Review: Absolutely purr-fect for my kitty. - I have to admit. I was skeptical about this simple thing could or even would help my sweet kitty. When we adopted our kitty Peppa, she had been surrendered to a cat shelter when she was just about to have a litter of kittens. By the time we heard about her she had already weened her kittens and was spayed. This cat shelter offers a cage free environment for the cats so they feel at home, moving from place to place freely inside their building. People can move about freely among the cats until they find the cat that appears to be drawn to them. Peppa found us so we adopted her. She became a part of our family. My husband and I are retired and at that time we had 2 yorkie pups, brother and sister. It took a few weeks but eventually the pups and kitty all adjusted nicely to each other. She is an indoor only kitty. At first our kitty seemed happy and did well as an indoor cat. But then we started noticing patches of her fur seemed to have been chewed away around the base of her tail and her lower back. There were even bite marks that were bleeding or scabbed over. We took her to our vet and they immediately prescribed drugs to treat a possible parasite. These meds are very expensive, but to our credit, we thought we were doing the best for our cat. But even after months of giving her the meds, she only seemed to be getting worse. She had pulled out almost all of her fur from the base of her tail near her back, on her belly, and between her back legs now too. I thought there had to be something better out there. Something that actually works without costing a small fortune. So I did some research. I found that you can literally spend thousands of $ trying to figure out why your cat does this and never come to a conclusion. I read that it could simply be separation anxiety from other felines. If you have 1 cat in your home, they may feel overwhelmed and begin chewing and biting their skin. A type of nervousness. Often times, simply getting another cat will resolve the issues. But it is not always possible for a person to have more than 1 cat. The research I read suggests that it’s cat pheromones that seem to be the issue with some cats. That’s where Feliway comes into view. I learned that the feline pheromones in the defuser is what seems to work. So I bought 1 to try, plugged it in and after only a week into the first defuser, I was sold on it and was shocked to find that it was actually working. IT ACTUALLY WORKS!! If you have a similar situation with your cat, I highly recommend this defuser. ## Features - HELPS REDUCE CAT STRESS: FELIWAY Classic is a cat calming diffuser that helps individual cats feel calm and reduce stress behaviors like scratching, urine spraying, and hiding - CREATES A CALMING HOME ENVIRONMENT: FELIWAY Classic uses calming pheromone messages that cats naturally understand to help them feel comfortable and safe during everyday changes in routine or environment. 9 out of 10 cat parents noticed reduced urine spraying and 8 out of 10 saw reduced scratching - SAFE* AND NON-SEDATING: FELIWAY Classic is not a sedative.

I only have ceva feliways diffuser. But looking at the diffuser, I think I could put a refill in Bath and body works plug-in diffuser, meaning I think they are pretty standard. I would try comfort zone's diffuser if I needed to, tho. **Q: Is it possible to use the Feliway liquid at the bottom? the diffuser never uses all of it.** A: I pop off the top on my feliway bottles and condense into another and am able to fully use it. You’ll need a flat head and a couple of paper towels bc it’s a bit messy but if you do this you’ll use it all! It’s worth the 5 minutes, I usually get another two weeks worth out of the bottom. **Q: What is the difference between feliway classic and multicat?** A: Classic is a facial hormone which is calming. When cats greet each other they rub cheeks as a friendly gesture. Multi cat is a mammary gland hormone and since kittens nurse together, this helps to reduce stress in cats who live in the same household. **Q: What's the differance between the Feliway from comfort zone over this Ceva Feliway defusers** A: 1) Ceva manufactures Feliway, which was the original feline pheromone calming product. 2) Comfort Zone With Feliway contains lower quantities of Feliway. 3) Comfort Zone is less expensive up front. 4) In my experience over the last several years: 4a) For mild/moderate situations (or cats with mild/moderate issues), Comfort Zone helps. 4b) Feliway by Ceva is more effective for severe environmental situational (highly stressful/more chaotic, etc) and for cats with more severe or long-standing issues. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It Helps!! *by J***N on April 29, 2026* Excellent, helped my timid cat so much!! ### ⭐⭐⭐⭐⭐ Absolutely purr-fect for my kitty. *by T***L on March 22, 2026* I have to admit.

Leaks a little though. *by M***A on February 3, 2026* Got this for my bedroom as my cat is very nervous, skiddish, and pees on the bed. It was getting pretty bad, I’m talking every other day almost! Literally since the day I plugged it in, he has not had ONE single accident! I’m trusting him on the bed now for cuddles. Very effective, love love love this! I will note, the plug-in is bulky and kind of leaky, I see oil underneath it on my wood floor, but it’s not ruining it. Just something to keep in mind, maybe keep a towel or something underneath if you want. The smell isn’t crazy, kind of like a faint wood/cardboard smell. Makes no noticeable noise. Overall great product. Definitely will keep buying. ## Frequently Bought Together - FELIWAY Classic Cat Calming Pheromone, 30 Day Refill - 1 Pack - FELIWAY Classic Cat Calming Pheromone Diffuser, 30 Day Starter Kit (48 mL) - FELIWAY Classic Cat Calming Pheromone Spray (60 mL) --- ## 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.hk/products/24740256-feliway-classic-cat-calming-diffuser-refill-1-pack-30-day](https://www.desertcart.hk/products/24740256-feliway-classic-cat-calming-diffuser-refill-1-pack-30-day) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-16*
