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.

Subject: Noticeably Calmer & More Confident Rescue Cat 🐾
I’ve been using the FELIWAY Optimum diffuser for my rescue cat, and I can honestly say I’ve seen a noticeable difference in her behavior. When I first brought her home, she was very cautious and kept her distance. After plugging this in, within a short period of time she became much more relaxed, calm, and approachable. Now she spends more time out in the open, lounges comfortably, and even seeks out attention more often. What I really like about this product is that it’s drug-free and easy to use—just plug it in and let it do its job. It continuously releases calming pheromones for up to 30 days, helping reduce common stress behaviors like hiding or tension . 👍 Pros: • Helped my rescue cat feel safe and secure • Noticeably reduced anxious and hiding behavior • Plug-and-play, no effort required • Great for new environments or transitions 👎 Cons: • Works best when used consistently (you’ll need refills) Overall, I highly recommend this for anyone with a new rescue, anxious cat, or multi-cat household. It’s been a simple but effective way to create a calmer home environment, and it’s made bonding with my cat so much easier. 🐱💙

The Pascal's Wager of carpet peeing
Look, I'm not the type to leave a positive review on something that I can't prove is working, but in this case, it's a likely enough candidate to give credit where credit is (possibly) due. Our beloved eldest is perhaps the most anxious cat in existence. Before he came to live with us, he spent his youngest years being terrorized by an older, aggressive cat who would often ambush him in the litter box. He developed a lifelong fear of using it to pee (weirdly not for #2), and would try to pee literally anywhere else, be it on rugs, clothes that had fallen out of laundry baskets, hardwood, tile, cement, you name it. Any surface other than his actual box. Here's a truncated list of things we have tried to calm his anxiety/keep up with his peeing: - Different types of litters - Different styles of litter boxes - Different locations for the litter box - Litter attractants - Diet changes - Deterrent in his favorite floor spots - Enzymatic cleaners to try to remove any lingering scent - Extensive veterinary testing - Consults with behaviorists - Rewarding him when he uses the litter box (recommended by behaviorist) - Retraining in a large kennel with a litter box (recommended by behaviorist) - Calming collars - Other Feliway products - Prozac (prescribed by the vet) - Gabapentin (prescribed by the vet) Nothing worked, other than an elaborate and not entirely foolproof routine of taking him to the box personally and guarding him while he was in there. We had to do this multiple times a day, and he would still sometimes try to sneak off to do his business elsewhere. So, when we moved to a one-bedroom apartment with a lot of carpet, we were prepared to immediately lose our security deposit to his anxious peeing. We were convinced the move alone would leave him emotionally shaken to his core. We armed ourselves with some of the most highly-recommended enzyme cleaners (Rocco & Roxie), and were looking into expensive waterproof covers to put on approximately 600 sq ft worth of carpet, and then cover those with washable rugs. We were ready for battle. I called our vet to ask for a light sedative for both him and his younger brother, to make the moving day less stressful, and the tech suggested that we also get these specific Feliway diffusers. Although we hadn't had any luck with Feliway in the past, we were throwing absolutely everything we could at this, so we figured the worst they could was not work. Cut to moving day. We put both our groggy cats into the new bathroom with their litter box while the movers stomp around bringing in boxes and furniture. The second they're gone, we plug in the diffusers, let them run for an hour, and then cautiously let the cats out. Both of them are low to the ground, skittering from one room to the next in utter confusion. Eventually Anxious Cat finds a window to plop his butt in and doesn't move until dinner, but we spend the entire time watching him while we unpack, ready to jump up if he seems like he's scoping out new pee spots. By the end of the day, he hasn't used the litter box yet, and we're starting to wonder if maybe we should close him up with it in the bathroom for the night. At least there's no carpet in there. And then we realize ... we've lost sight of him. We bolt up and start canvasing the apartment, only to hear the digging of little paws in litter. Slowly, we creep to the bathroom door and peer in just in time to see him hop out of the box, giving us both a look of mild confusion as he sprints off to the window. But we weren't sure what he did. If he pooped, well, that's nothing out of the ordinary, and there was some in the box, so it could've been him or his brother. We decide to lock them in the bathroom for the night, but eventually succumbed to their piteous sobbing and let them out. Come morning, there's still no pee, but Anxious Cat is a champion at holding it until he finds the perfect spot to unleash. But finally, come afternoon, we actually manage to catch him in the act of peeing IN THE LITTER BOX. It's a monumentous occasion, and we shower him in catnip, treats and lots of play. He's delighted, and no longer slinking around with his belly to the floor. He's acting like a normal cat, cautious of his new space, but enjoying the comfort of his familiar beds and toys. It's now been two weeks, and he has done all of his business in the box, and NOWHERE ELSE in the apartment. We haven't even taken the plastic off of all of our enzyme cleaners! His anxiety is way down in general, and so is ours. We can let him out of our sight for hours at a time without worrying that soon we'll smell cat pee. This has been life-changing for him, and for us. I've never seen my little old man happier than he is now. And maybe it was just the change of scenery, the smaller space, not being able to smell the neighborhood cats who used to hang around our old house. Or maybe it's these Feliway diffusers. I honestly have no idea. But, I'm going to keep believing in their possibly magical power and keep buying the refills if that's what it takes to keep him happy, and keep our security deposit. So, why four stars instead of five, if this is (maybe) such a miracle product that has so improved the quality of life of both our cat and his human parents? Because it had ZERO effect on our younger cat. Usually, he's incredibly easygoing and adapts well to change. We weren't worried about him at all when planning the move, we figured he'd be as chill as he always is. Instead, he's been terrified and although he has no issues with using the litter box, he's spent most of these last two weeks hiding, jumping at every sound and refusing to play like he usually does. It's extremely unlike him, and it's pretty clear that the Feliway is doing nothing to help him. Which makes me think this product is very hit or miss, if it's doing anything at all. But rather than risk eternal damnation, I choose to believe in the power of Feliway, at least when it comes to our Anxious Cat (pictured above, with the carpet he has yet to ruin).

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.
