Try this, it could change your life!
Thank you, Comfort Zone! Has changed the lives of my cat and me! It’s working very well on my formerly anxious and moody cat. She is more peaceful, happier, more playful, and no longer (occasionally) aggressive. To work well, replace diffuser about every 6 months. Order an extra bottle so you never run out! And it’s very important to follow the directions on placement. Follow directions on placement. IF you’ve tried Feliway and it didn’t work, try this; it’s a different pheromone. I’m so glad I didn’t let our experience with Feliway influence my decision to try Comfort Zone! It’s given us a much happier home.

These Definitely Work!!
These worked for us! We didn’t think they did until the cats started to fight again. First thing we do is check the diffusers and sure enough, they are out of juice! It’s very subtle to recognize but pay attention and you’ll see they work! One of our cats is a bully to the other and it’s much better now.

Peace Is Restored (perhaps only temporarily)
Update: about 3 months into this experiment, I have to say that I see an appreciable decrease in the effectiveness of this product, hence the drop to a 4-star rating. Growling and hissing at each other has returned, as has the pee-fest. I'll keep going for now but I think there's a fair chance we will abandon this idea if the efficacy continues to drop. We have three cats, one of which is male. All are indoor/outdoor. One of the females has never liked him and there are regular growling and hissing events. There's been a surge in feral cat and fox populations due to do-gooder neighbors who leave out food. This has resulted in cat pissing and fix poop wars around my house. The anxiety from outside appears to have ramped up the internal strife and the male started peeing everywhere. This is the second time we've had this type of pee-fest. On both occasions, we've deployed these diffusers with almost immediate success. I go overboard and we have six diffusers deployed, three on each floor. They work great and I'm happy to pay the cost as an alternative to locking the male cat outside, which causes him even more anxiety as he's slept in the house his whole life. Thanks to this product, I think we've overcome the problems for now.

Actually work!
So I have gotten these for years for my cats as we tend to move a lot and I do believe they work! of course they only work in the room or area where you place them, but I will find they gravitate towards that area, especially in the beginning of a move. I don’t notice any smell or noise and they seem safe. One tends to last me approximately 8 weeks I have noticed.

I've always used this product but this was the first time I tried the new dispenser
We have two cats who were abused by their breeder, and were never socialized. When I finally tried this product, it made a huge difference in them. They became more secure and relaxed. Recently, I noticed that the refill in the room where our male likes to be, was getting low and I made a mental note to order more. A few days later, my husband mentioned that he was acting a bit out of sorts and I realized I hadn't ordered it. I had been able to bypass the new diffusers but this time, that was all I could get. When I plugged it in, my husband wasn't home and when he came home, he mentioned that our male seemed to be feeling better. He didn't even know that I'd replaced the empty unit! That's what a difference it makes to our two cats. By the way, neither the new nor the old units have ever had any odor. I had heard bad things about the new diffusers and I kept checking on them but there was no oil leaking and they were actually cooler than the old type. The only thing I noticed was when I put in the refill , there was a film of oil all over the diffuser.. The same was true of the other unit but there was no oil on the floors or walls near either of them. I can't complain about that. I also read that the diffusers don't have to be replaced for twelve months so that brings the price of use down considerably. So thankfully, I can say that this product has helped us to socialize and soothe two abused kittens, and while they don't act exactly like other cats of their breed, they are two healthy twelve-year-old cats, with their own personalities and senses of humor. We enjoy them very much. Without this product, I don't think they'd be the way they are today.

Helps my cats significantly
I put these diffusers throughout my apartment when I brought home a second cat. Cat 1 is a bit territorial and jealous of my attention (she wants all the petting and chin scratches and belly rubs ALL THE TIME) and tends to try to push Cat 2 away from enjoying time in my lap, even swatting at her when she walks past sometimes. She’s also a dominance groomer, and while Cat 2 is honestly not a huge groomer, and seems to enjoy the attention a lot of the time, she has “no-go” areas that she usually won’t let Cat 1 touch (mainly her lower back). The diffusers really help them relax around each other. Cat 2 also has a disorder that makes her get twitchy and self-destructive if she gets stressed, so the diffusers also help a lot with keeping her on an even keel. A while back, I kept finding Cat 1 sitting next to the wall beside the window in my bedroom and couldn’t figure out why she would choose that spot to curl up - there was no particular visibility for keeping an eye on things, it wasn’t particularly cozy, there didn’t seem to be any of my things that she was sleeping on… then Cat 2 started sleeping there too! It took me a while to realize that they were sleeping right under the diffuser in my bedroom! 😂 In conclusion, if you have cats that are sometimes not the happiest of cohabitants, these infusers are great.

O melhor
Meu gato parou 100% com as marcações de território pós pouco tempo de uso. Considero muito melhor do que o da concorrência. Indico para quem está com esse problema.

Se derrama!
Creo que el producto funciono en mi gatito en el proceso de presentación a otra gatita, pero el producto llegó un poco derramado en su caja. Además, al parecer me enviaron un producto de devolución porque venia un sello de plástico encima de un sello ya abierto. El producto se derrama constantemente que lo tuve que poner encima de una caja para que no manchara. No lo use nisiquiera 2 semanas, fue un caos.
