Does this plug-in heat up? I remember an air diffuser plug in that did and it was a fire concern. I’d like to try this but I’m worried about it getting overly hot.
Answer by ChewyFeb 21, 2018
When the diffuser is plugged into a working outlet, the diffuser head will be warm to the touch. If the instructions are followed and the outlets are working correctly, this will not pose as a safety hazard.

Will my air purifier counter the diffuser?
Answer by ChewyNov 20, 2018
This can be used in a house (or a vet clinic) where there is an air conditioner or air purifier provided that it is plugged away from the unit, vents, cold air returns, or exhaust fan. Plugging it in too close will compromise the longevity of the pheromone.

I have been using the single cat Feliway plug-ins for a while now, but I need to switch to multi cat. Can I use the Multicat refills in my regular Feliway diffusers?
Answer by ChewyJun 22, 2018
The single and multi refills can be used interchangeably in Feliway diffusers.

Will this help cat fights?
Answer by ChewyOct 07, 2022
FELIWAY MultiCat helps reduce common signs of tension and conflict between cats at home such as fighting, chasing and blocking.

Promising Start with Feliway MultiCat Calming Diffuser

I used to be skeptical about the Feliway MultiCat 30 Day Starter Kit Calming Diffuser for Cats, thinking it was just a waste of money and a myth. However, after giving it a try, I'm pleasantly surprised. It's only been 3 days, but I've noticed a significant improvement in my cat Juicy's behavior towards the other cats. She seems less depressed and no longer howls for my attention. Instead, she's actively engaging with the other cats, playing and even showing more territorial behavior by climbing to the highest spots on the cat trees. She's also more proactive about interacting with other cats up there. This is a change from her previous reluctance to venture into those areas or take the initiative in securing her food and territory. Furthermore, Juicy has been displaying more affectionate behavior towards her humans. However, I'm still a bit skeptical about its effectiveness lasting for a full 30 days, as I can barely detect any scent from it even when I'm right next to it.

No Change

I got this hoping it would help my cat get along with my mom's cat I've had to watch for a few weeks now. I've had it plugged in for about a week and a half now, no change in either cat. One still growls and hisses at the other's door, and the other one tries to antagonize him under the door. Still have to keep them separated all the time or else they will try and attack each other.

Worked for our kitties

This stuff cured our furry friends hissing, stressing, pulling their own hair out, and screaming cat problem. Each of our cats now chilling around, sharing food dishes, litter boxes, even cat stands. I highly recommend this. The cost seemed reasonable for the chance. As I have tried a bunch of things. Glad we did as life in the house has become calm and peaceful.

Does nothing

Have two cats who don't get along that we have been reintroducing. This actually made it worse, with them getting in fights right in the area this was plugged in for a month, with one of them being so traumatized she sprays. I knew this wouldn't be a miracle worker, but I hoped it would at least reduce the tension somewhat

It has been a help!

I really like this! I ordered this after getting a kitten my other cat, I soon learned, quickly became jealous of! Alot of hissing in swatting in the beginning, but you could slowly see the two bonding after I began using this. In my opinion, this has been a help! I don't hear the hisses and see the swatting any more. The cats have began to bond and are friendly with other after a couple weeks!

Did Not Relieve Kitty Stress

One of my cats was acting out due to stress recently. The vet recommended Feliway Diffusers as a solution that could help. After purchasing two and plugging them in different locations in my 900 sq ft apartment, I noticed no difference in my kitty’s behavior. All in all, it may work for some cats but seemed to have no effect on mine. Plus side is - they seemed to last a while and had no noticeable odor.

works great!

This is the only one I have found to work in my home! I have multiple cats, I have not had in awhile and the behaviors show when I don’t. Trying to keep it all the time. The price is a little high to get one in every room.

I wouldn't be without this product

I have two cats, and I don't know if this helps or not, but I wouldn't be without it. They are NOT bonded, yet they seem to get along most of the time. I have used Feliway Multicat for years, and from the reviews, be sure to get the real Feliway--the one made in France, rather than the knock-off made in the US. I have never tried the knock-off, but the reviews made me want to get the real stuff.

chalked up to user error

Some of these people in this review section are DENSE. I’m seeing pictures of the feliway unit being installed -upside down- and then them complaining about it spilling everywhere? Anyone use their eyes to see the picture on the front of the box or read directions?? That’s crazyyyy to me. Anyways- I’ve used this introducing different cats 3 separate times since I live in a NYC apartment with subletters coming in and out, some with cats and some without. So far, so good. Even with the anxious cats it seems to calm them down more than anything else I’ve used. ****KEY is to place this item where the outlet is in a high-cat-traffic area with at least 5ft of space above the unit so the pheromone vapor can travel throughout the room. And if you believe 1 isn’t working try getting a second. Only betters your chances at some calm kitties

The packaging of Chewy has been consistently poor. This time one litter bag is busted. Why the wet food pouches and litters are in the same package? Please improve them.
