FELIWAY Optimum Cat Calming Diffuser Refill (6 Pack, 180 Day Supply) – Cat Pheromone Diffuser Refill for Advanced Support to Reduce Stress, Spraying, Scratching, Fighting and Hiding

Excellent product that has helped tremendously with the introduction of a new cat into my household. After one of my cats passed away, her brother's behavior and his meow changed. I decided to bring another cat home and got Feliway to help with the transition. I experimented after about 6 months to see if they still needed the pheromone diffuser and saw right away how much things changed as the refills were not changed. They were more stressed, fought, and stayed away from each other. After refilling the diffusers, they were laying together, 1 grooming and the other allowing grooming, and getting along much better. I am thinking of trying another brand simply because Feliway is costly, however if I do not get the same results I will be coming right back to Feliway since it works so well! It is worth the price to keep the peace in the house!!

My cat had been dealing with a pretty serious over‑licking issue. She was removing patches of fur, and it was clearly stressing her out. After a vet visit, I was told it was likely a nervous behavior and was recommended to try the Feliway calming pheromone diffusers. I’m really glad I did. Once I started using this product, the constant licking stopped, and she’s been noticeably happier and more relaxed overall. It wasn’t an overnight change, but the improvement has been steady and obvious. The 6‑pack value bundle is great for keeping the diffusers running without interruption, and for us, it’s absolutely been worth it. Seeing her comfortable and calm again has made a huge difference. The diffusers don't make any noise and there is no scent. They work great and last about a month. The diffuser fits in a standard outlet and looks like a typical home fragrance type of diffuser.

I bought this with a new cat. After 3 hours, I noticed a calmer cat. Months later now, he has become the King of his Domain. I don’t know if it still has the same value, since he has adjusted to his environment. What I did notice: I moved a chair placed near a diffuser and found the back rails all oily. The diffuser emits an oily vapor into the air that short term may contribute to a desirable result. Long term, I don’t want to breath that or have it build up on my walls. This may be a useful tool, but it’s not the only tool in my toolbox.

This actually works. No more marking and a calmer cat! I no longer need to use them. She calmed and stayed calm. She was mistreated as a kitten, and this really helped her with her past trauma.

I have been very impressed with this product. I have been using it since February 2026 and my cat seems to be much less stressed than before we started with the diffuser. I plan to keep using it even though it is expensive.

Unfortunately the diffuser has not helped my two cats. Also, when I removed the diffuser from the socket it was very hot.

I bought this to help integrate my cats and to get them used to the room that I set aside for them. They still have free range of the house, but this room is THEIR room. It’s their hang out room where they can now be together. I bought the spray to begin with then added the infuser in two outlets. They did the job remarkably well and the cats ALL feel safe and comfy with each other in their room…so much so, that I no longer need the product.

This stuff does work wonders if you have it in enough areas that they spend time in. I have 5 cats 4 girls one boy and they fight the girls bully the boy and then the boy retaliates but i'm telling ya its like night and day difference in frequency and how violent they get when they have the diffusers vs when they dont last month i let it go a few days too long and i could instantly tell the difference they were going at it like crazy changed out the empty ones and i had my calm sweet babies again. I use 3 in my house and i could probably benefit from having one more I just cant bring myself to buy another plug in I'm already spending 50-60 a month for the refils. It for sure works though I tell everyone who has cat issues to give it a try≥..

I have a sensitive senior cat who doesn’t like change much as cats do, We plug in the Feliway pheromone and it calms him down. I love how you can purchase 6 rather than a single pack. Delivery was fast and condition was fantastic .

Luckily the item is in a plastic container. Maybe the supplier is trying to be green. Item within is ok.

全猫去勢避妊済みですが多頭飼いのためかときどきマーキングされます。各部屋にセットしてみましたが変化無し。何ならすぐ横にもマーキングされる始末でした。

Great product, the only one that helped my troubled cat integrate, after trying dozens of others. I recommend it.

Llego en el tiempo estipulado, aunque fue muy tardado para que se enviara, puede ser por las fechas. Es un excelente producto y mantiene a mis gatos tranquilos y evitando algunas conductas inapropiadas.
