The product did seem to calm my cat after a party at my house, but the pump spray part of bottle leaks when spraying the liquid.

I tried with my cat once in the garage but not sure that it helped calm her. Could not tell that she was any less stressed.

It seems to calm my skittish cats - maybe it calms me and the cats sense my lack of tension and react accordingly.  Either way, the cats seem to have less tension.

It seemed to work ok, then a week later , I found a few fleas on my cat again. Might be better as a preventative rather than a total solution.

My 1 male cat seemed to have an  occasional marking  problem but since I have used the spray I am noticing a good change in him more calm and less  problems. But you will have to go through the problem areas and respray with the Feliway probably once a week will keep your pet in check.

While I know people that swear by these, they just didn't work for our cat. Maybe he's defective, but he seems much more relaxed with catnip. The calming treats seemed to make him more agitated than before.

I wasn't sure if it would help but my anxious kitty seems calmer as of late! :)

We have a one year old female (spayed) cat that has separation anxiety. She cries and howls when her daddy leaves the house, then she goes and terrorizes any tissue, toilet paper, or paper towels that she can find in the house. She even learned to open the bathroom cabinets to get to the spare rolls of TP. After talking to our vet, she recommended the Feliway diffuser and said that although she had actually never seen a cat with separation anxiety, it worked for other behavioral issues. We plugged it in near the door that we usually exit from, and promptly forgot about it. In the next 4 to 5 weeks the crying and tearing things up had gotten better and we just figured it was a phase. At about week 5, I noticed the diffuser bottle was empty and unplugged it. Within a day, our kitty was back to acting crazy again. I bought the refill and plugged it back in, and she was back to being calm. She still cries occasionally, but she rarely tears up any paper. I was really surprised that it worked, but it does seem to actually calm our kitty down. Our other cat doesn't seem to notice it (she behaved fine before), and I can't smell it at all (despite my unusually heightened sense of smell). I will say that the diffuser starts to smell "warm" after the bottle goes empty, but otherwise it doesn't have an odor. The price on Amazon was much better than the vet or the local pet stores, but it is still a pricey item to have. I have also purchased the spray version of the Feliway product, but I don't think it works as well.

We purchased this product for our two cats to help them transition when we moved to our new house. It seemed to help tremendously. The product seemed to help calm them and make them not feel as stressed during the transitional period. We frequently use this product, especially when we go out of town.

I was skeptical but this works to calm down an anxious cat. My older female was stressed out when I adopted a younger male cat. I had tried most of the tips and tricks the cat savvy folks had offered without much progress, then I tried this product. Now my female is much calmer and not submissively urinating at sound of her new feline housemate. I still have to keep them separated but when they do accidentally meet, her reaction much less frantic and she doesn't hide in the closet for days after. She is chilled out now; that's the best way to describe it!

This stuff really seemed to help my kitties, especially when we were traveling and they were in a room with other people and animal smells in it. I plug it in first, while we are bringing in luggage, kitties etc, and it helps them settle in.  Seems to help at home if we are gone for long periods and someone is caring for them.  Did not make any appreciable difference in day-to-day activity though, so I only use it in those special times

I have used the Comfort Zone Multicat Diffuser kits for calming cats when I went or go on vacation. So, after my male cat missed his annual vet apt when he could not be caught I decided to purchase the spray. Both cats do go and sniff the crate when it is not in use. I hope in the future he will be less stressed getting into the create as I  keep it out for them to sniff and enter. I must admit the 2nd time I still have to coral him as he saw the crate and had not realized the spray was in use. His sister when with him - bless her heart - and there was very little sound from either. Especially, after when we went for an hour drive. Highly recommend it.

Item arrived quickly and in good shape. Other reviews mentioned leaks and/or broken pieces and I had no issues there. Only problem was the cat. He seemed to try to avoid it, moving into whatever room it wasn't in. He's old and little jumpy lately - I was hoping it would relax him, but didn't seem to make any difference. I'll try it again, just before the next vet visit.

ive only been using this product for less than a week, but i do notice my siamese is less anxious (he's afraid of his own shadow), but it hasn't really calmed my young cat down (less than a year), however, I do have to say the two cats hiss at each other less, and do seem to be tolerating each other better than before this product.

It seemed to make one cat more calm and mellow during a stressful transition in our home.  The other cat didn't seem affected one way or the other. My vet highly recommended it--if you have a nervous or anxious kitty and expect a move, or to be away for a day or two, or have some work being done at your place with loud noises/new people, I think it's worth a try.

I have been using this for a few days now to help a couple of kittens play nicer with each other and the older cats. One was feral born and the other was found on the freeway injured. Now that she's healed and starting to interact with the others there was quite a bit of hissing and growling going on for over a week between the two kittens.

I sprayed this on the places they play and sleep. The angry hissing and growling has stopped. However I really can't give credit to this spray since it usually only takes a few days to a week for cats to get used to each other anyways. They are able to smell this though since I have seen them take an interest in the areas I have sprayed this on.

They are now more interested in playing with their toys and each other than hissing and fighting. They do seem calmer, except when they do the high speed kitten zoomies through the house.

Not sure if I can recommend this product though. What I am seeing is more than likely just normal behavior and has nothing to do with having used this spray.

We currently have 2 of these diffusers in our apartment and this order was the refills for those. We have 4 cats who have always gotten along well and then out of the blue, 2 of them started fighting for no reason. I had heard good things about this product in terms of calming cats and decreasing fighting. I also heard that it can help with urine marking/spraying and furniture scratching. For us, it definitely calmed the cats and the fighting stopped. When the bulb ran empty though, they started fighting again a few days later. We ordered the refill pack and things are peaceful once again. For us, this product did not affect urine marking and only very minorly decreased urine marking. We are still very pleased with the product because our cats are happy again and all get along well again. That's worth it to me.
