Great product that eliminated and over-licking issue with my cat
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.

Calms the cat !
I love this product because it eases my fur babies anxiety. I have used Feliway several times for different changes in my cats environment. From moving to changing up his routine to where he can no longer sleep in the bedroom in preparation for a new born to bringing the new born baby home. The diffuser makes no noise and provides enough oil content to last a month. It is small and discreet. You cannot smell it but your cat can and it helps your cat to feel safe and chill. Our kitty has been doing amazing with all the changes we’ve made recently and I owe it all to these!

Works great, doesn't last 30 days.
We recently adopted 2 cats from a shelter. One of the cats was having a hard time adjusting, she would barely come out from under the couch and was chewing on herself. Our vet recommended this to help her. It worked wonders! Not only did she come out of hiding but she let us pet her and plays with the other cat and us. My only complaint is that it doesn't not last 30 days. I have used it for 2 months and both months it ran dry after 20 days. At the price it is I would expect it to last the entire 30 days. We only notice it ran out early due to the fact that once the 20th day rolls around our anxious kitty starts to over groom and gets bald spots. Once we change it she stops, only for when day 20 rolls around, she again started over grooming. I even marked on my calendar when I changed it to see how many days exactly. If it wasn't for that we would give it 5 stars as it really does help. We are going to be trying some other alternatives due to the fact it is a little pricey, doesn't last 30 days and we hope after she's here longer she might not need it.

Takes some time but does works!
This calming diffuser has been super helpful for my 2 1/2 year old cat that has been dealing with anxiety. After purchasing 3 diffusers and plugging them in at spots she likes to rest in, I could see a change after a week’s time. My cat is becoming more calm and a lot less anxious to daily noises and changes which has been a blessing!!

Inspect each bottle
One of them came damaged. The felt adapter was snapped off making one un-useable. I would recommend removing the caps of each bottle when you get them so you don’t miss the return window. Had to throw one out.

Well worth the price!
Glad that I found this product, and it truly works for my cats. The younger one has toned it down with the older cat, and they now play well together! Thank you...

Worked super well for my anxious girl!
I know every cat is different…..but this was wonderful for mine! Bought this after noticing some irritation, withdrawal, and even slight aggression (towards my other two cats) from the world’s SWEETEST cat. We had just moved and she’s always done super well with moving, I just feel like she lost her “spark“ as she is always the most affectionate cat who loves sleeping in my bed and cuddling up on the couch. About a week after moving she stopped sleeping with me all night, spent most of the day in her cat tree, picked fights with her siblings (that she can’t win), was throwing up her food right after eating which is her classic anxiety “tell”. I know my cats, and I knew this wasn’t medical. I could tell she was having a hard time adjusting. I plugged this in and within 2 days she’s my girl again!!! Playful, ALL OVER ME, purring and trilling, not picking fights, much more active. Very very very happy. Also, I have no issue with my plug getting hot!

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 .

Bought this first from a local retailer as they had a money back guarantee. It worked so well for my newly adopted rescue kitty. She scratched furniture less, hid less, and just came out of her shell. When it ran out we noticed her being a little naughtier so bought this refill online. Seems to take the anxious edge off for our furbaby!

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.
