It does calm my cat down, the only thing I don't like it that it doesn't last long as a plug in and it is expensive. Thankfully, ebay has helped on the price

Turns out one of our cats is allergic to Feliway Optimum. He hasn't had issue with the other formulations in the past. Not soon after I plugged them in, he developed a runny nose. I didn't realize that maybe it was the Feliway until the night before another vet visit, where he'd gotten even worse after putting in a refill, so I unplugged it. They put him under for xrays and to drain his sinuses, and only found a bunch of gunk. He's been fine since the diffusers were unplugged. I figured I'd post a review since most of the comments were "no there's nothing in Feliway a cat would be allergic to".My other cat didn't seem bothered.

Doesn’t work. I have two sister cats who have been paired since birth that are now not getting along fighting. It didn’t do anything for their issues. Waste of money. Me with the calm voice does better at no charge. I’ll never buy feliway again.

Definitely see a difference in our scardy-cat boy. Last MUCH less than a month, wicks up/leaks if cap is off. Very expensive, especially because it lasts about half as long as advertised.
I have 3 cats that decided to all at once start fighting. I read reviews where the optimum worked better than the multi cat. The box said it would take 2 weeks to work. It took exactly the 2 weeks. Cats get along peacefully like they used to!!
This is a great product to help calm multiple cats in close quarters. It's especially helpful when it's time to call it a night.
This stuff works great ! Thought I would have to get RIP to take my cat to the Train Station !! Now I have the nicest Kitty you could ever want. Friendly and best of all uses her litter box.
Ive been looking everywhere for this at a reasonable price. This is the best price. My cat cant live without it. It helps her so much when its thundering and raining
Feliway was recommended by cat’s vet because she is an afraid and aggressive rescue, no idea her history but appears it was rough. The Feliway has made a tremendous difference, she is more relaxed and social, playful. With time, love, and the help of this product she is definitely more at ease and hopefully happy. It has been out of stock in stores and online the last 3 times I tried to buy refills. Hope that changes.
I am homing a new cat (8 years) and he was so nervous, i found this and put 2 in the bedroom (1 by the bedroom door and 1 in the living room. It calmed him down within an hour. I will probably have to use this forever for him. I let it run out (just forgot to check and was reminded quickly as he started getting nervous and I realized it was not working. Put them in and immediately he calmed down.
