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.

Good changes

In three days there was a change in my house. My oldest cat quit being aggressive towards the other two girls. The other two girls were nemeses from another house and have started tolerating each other better. They have also started accepting the new male cat as long as he stays out of their food dishes. The best change is we can all be in the living room without any tension. They still watch each in a relaxed way but I haven't had any major fights since I plugged the calming diffuser in. YAY! That's a win in my book.

Very Helpful

I have used Feliway for years with many cats. I have always found it to be calming for cats who are a bit nervous. It's not a personality changer, and I have never looked for dramatic changes. However, it's always been good at taking the edge off of anxiety. I'm using multicat for a single-cat household now and find it just as effective as the original version.

Doesn't seem to work on my little boy

Admittedly we haven't been using this for the full 30 days but so far, it does not seem to be working for my orange tabby that wants to bully my foster kittens. He's still hissing and swatting at them. We put these two plug ins in the rooms where they hang out the most and still no real change noticeable. It's disappointing - I really hoped it would work.

didn’t seem effective

I used two in one room to try and help my cats get along. I used them until they ran out and never noticed any calming effect, they still seem stressed and fight. We have plenty of resources for both so I was hoping this would help. I did see the vet had this diffuser in their office so maybe it works for other cats

Solved multi-cat behavioral problems

With a six cat household, problems began when the senior and top cat for many years passed away. Two cats wanted the new position so there was fighting and urinating in inappropriate places. The cat pheromones in the diffuser did its magic and the cats behavior returned to normal the very first day I plugged it in.

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.

Didn't Work

We hav two additional cats in our home. We've tried the plug in to help out #1 cat to be less aggressive. (18 lb neutered male). It's been 2.5 weeks. Didn't help in this case. Plug in was placed in living room where he mostly hangs out. It was worth a try

Keep bullying at bay

My vet recommended this, as my oldest female continues to reject our female kitten (Now 1-year-old). I was hoping to avoid medication and this is just the thing that has helped. It hasn't stopped it completely, but it has helped. Plus, everybody seems a little "happier."

Works for me but

I’ve had this solution for about 2 weeks so far and I really love it BUT it leaks a lot. I’ve tried everything to not get it to leak but nothing seems to help. Will probably continue to buy refills because it seems to work so well for my cats.
