We had used the Original Feliway for my cats previously but thought we would give this one a go as we have a multi cat household. Although this product was good, I found that the Original was better at keeping all of the cats calm, with Feliway Friends one of our cats continued to play up.
My kittens were fighting just that little too much. They are brothers who, most of the time are very affectionate to each other, but the fighting was getting more vicious. I tried Feliway Friends, and after a few days, there is a noticable improvement in temperarment between the boys. I have bought a refill. This product has been very helpful in arresting a breach of the piece at times! Would recommend if you are experiencing too much fighting.
