Optimum Cat Calming Diffuser Refill (1 Pack, 30 Day Supply) – Cat Pheromone Diffuser Refill for Advanced Support to Reduce Stress, Spraying, Scratching, Fighting and Hiding

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.

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 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.

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!!

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.

I have been using this for quite a while now and have found it does calm my older, high strung cat. My problem is I have had several of the bottles or the diffusers leak. I find I now need to put a cloth or paper towel under the diffuser in case it is one that will leak. I see in the reviews that others have had the same issue and I agree that they are too expensive to leak all over the floor. If it continues I will not continue to purchase this item.

Has helped my cat so much. Does what it says. Great quality. No noise no scent. The device plug in does get a little warm but I’ve had no issues

I'm giving this 5 stars because I noticed a difference in my cats within a day of using them for the first time. The fighting stopped and the bullying stopped. The anxiety symptoms went away. There was a noticeable calm in the house and it was great. Fast forward a few months and it no longer works. We are right back to where we were before we started using it. I think cats develop an immunity to whatever kind you use. These may work again for us after we have taken a break from them. The thing is, they are crazy expensive and I have never seen a sale on them anywhere. It's a lot of money to spend, hoping that they will start working again. While they initially helped with fighting and bullying issues, they never did do anything about spraying problems. In all fairness, I haven't found a brand that has helped with that. As other reviewers have mentioned, these do leak oil. I haven't had oil on the floor or on the walls but the diffuser gets covered in it and then hair gets stuck to it. You have to wipe the diffusers off once or twice a week. Again, 5 stars because they truly worked better than any brand I have tried for the first 2 months. I wouldn't give 5 stars for longevity or for price. My cats have had a little break from Feliway Optimum so I would try them again, hoping for the initial result, if they ever go on sale.

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.
