FELIWAYMultiCat 30 Day Cat Calming Plug In Pheromone Diffuser Starter Kit, 48ml - Helps Reduce Conflicts and Signs of Tension in Multi-Cat Households

I bought 3 of the Feliway Multi-Cat Diffusers because it was recommended by pretty much everyone I talked with and did research with. I did a deep dive on all the reviews, and since most of them were positive I decided to go ahead and order them. We have 2 cats that we had just introduced to each other, and we had been at our wits end to try and get them to calm down. When the diffusers arrived, we plugged them all in. 1 of the 3 started smelling really weird, and we unplugged it and let it sit for a while. A few days later I noticed the liquid leaked out all over the outside of the bottle, and there was no liquid left inside it. We were able to return it no problem, and the other 2 plugins had absolutely no issues.Now when we talk about how well it worked, I did notice a change in the cats pretty quickly. It wasn’t huge, but it was a sign that it was working. We had also bought the Feliway Spray and would spray certain spots in the house and put it on the cats collars. So we were doubling up so to speak. The spray and the plugins DID work a bit, but it didn’t miraculously fix their relationship. Over time it seemed the cats got used to the smells as well and possibly were starting to build a tolerance to it.To be able to refill them, you DO have to buy individual refills. That wasn’t something we were wanting to do as that adds up with money, and it just wasn’t worth it for us.Be careful with how you hold the product, and make sure you’re holding it straight up and down otherwise it can spill and leak. Don’t plug it in around or under ANYTHING! I’ve seen reviews saying it ruined something or got on something, but the directions tell you specifically to not plug it in below or around anything.The product does get warm to the touch, as it heats up to be able to diffuse the scent. So please keep that in mind when handling it!Outside of the plugin we had to return, none of the working diffusers smelled praise God.I would recommend Feliway diffusers and sprays as they are likely to help at least a little bit, but keep in mind that each cat is different and can react differently to these products. I would say that this is a temporary fix rather than a full on fix. My mom and I pray over our cats, and that works wonders!

Highly recommend if you have multiple cats!I have 3 cats Allen (5), Millie (2), Chrom (2.) M&C are from the same litter, adopted March 2024. Allen I got when he was 6 weeks old.Allen and Millie fight like Tom and Jerry. Every. Single. Day. Someone on Reddit recommend this product to me because Millie started peeing outside of the litterbox because Allen would attack her. He would full on chase her down and rip out her fur. I gave this a shot and ordered it June 15th 2025 and for a whole month it was peaceful. Millie started using the litterbox again and Allen, mostly, left her alone. It went from constant fighting to every once in a while.Today is July 15th and I’ve noticed they’re starting to fight again. So I just ordered a refill bottle. I will say that the last bottle did not make it the full month. There is still liquid in the diffuser and when I went to pull it out the outlet it got on my hand. So I think it leaks. But I didn’t notice a smell or any noise from it. I wish that it worked for human kids haha.Anyway. I will continue to repurchase this as long as it continues to keep the peace between my cats.

So first, the overheating problem. I thought maybe people just weren't plugging it in correctly and that's why it would get too hot. I did what another review suggested by buying a surge protector and plugging it into that. It still gets way too hot for my liking. So I only could keep it going for about 8 - 12 hours a day. Basically during daylight hours, when I was home. I thought the level of hot it got would be okay. It seemed to get as hot as my router does for my wifi. Which is hotter than any router I've ever had, but it's never gotten hotter than it does, nor caused any issues. So I thought maybe this would be similar. But after about 3 days of use, you can see the inside plastic starting to warp from how hot it gets. That's not safe at all! So imagine continued use, 24/7 how hot and melted that plastic will get and cause huge issues.So second, I did not have issues with it dripping like others complained about. I made sure it was completely upright and nothing under it plugged in. I made sure to screw the container in tightly and not tip the system in any way. I made sure to handle it always upright to avoid spilling.So thirdly, if the product works best leaving it on 24/7 and it can't be left plugged in due to potential over heating, then there's no point to buy this product until they do something productive about the problem so many are complaining about. I noticed no changes in behaviors of my stray momma cat I'm trying to calm down. She's flipping out to all the changes of being inside my home. I have 2 senior cats I'm keeping separate in the rest of the house, and keeping the momma in my living room. But they can see each other under the door. Not only is that flipping her out but I was told that neighbors are calling the humane officers on strays and that if I didn't want my cat taken away I should have her rabies tags on her when she's out. Welp, I haven't gotten that far into helping her. So she has no tags and can't until she's done feeding the babies. Which are only a month old. So point being, I've only been able to let her out at night. Which she saw a racoon and is now flipping out about being inside all the time, but also about going outside now. I really wanted this to work, but it's basically snake oil. I even tried rubbing it on my hands to let her sniff it since they claim it's like the pheromones momma cats put out. I thought maybe she'd calm and think I'm her momma cat. But it's not helping. She's still sitting meowing a bunch and panting like she's hyperventilating. I'm hoping once she gets spayed that will help calm her some. But clearly this stuff isn't going to help me out.Be warned, they don't allow returns on this. I figure the reason is, they know they are selling a defective product. So unless you have money to waste, just don't buy this. Believe the bad reviews and try something else if you can.
