Results may vary depending on the presence of other pets and on other environmental factors**When used as directed***Based on a survey of 200 veterinarians Review: 5 star - Not entirely sure if it works. I bought it for my anxious cat, who has health issues to calm her. Don't really much difference. I do take it out from time to time. I have noticed 1 thing. She sleeps next to my head on the bed, near it. Every night. People complain that it leaks. It doesn't if you have it upright. Just make sure its not like in a power strip or sideways outlet. Her health has improved since I got this. So the review is whether this product works. Yes. But mile may vary. Could be your cat isnt sensitive to pheromones. Last longer then 30 days, and if you are smart, you can take the remainder liquid, put it in another bottle and make ot stretch longer. Be sure to not leave it plugged in empty. Review: Excellent Product — Worth Every Penny! - Absolutely love Feliway! With six cats in our household, I’ve been using Feliway Classic for several years and have consistently noticed a positive difference in their behavior. In fact, I can usually tell when the diffusers need refilling because their activity levels and behavior noticeably change. It doesn’t sedate them, but it definitely seems to help create a calmer, more relaxed environment. I recently switched to the newer Feliway Optimum formula, and I’m already noticing encouraging improvements within the first 24 hours! I’m excited to see how the results compare with the Classic version over time. These products are certainly not inexpensive, especially when using multiple diffusers throughout the house, but the benefits we’ve experienced make them well worth the investment. Fast shipping is another plus. As a longtime Feliway customer and owner of six cats, I highly recommend giving this product a try! ## Features - HELPS REDUCE SIGNS OF STRESS USING A PATENTED PHEROMONE: FELIWAY Optimum is an advanced cat pheromone diffuser that helps reduce signs of stress in cats and helps ease tension between cats.* - HELPS CATS FEEL CALM IN EVERYDAY SITUATIONS: FELIWAY Optimum is a cat calming diffuser that helps reduce stress‑related behaviors like urine spraying, scratching, hiding, and fearful reactions to change.

I cannot tell if it's working or not** A: Mine stays on all the time. If it's not warm to the touch and the light is off it's probably not working. **Q: I adopted a feral kitten a year ago and she hates loud noises so she hides during the day will this help?** A: I have the same issue. At first, Feliway worked to reduce stress in my rescue cat who hides from me most of the time; no loud noises and I live alone. However I highly recommend using the Feliway diffuser together with the Royal Canin Calme food. You can purchase that through your veterinarian. **Q: I just received mine and it’s making a smell like a hot glue gun. It’s very strong. Is this supposed to happen or is this on defective?** A: Mine started smelling the same and I looked at the inside and the plastic interior had melted. Super scary. **Q: Does the diffuser still work if the green light isn’t lit but is warm to touch?** A: I don't know. I don't know if there's a way to turn off the green light. I thought of putting tape over it, but was worried it would get too hot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5 star *by D***N on October 12, 2026* Not entirely sure if it works.

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). ## Frequently Bought Together - FELIWAY® Optimum 30 Day Cat Calming Plug In Pheromone Diffuser Starter Kit, 48ml - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming - FELIWAY® Optimum 30 Day Cat Calming Refill for Pheromone Diffuser, 48ml - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming - FELIWAY® Classic Cat Calming Spray, 60ml - Comforts Cats at Home and On the Go and Helps to Calm During Travel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/336328293-optimum-cat-calming-pheromone-diffuser-kit](https://www.desertcart.fi/products/336328293-optimum-cat-calming-pheromone-diffuser-kit) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-10-30*
