FELIWAY MultiCat Calming Pheromone Diffuser, 30 Day Starter Kit (48 mL)

When I bought this, I was curious how my cats would react, since there's mixed feelings from other customer reviews I read before buying. But, I can say that upon plugging in Feliway, the cats did seem more comfortable throughout the day and tolerable of each other. Mainly, our girl does not necessarily love the male , we adopted them at the same time a week ago. She will hiss at him, never swat. He doesnt hiss back or swat he simply hides. But since I plugged in Feliway yesterday I've noticed that they were more comfortable going out of their safe space rooms, and even exchanging their rooms at times. They could stand within 1 foot of each other without conflict or hissing when they have not before. The male is being more confident and hiding less. They are now both eating full meals and both went pee & poo in their litterboxes finally!! So, yes my cats have had a positive effect during the time that this has been installed in my home. Can I say for certain that this all has to do with Feliway? No, it could be a placebo effect on myself. But, it could be that it did work for me as other people have also claimed, which I'd say it did along with a combination of other efforts to make them more comfortable in their new home. All in all , for 20 bucks I'm pretty happy! As im typing this they are both chilling in the bedroom (in their respective spaces) which is a first!

Works great. We keep three of our cats in the garage at night. One, in particular, had been bullying another one. Now they all get along. It calmed them right down.

The pheromone itself works great at relaxing our super anxious cat. I'm removing one star because we had to buy a second as a replacement; the plastic casing of the diffuser overheated, discolored, and cracked after a few months.

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.

I wasted $100 on 6 of these all around my house. I read the instructions and knew that the hormone wouldn't turn corners well, and shouldn't be hear a window, breeze or furniture. I bought enough so that all areas could be covered without having to turn corners to travel...My reason for using them was to stop an aggressive cat from attacking a scaredy cat. They did not work.By the way, people complain that they didn't last a full thirty days. Those people are your typical people that never read an instruction manual. In fact, its the first thing they throw away. I followed the instructions and placed them opposite and to the side of windows, and with no air blowing on them, they absolutley WILL last 30 days+. They don't really work...but they do last 30 days+.Anyway, upon plugging them in, for the first 24-48 hours, you will have a strong fire/smoke smell, just like when your heater comes on for the first time in the winter. However, it's more of a wood-burning smell. It made me sick so I had to stay away from them and not get near them. That dissipated, and they eventually only had a very faint smell if you lowered your head to them.As far as how well they worked, I did see a noticeable side effect in both cats. The scaredy cat hung out more in the open in her CLOSED bedroom. In other words, she was slightly less afraid and ventured out to the middle of the bed or floor. The aggressor cat started playing with toys, which I hadn't seen her do before. So, the hormone does give them a sense of well being.But, the aggressor, when put in the same room as the scaredy cat in supervised visitations STILL attacked viciously. So...fail.If you think about it, using these diffusers are not only expensive, but it's like bringing a sword to a knife fight. it's overkill and you don't necessarily get the result you want. Better to buy the Sentry Calming Collar sold here on Amazon and limit the hormone dissipation to being right under the cat's nose as opposed to forcing everyone in the house to breathe it.As for the collars, they use the exact same synthetic hormone but they too won't stop an aggressive cat (and my cat isn't really aggressive. She's a mild, scared-of-the-rest-of-the-cats sweet heart who only goes into attack mode when around one cat). These collars are best used to gently calm a cat that is going for a car ride to the vet or across country. They aren't safety collars and they are very hard to adjust, so better to do one of two things: 1. Cut off the hardware and then attach the blue medicated collar to a regular safety cat collar with bread twisty ties, or 2. Don't even put the collar on the cat. Just close the loop and throw it in the carrier with the cat or attach it around something inside the carrier of the cat. Much cheaper option as well.
