## Overview

FELIWAY Aroma Diffuser Optimum Cat delivers a patented, drug-free pheromone formula that reduces common feline stress behaviors like urine spraying, scratching, and fear. Each diffuser covers up to 700 sqft and provides continuous calming for 30 days, backed by over 25 years of veterinary research and trusted by millions of cat owners worldwide.

## Description

FELIWAY Optimum is a new, patented pheromone discovery, and is the best FELIWAY answer to help reduce the most common signs of stress in cats. It helps with more signs of stress, in more situations, and calms cats better than ever; it helps reduce scratching, urine spraying (peeing), tensions & conflicts among cats, general fears, and reactions to changes. This new discovery, backed by FFELIWAY's 25+ years of feline stress expertise, delivers advanced calming messages, helping your cats feel more comfortable at home than ever before. When surveyed, 93% of cat owners reported enhanced calming for their cats when using FELIWAY Optimum. FELIWAY Optimum's heated diffuser and refill provide calming pheromones continually for up to 30 days in a 700 square foot area. We recommend using an additional diffuser if the room is bigger than 700 square feet. We recommend plugging in the FELIWAY Optimum diffuser in the room where you cat spends the most time, or where conflict among your cats happen most frequently. Try not to plug the diffuser under items (e.g. shelves) or close to objects (e.g. behind curtain or doors) as this affects efficacy. We do not recommend plugging your diffuser in near your litterbox or in a hallway - while your cat may frequent these places, they likely do not spend as much time in these places as you'd think. If your litterbox is in the room where your cat spends the most time, you will want to plug your diffuser into that room. Use FELIWAY Optimum each month to create a constant calming environment. Check the diffuser and refills monthly; you'll want to replace the refill each month, and replace the diffuser head twice a year (every six months) to guarantee the best effect. Make sure to only use a FELIWAY Optimum diffuser with a FELIWAY Optimum Refill. The diffuser is not compatible with refills from other brands, and the FELIWAY Optimum vial should not be used with other diffusers. Never use a diffuser or refill of another brand with a FELIWAY product. Each FELIWAY Diffuser comes with a plug adapted to the local electric systems. Please do not use this diffuser in another country that has a different voltage or with an adapter: it may conduct serious security concerns. Make sure that your diffuser has the fitting plug for your country before plugging in.

Review: 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.
Review: Works… if you give it time. Helped my cat finally come back to my room. - I bought this because my cat randomly decided my sister’s room was the only safe place on earth. For a full month he barely left her bed — not to eat, not to explore, not to lay on my chest like he usually does. No major stressors, no house changes. He just withdrew. Two weeks with this diffuser plugged in and he’s slowly starting to drift back into my room again. Not magically fixed. Not instantly cured. But I can see the difference in how relaxed he is — he doesn’t bolt back to her room the second he hears a noise, and he actually falls asleep on my rug now. That hasn’t happened in weeks. You just need to be patient. This product helps, but it doesn’t flip a switch. ⸻ 🧪 How it works in real life (not in marketing language) This thing releases synthetic pheromones that mimic the “safe and calm” scent cats leave when they rub their cheeks on walls or furniture. Your cat basically interprets the space as familiar again, even if nothing changed visually. For my cat, the shift was gradual: • Week 1: He stopped hiding under my sister’s blanket every time someone walked by. Still preferred her room, but less jumpy. • Week 2: Started sleeping in my room for parts of the day. Followed me around the house for the first time in a month. • Now: Still splits his time, but he actually seeks me out again. That alone makes it worth it. If your cat is territorial, anxious, or has recently changed “favorite humans,” this helps smooth out the edges. ⸻ 🕰️ Timeline expectations (don’t expect overnight results) 24–48 hours: Basically nothing. Days 3–5: Slight decrease in clinginess and tension. 1–2 weeks: Real improvement — roaming more, relaxing in different rooms, less hiding. Full month: The diffuser is meant to build a stable baseline by then. If you’re impatient or expecting instant magic, you’ll think it doesn’t work. But if you treat it like a slow, steady recalibration? It actually delivers. ⸻ ✔️ Pros • Easy setup — plug in and forget about it • Genuine behavior changes over time (more confidence, less hiding) • Doesn’t smell or make noise • Helps rebuild routines after stress or environmental changes • Great for cats with “selective room loyalty” ⸻ ✖️ Cons • Takes patience — this isn’t a quick fix • Refills aren’t cheap • If your home layout is big, you may need more than one ⸻ 🔍 Pro Tips • Place it where your cat SHOULD be, not where they’re hiding. I put mine near my desk where he used to nap. • Don’t block it behind furniture. Airflow matters or you’ll basically waste the bottle. • Give it a full month. The packaging says 30 days because the effect builds. ⸻ 💬 Final Thoughts This didn’t turn my cat into a brand-new personality, but it nudged him back toward his normal behavior. After a month of him avoiding me and living in my sister’s room like a roommate who hates the lease agreement, this diffuser finally made things shift. If your cat is anxious, withdrawing, or suddenly glued to another person in the house, this is worth trying — just commit to the full 30 days and let the process play out.

### ⭐⭐⭐⭐ The Pascal's Wager of carpet peeing
*by L***Y on May 26, 2023*

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).
