I Think This Actually Works!
I am extremely optimistic that this is working, and it is such a relief! At the end of September, 2025 my five-year-old cat had a tumor removed with her spleen and a kidney, additionally she spent 2 nights in the critical care unit of a pet hospital. A month later (end of October), after a full recovery from her life saving surgery, we took her to an oncologist where they did an ultrasound and x-ray to check for regrowth of the tumor, no signs of regrowth, they suggested another ultrasound in a month. We took her for another ultrasound at the end of November, no signs of regrowth. About three weeks later (mid-December) we took her to the vet again because she was licking and chewing her fur off on one side of her body. The vet did a thorough exam and gave her a flea treatment (even though she is 100% indoor but may have been bit at one of her vet appointments) and she was prescribed a short round of prednisolone to help with her inflamed and itchy skin in the area she was licking and chewing. Immediately following that last appointment, she started hiding from us and would not let us approach her. She went from being a very confident, happy, social kitty who followed us around and loved to be pet and snuggled to not wanting anything to do with us, like she didn't trust us. My immediate reaction was to take her back to the vet but I suspected her sudden change in behavior may be anxiety brought on by going to the vet so many times in a short period of time and was associating us coming close to her to getting picked up and going to the vet. I was concerned that taking her to the vet again after just going two weeks prior would potentially exacerbate her anxiety. I spoke with my vet and we started giving her gabapentin to help relax her. After a few days, she still was not acting like herself and would move away from us if we got too close, she acted very timid in general, but was not hiding any longer, it was a small improvement, but still concerning because it is not her normal behavior. The vet hospital where she stayed after surgery used pheromone diffusers in the critical care unit for cats, and although I was a little skeptical, I started to read reviews and saw enough positive reviews that made me decide to order one. That was Wednesday night, it arrived first thing Thursday and I immediately plugged it in. I don't know if it is a combination of time, the gabapentin, and the pheromones, but the noticeable difference in her after the first day was undeniable - she was more relaxed and would let us come close to her, sometimes we could even briefly pet her. I ordered just one diffuser and moved it to whatever room she was in. Because I could see an improvement, I ordered two more the next day (Friday) and they were delivered the same day - I immediately put them in each of the rooms she primarily spends most of her time. By Saturday, she started letting us pet her and give her snuggles, she still has moments where she does not want to be pet, but a huge difference. It is now Sunday, she is clearly more relaxed and she is letting us pet her give her lots of snuggles, and she is purring again. She is not 100% herself yet and we still approach her cautiously, but she is visibly much happier, relaxed, and friendlier. Based on her sudden improvement after using the diffusers, I am confident that these have worked, and it feels like a miracle. If you have a stressed or anxious cat, I highly recommend trying it. It may not have an immediate effect like it did for my sweet girl, but I would give it time, it is absolutely worth giving a try.

Yes it works, Optimum v. Happy Cats, range, etc.
Was recommended this product by a volunteer when adopting a feral kitten. I knew I’d have my work cut out for me and figured every little bit helped. So I got this ahead of time so it would be set when she came home. Fast forward a month. This little gem of a kitten is bopping around the home with my resident cat, pleased they were fast friends. And then out of the blue they began having some hissing squabbles turned physical fights over the course of a few days in the play area. This hadn’t happened since they first met. What the heck?? Then I realized the plug was empty. I put in the refill and by the afternoon and thereafter that behavior hasn’t surfaced again. I share this story because for this house, this product didn’t work miracles when I plugged it in. It still took a lot of patience and slow integration to bring these kitties together and for the kitten to feel confident in her new space. But it IS objectively a product that is noticed in its absence. The behavior was there when this plug was out, non-fighting kitties when in use 🙌 this is worth it. A couple things I wish I knew to begin with when deciding whether to jump on train feliway: 1.) the range of each plug extends up to 700 ft. I ended up ordering a second one and put them on opposite ends of the house. If your cat(s) have an isolated ‘hot button’ room or situation where they regularly have issues (like the master bedroom, at meal time in kitchen ie) you would likely be fine plugging the one in right in that area. If your kitties/cat has an overarching behavior/pattern you’re trying to manage, keep a close eye on that range to see how many you may actually need. 2.) After also trying Feliway’s ‘Happy Cats’ Multicat refill, this Optimum formula performed better here (optimum: 1-2x play fighting-turned-real fighting per month, whereas with the Happy Cats this was still happened 1-2x a week.) 3.) these plugs don’t last forever and will begin not putting product in the air. Instructions say these need to be replaced every 6 months. This is one of the few things I have on auto-ship to remind me to change the unit bc I will undoubtedly forget when I changed it last. 4.) I’ve had no issues with the plugs up to 6 months of use. They are super consistent at running out between 29-31 days.

Excelente produto para acabar com as “estranhezas” entre os gatos da casa. Já tinha usado o classic, mas este é bem superior.

愛猫の夜泣きがひど苦、寝不足気味。 藁にもすがる思いで、本品を購入。 効果不安はありましたが、夜泣きが落ち着いてきました。 他の猫やヒトへの影響はわからないですが、少なくとも我が家の猫には効果があったようです。

Me gustó el producto. Me gustaría que la luz verde que es bastante fuerte pudiera ser apagada, ya que ilumina el cuarto al dormir. El olor a mi no me parece notorio- de hecho el fabricante especifica que solo los gatos lo pueden percibir. Lo usé para ayudar a mi gato en la readaptación después de haber fallecido el perro que fue su compañero de vida- ya que el gato estaba presentando síntomas de ansiedad como comer de más y acicalarse más seguido y con mayor fuerza. El producto lleva ya tres semanas colocado en el outlet de luz y percibo al gato menos ansioso y sus síntomas han disminuído. Compraría otro para colocarlo en el otro extremo del departamento. Definitivamente sí lo recomiendo- aunque los repuestos/recambios son estúpidamente caros.
