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: A solution to a problem that went above what I had expected! - I have three cats that got along for the most part I wouldn't say they were best buddies. There was some chasing on occasion, no one laid together but for the most part everyone did their own thing and tolerated one another. I purchased FELIWAY with the hopes to calm the chasing down when my one got diagnosed with urine crystals. After about a week I noticed the chasing stopped, she eventually healed up and within the month the FELIWAY ran out. My son came up to me one day and told me the cats started waking him up again at night. I was not aware that it had stopped. I then kept a closer eye on things and noticed the chasing during the day started again. So I ordered more just to see if it was a fluke or if indeed FEELIWAY made that much of a difference. We now are on month three of the plug-ins and the chasing has stopped, they don't wake my son up at night anymore, all three cats now lay together in cuddle puddles and my one girl who refused to go down the hallway into the bedrooms now sleeps with us at night. I can't recommend this stuff more. I have three plug ins for my 1600sqft house. Its an expense to upkeep but its been well worth it. Review: 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. ## 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 feel like my cat is getting used to the Classic and it doesn’t calm him as much as it used to.** A: I have used the multi- cat on & off for years with excellent results, but I wanted to give the optimum. Not sure if it's necessarily better (both are equally effective for us) but it definitely works faster. For your situation, switching to a different formula is worth a shot. **Q: Can the same diffuser i have for the multi cat be used for this?** A: The instructions actually say to not use another brands diffuser for the refills, and not to use another brands refills in the diffuser. It does not specifically say to not use another one of their own diffusers. I will say I used my old multi cat diffuser and it was fine and worked well. **Q: Can this be plugged in 220v or just 110v?** A: I believe it would only be safe to use in 110 volt. **Q: Can you use this in a dog friendly home with two cats?** A: You may want to contact Feliway directly for the best answer. That said, the cat pheromones shouldn't effect your dog. If your dog is a chewer I recommend plugging in somewhere the dog can't reach it since it's ball shaped (or train the dog that it's strictly off limits). ## Customer Reviews ### ⭐⭐⭐⭐⭐ A solution to a problem that went above what I had expected! *by S***P on August 18, 2026* I have three cats that got along for the most part I wouldn't say they were best buddies.

Do it. It's the "cheapest" affordable way If you love your cat enough to run them to the vet when he's not peeing and not doing well and every vet, person and Google says he could die (because that is a real possibility either from urinary blockage or not eating) You'll love them enough to get these. I can't afford it all, the royal cabin uti food, gabapentin, forti flora, and Feliway. My cat has FIV. He gets stressed when the litter box isn't clean, when it stinks, when the food bowl gets low or empty. He's unhappy when the water gets low, if there's not enough or no scratchers at all. No playtime at all, no cuddles, no attention, only one litter box, loud noises, no routines, stinky things, bad AND good because not all scented things are good for us, especially for animals. Now, I struggle with depression and a slewwwwe of things. I have anxiety and my esa boy has anxiety. Providing them the bare necessities is soo important. More than one scratcher, he loves cardboard and twine. Multiple high points must be provided for a sense of safety and security. Don't chase them or stomp or yell. Keep laundry, trash and kitchen not too stinky. Food and water daily. But what I was struggling at that he found stresseful was. Not giving him the bare minimum of attention 15 minutes. Which caused him to lash out at other kitty in aggression and made me yell... Cleaning the litter box was really hard. I switched to pine with stainless steel litter box and pee pads. Keeping up with stinky chores Forget to fill the food on time Or forget to rinse the water bowl Those are things I've improved on for his sake and mine (medication therapy ect) I've also switched to pine with stainless steel litter box and pee pads. Got him wet food to increase his wet diet so he hydrates more and paid it with forti flora every now and then, and occasionally slip him his gabapentin when it's a stress day (especially fireworks or vet days.) helped with diarrhea and that mega helped him I greet him every time I walk past him especially if he notices me or meows. And if I have energy play with him or encourage him to play with toys. But the final things thats helped BOTH of my cats settle down with anxiety was feliway. ## Frequently Bought Together - FELIWAY Optimum 3 x 30 Day Cat Calming Refills for Pheromone Diffuser, 3 x 48ml Value Pack - 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.sk/products/415236120-feliway-optimum-cat-calming-pheromone-diffuser-refill-3-pack](https://www.desertcart.sk/products/415236120-feliway-optimum-cat-calming-pheromone-diffuser-refill-3-pack) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-15*
