I can't say that I saw any difference.
Maybe a bit calmer, but overall my cat has mood swings, so I couldn't tell if it affected him or not.
I wouldn't buy it again.

After three months of use, I did not see any change in behavior in my cats at all, none became calmer.

The veterinarian recommended it to me, due to the intense stress that our little cat is experiencing. Unfortunately, it did not help us at all.

I haven't seen a big difference, but I didn't expect the cats to turn into chickens, ho ho ho. Anyway, it is odorless and lasts quite a long time.

Amazing product! My cat had serious health problems due to stress, and my vet recommended feliway because if he continued to be so stressed, he would have the same problems to a greater extent. In the first few days of using it, I didn't see any difference, but now after using it daily for two weeks, I see a big difference in my cat's behavior. He is calmer and more relaxed than before. It worked very well for us, and I would highly recommend it for someone who has behavioral issues or stress problems in their cat, hoping it works for them too!
