Feliway classic, multicat, and optimum all say feline pheromone at 2% in the ingredient list; why is the optimum so much more expensive and I have to buy new difusers if they all have the same amount of feline pheromone in them?

Does this help with two male cats that atent neutered?

Answer by Chewy • Mar 29, 2018
We'd recommend using the MultiCat system in the room where the cats frequent the most, it should help calm and reduce tensions.

I first saw these in my Vets office. Was skeptical, but put several around the house. (I do Cat Rescue, and have a mini cat hotel in progress) The results were noticed within a week. With so many diffusers a large economy refill bottle would be nice :)

Answer by Chewy • Jan 19, 2018
At this time, this refill is only available in a 48 milliliters bottle.

Does it matter if the outlet is higher up on the wall or does it have to be closer to the floor?

Answer by Chewy • May 15, 2018
Plug diffuser unit into the room where the cat spends the most time. Avoid plugging in the diffuser under shelves, behind doors, behind curtains, behind furniture. Doing this will impair diffusion.

Helped chill out aggressive cat

My boy cat has the tendency to be aggressive with his sisters even though they've been together since they were born, but I digress. The Feliway Multicat was recommended

My boy cat has the tendency to be aggressive with his sisters even though they've been together since they were born, but I digress. The Feliway Multicat was recommended by the Chewy vet chat and it was a great recommendation! He's definitely calmed down and there's a big reduction in his aggression. I'm on my second refill so I am hopeful it continues to work.

I think it works

It was suggested to me by one of your vets that you can talk to on the phone. I have two neutered male cats who had started wailing by my apartment door at 2 am

It was suggested to me by one of your vets that you can talk to on the phone. I have two neutered male cats who had started wailing by my apartment door at 2 am. I didn't think my neighbors would like that so I called to get advice. This diffuser was suggested so I tried it. I'm on the 2nd one now and it seems to be working. Thank you

Wasted my money very unhappy with this product

Same review as the starter kit - same order same product.. I spent like $60 on this with the refill bc our cat Cream Puff has been really anxious and peeing all

Same review as the starter kit - same order same product.. I spent like $60 on this with the refill bc our cat Cream Puff has been really anxious and peeing all over our house. I had hoped this would help her calm down and knock off the habit bit it didnt work. We are now considering what other options we have so I am really disappointed in this product and wish I didnt waste so much money. Btw I also know it doesnt work bc I have 4 cats and after plugging this in my boy cats started to fight when they never did that before. So I dont know what the point of this even is.

We received our order today and put a new feliway bottle on the part that gets plugged in. We noticed a strong burning smell after a while so I took it off. I set the oil bottle on a table and noticed it was leaking all over the table. We have thrown that oil bottle away but bought a multi pack and are concerned about the other bottles leaking as well.

While this product seemed to work for our cats to stop fighting, one of the diffusers started smelling like electrical burning. I have had two in the house. at 30 days, the light never signified that it was time to change the diffuser refill. I went ahead and changed it anyway. At this time, I noticed the one was oily like the oil had leaked. I cleaned it up, changed the diffuser and plugged it back in. Shortly there after, the room began to smell like electrical burning. After researching, I have unplugged the diffuser and I am super disappointed. I only used it the one month. We are leaving town and I'm also afraid to leave the other one plugged in should the same thing happen with that one.

Cats seem to be calmer. Quieter nights

Annie's gang is a large group of cats. They have been recently traumatized by a stranger coming into the home and scaring them. Since I put the Feliway diffuser

Annie's gang is a large group of cats. They have been recently traumatized by a stranger coming into the home and scaring them. Since I put the Feliway diffuser in they seem to be calmer. Quiet nights for the cats mean s that better sleep for me.

THEY WORK!!!!

I have 4 diffusers throughout my house! Because I have 6 cats (all rescued) and 1 of my girls, Lucy, is on Prozac (it's a Tordietude thing) I can ALWAYS tell when

I have 4 diffusers throughout my house! Because I have 6 cats (all rescued) and 1 of my girls, Lucy, is on Prozac (it's a Tordietude thing) I can ALWAYS tell when it's time to change the refills... because everyone, especially Lucy, starts to get a little testy! One time I had totally forgotten FOR A WEEK and my house was total chaos!!!! After I realized what was happening and changed the refills... it took about a day to get everyone back to normal... I'll NEVER do that again!

Had been ok till last few months. BEWARE Of change no longer works!

Our tabbies had night time fights. This product resolved this problem until recently. Now the smell is awful, leaks and made the cats anxious during the day when

Our tabbies had night time fights. This product resolved this problem until recently. Now the smell is awful, leaks and made the cats anxious during the day when it’s being run(never occurred for the 2 years we’ve been using this successfully). I’ve tried a few of the complete kits and replacement bottles. All the same just awful. Will NEVER use this again. I’m not sure what Chewy can do about this (refund) but I’ll be contacting Feliway.

Not sure if they actually work

I had been using for years when I am away for extended periods of time, but now trying while I am home and feel my older cat just isn’t taking to calming down/anxiety

I had been using for years when I am away for extended periods of time, but now trying while I am home and feel my older cat just isn’t taking to calming down/anxiety around dinner time. Who knows. He is part Bengal, so it’s probably just me or him. ;-)

Helps ease tension

My cats mostly get along, but the two year old boy sometimes gets to be a bit much for my senior girl, causing obvious stress in their relationship. I can tell when

My cats mostly get along, but the two year old boy sometimes gets to be a bit much for my senior girl, causing obvious stress in their relationship. I can tell when the feliway runs out because there seems to be more tension between the two of them. With feliway, there’s peace in the house and all three cats are happy together.
