These work great! Living in apartments with 2 cats, I’ve used them since we got them. HOWEVER, if they go out before I get more we do start to notice some slight behavior changes. Not enough to be alarmed but enough as a helicopter pet parent to notice. So do with that information what you will, but Defintely recommend for moving, firework holidays and if you’re leaving on vacations since they do make theses times 89% easier

Feliway Stat!

Unfortunately my auto ship didn’t have Feliway because it was back ordered and this was the suggestion to replace the missing order. It was useless! I have my mother’s 12 year old cat which I took in after my mother’s passing. She is a bully mostly because she is anxious and terrorizes my 5 year old cat almost 24 /7 Feliway helped ease the anxiety this stuff doesn’t! I could put any air freshener and would get the same result!

It works well

This product seems to help our feral cat and our alpha cat get along better. They seem calmer with continuous use of the Thunderease diffuser. The feral has progressed to sleeping on the bed now, instead of under it. He spends more time relaxed, instead of constantly scared. Will continue to use ThunderEase diffuser into the future, long term.

Poor Product

This product does not work for my cats! One of my cats was actually attacking the other two after I plugged the diffuser in. I have used similar products in the past and never had a problem before. I have asked to return the product.

Chewy is Awesome

Chewy is Awesome. Once again in one week three orders, on a Fed Ex truck, arrives before scheduled and in excellent shape! I purchase the ThunderEase for my very high-stung Calico Miss Ellie. There are many kitties that use my back yard for a main access road to wherever; and it really ticks my indoor kitty off. The ThunderEase used to work very nicely by itself; but, now that my kitty is now 16 years old I have had to medicate her as well. The ThunderEase works excellent on younger pets, but not quite as well for the older pets in my experience. I am still using it, it does help.

OK but it's hard to say

How well this product works is hard to evaluate and any conclusion would be subjective on the part of the observer.

ThunderEase multi cat diffusers

I have used three different types of diffusers... Feliway [which apparently makes ThunderEase] and another... I continue to purchase these as they seem to have the best impact on my trio of very diverse felines.

Does not work!!

This calming diffusers are a rip off. For something this expensive i expect it to work well. It says it lasts for 30 days and the one i used it didn't even last for 20 days. My cats are still spraying the walls, that’s the reason i got it for. So disappointed .

Bad Reaction

I’ve used Feliway for years and never had a problem. I decided to try thunder-ease due to better price. Well within the first day I had a terrible reaction of dizziness, rapid heart beat and confusion. It occurred to me the only thing that changed in my home Was the plug in. I unplugged it and within an hour I felt normal!!! Of course I read the warnings after the fact and sure enough it’s in the warnings. Beware!
