Does this help with two male cats that atent neutered?
Answer by ChewyMar 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 ChewyJan 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 ChewyMay 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.

Is it okay to use the multicat refill in a diffuser that originally had the classic used in it?
Answer by ChewyDec 24, 2020
Feliway Classic and Feliway MulitCat refills and diffusers are interchangeable.

My littlest cat, Gracie, is very sweet, but very shy and not very sociable...she prefers hiding out in my closet behind a barricade of shoes she has built. I tried Feliway in an attempt to get her to come out and it worked...in just a few days, she started to come out every so often (altho still looking to keep her distance). We are now into month two of the experiment and she has actually joined the family, coming out for the better part of the day and interacting with people and other felines in the household. Definitely worth the money!

Amazing product!

This product is off the charts amazing! My fur baby suffers from separation anxiety and was getting sick a lot. When I took her to the Vet they recommended this and it has worked WONDERS! No more getting sick or stress eating.

If you try you will notice a big difference!

I honestly didnt think this would work. I received the first Feliway from my Vet and the 2nd and now this 3rd time I ordered from Chewy its alot cheaper through this company but anyway, my cats fight alot and the female who has been here longer than the male ( which by the way are spaded and neutered) she started urinating on the furniture and ruined our love seat. So started this and it worked. I ran out of this a week ago and she urinated on our bed and she was doing so good. So I ordered this right away and I plugged it in as soon as I got it out of the package! I recommend this product!

Still hopeful that peace will arrive

I started using this product 3 weeks ago. Seems like it didnt make it a full 4 weeks before evaporating but this is my second bottle. There is less confrontation in the house since I started using this stuff. Still fusses from time to time and the new boy hides from the others but the stalking killers are kinder now. Less bloodshed and more resting thank God. I think it helps judging by the evidence.

No thabk you

I have two cats. One is a lapcat the other not so much. I purchased the diffuser for a calming effect for my cat that isn’t a people fan. Unfortunately it had the opposite effect on my lapcat turning him to a wild boy, growling an hissing. I was beside myself. He may have rubbed in it an got it on his skin but I immediately unplugged it. If you have multiple cats I wouldn’t get it.

Feliway multi cat diffuser

When this was recommended to me by my veterinary practice staff I was skeptical . I was having a terrible time with one of my adult cats not accepting a new younger cat. The problem was so bad the adult cat developed a urinary infection which progressed to bladder stones requiring surgery bills were $1400 not to mention cat pee all over the house. This product literally saved me from re homing the kitten. They are not friends by any means but we have made immense progress unbelievable but it really works!

Great product

This product is amazing. I brought another cat into my household amd it was pretty tense and lots of jealousy but when I put the Feliway For Multiple cats diffusers in two different rooms The new cat calmed right down and the cat’s get along now. Great product. I used this product 5 years ago also to put two cats together. It an amazing product. I recommend it 1,000 %.

No effect on my cats

In a six week period that I have used this product, there has been no attitude behavior change with my two male, neutered cats. The aggression is still there and the spraying has not stopped. For my situation, this product has been ineffective.

Changed my life

My cats couldn't even stand the smell of each other. I couldn't have them in the same room for even a second without a huge brawl. I got Feliway and didn't notice much of a difference at first but now it has been 3 weeks and suddenly not only can they be in the same room but they play together! One of my cats still has some anger issues, but I can see a TREMENDOUS difference from before. I highly recommend!!

Cautious recommendation

Within 5 minutes of plugging in diffusers, my oldest cat came in with her nose in the air sniffing out the diffuser, so there is something there. After 2 months of the products being in 2 rooms only, we have noticed a serious decrease in physical fights between the 3 cats. Drive-by slapping is still common but the culprit is no longer seriously hurting other cats. He has even started playing with people again, something that hasn't happened in almost 2 years. He still beats up the dogs, though. Even the vet recommended trainer said "NO" when we called to ask for help. Box comes with diffuser and one bottle of pheromones only.
