dangerously hot, I thought the other reviews were right. THEN I noticed it wasn't a clip in, it's a screw in bottle, it wasn't in all the way which made it get hot! I also snipped the bottom and top a bit to help absorption. I have been checking it every day though, and if you get one I suggest keeping an eye because I think with any air wick type thing, 1/100 is going to be a dud/fire hazard. Even the air wick reviews have these same issues. So first off, make sure the bottle is screwed in all the way, snip the bottom if you don't think it's wet enough (if your hand doesn't get SOMETHING on it when you touch the soft brown thing at the top, it's not absorbing correctly!) Also, I think those of you complaining about it not working probably have a larger space and you need more than one. They clearly suggest one for every room, I noticed a HUGE difference just by adding a second one. So, don't give up on a product just because it doesn't work as fast as YOU want it to. Especially if you're introducing cats like me, it takes time, much more than a month most likely. And all air wick thingys only last a month, so I'm not sure why anyone is upset about it lasting a month 😂 Guess no one reads before they buy stuff. 🤷♀️ So I hope this helps some of you out there deciding on this. Because I'm getting one for every room! I've also mixed both brands, the feliway and this one. If you love your cats like I do, it ain't no thang.

Burning plastic smell after 30 minutes
I bought these and had them overnight shipped to me because I just moved into a place that already has a dog and cat present. My cat has been very territorial and anxious basically in fight or flight mode since she’s never been around other animals before this. I got this product this morning and plugged it in right away. I went about my morning and about 20 minutes later I started smelling a weird smell but just thought it was the pheromone scent I was possibly smelling. Another 10 minutes went by and the smell was getting overwhelming so I checked both units and they were burning hot to the touch and emitting a very strong burning plastic smell, the plastic on top was starting to get soft and pliable which means it was starting to melt. If I had let these go without checking them I would have returned to a burned down house. If I could give 0 starts I would.

Magical!
This stuff is magical! I just moved to a new apartment and my cat did not appreciate it. She would hide during the day and as soon as I would lay down to sleep, she would wander the apartment and meow constantly. For hours & hours all night long. I’m a lite sleeper so I didn’t get much rest at all. I expected her to need some time to adjust but I had no idea how long. Days? Weeks? Months? A friend told me about this stuff and I was desperate to try anything. When it arrived, I plugged it in immediately. That night she was so much better! She still got up, wandered & meowed but not nearly as much. And by night 2 with it in use, she was completely fine. She may have wandered but she was quiet and I was able to sleep. From what I understand in researching the product, it doesn’t work on all cats and it can take weeks to work. But For my cat, it worked great and super fast!

They helped
We just got back from our first trip leaving our cat alone in five years. I believe that these helped her anxiety and separation. I can not guarantee these but I believe that the helped.

75% de eficiência
Usei o produto na adaptação do meu 4° gato. Posso dizer que vi diferença no comportamento de dois, apenas um que demorou mais para aceitar o novinho. 75% de eficiência é um pouco triste pelo valor.
