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.

It worked at first
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.

A must have
This product definitely helped my cat. He was urinating outside his litter box. There is no smell and the product is easy to use just plug it in. Helped with his anxiety.

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.

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!

Leaks
It’s working really well at calming a stray I brought inside down but it’s leaking everywhere. There is no way this 30 day bottle is going to last that long. We’ve had it plugged in for one week and most of it is on the ground instead from leaking? Not really sure what is going on but it’s a mess. We’ve had these in the past and nothing like this ever happened.

Surprisingly, it does work!
I was skeptical and did not expect much. I was concerned it might be a placebo thing. I originally bought this about 2 years ago and didn't notice any change in my car at all. However, about a month ago my neighbor got a dog. (Bear in mind, I live in attached housing, with a suite next door, and we share a wall. The wall at the front of my kitchen is the back of the bedroom of the next door unit. My neighbor turned this bedroom into their new puppy's room.) Keep in mind also, as I said, I'd tried it before because my cat has mood swings that sometimes unexplained. But she began acting weirder and more violent than normal. She would attack me without warning (abnormal), and refuse to snuggle with me at night, which was our normal routine. She would bite, hiss, hide, and sulk and I wracked my brain for a reason to this sudden change, including changing my body products back to unscented and repeatedly checking the litter and her body for signs of illness. (She would barely let me let her even.) To no avail. The only thing I could think of was she could smell, hear, and sense the dog who was whining a lot during the day. Desperate, I decided to try again, else I was going to take her to the vet to check for a UTI or other invisible physical problems. The first day I noticed nothing. But each day, she became more and more friendly and within a week was seeking me out to sleep on my chest again. In fact, she has been slightly friendlier than she was BEFORE the dog. I am in shock and so grateful to have my friend back. This video was taken about a week after starting Feliway. I will say, she is still moody and that's just who she is, but she is back to her sweet self and significantly less angry.

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.
