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.

Worth the Money! Great for my xatay
I started using the Comfort Zone Cat Calming Diffuser Refills when I adopted my second cat. The adoption staff recommended them to help ease the transition and reduce stress between the cats, so I decided to give them a try. I noticed a significant difference after installing two diffusers around my house. Both cats seemed much more relaxed, and there was noticeably less tension and aggressive behavior between them. In fact, when I started seeing some of the old behaviors return, I realized my diffusers had run out. Once I replaced them, things improved again. The refills are very easy to install and require little maintenance. My only complaint is that they are a bit expensive, especially if you’re using multiple diffusers. However, because I’ve seen such a positive change in my cats’ behavior, I feel they’re worth the investment. Overall, I highly recommend these refills for multi-cat households or anyone introducing a new cat into the home.

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.

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.
