Snow went from Cujocat to pussycat

We have a partial feral cat who can be wonderful but will bite and scratch me. We also have another street cat named Jade that is very calm. Well, we used different "calming diffusers" which help with Snowie. We ran out and tried this. Amazing. This worked in about 4 hours. He is now my pussycat and very affectionate (few hisses). He also quit immediately attacking Jadie. This brand seems much better. We have to use it or our cat is like "Pet Cemetery" or even a Cujocat. Otherwise, he is a complete sweetheart.

Peace in the house!

I bought this because the oldest of my 3 cats had surgery and I was afraid recovery and being in a cone would exacerbate 2 other stress-induced conditions he has. Though I didn't have a frame of reference because he's never had surgery like this while we've had him, so I wouldn't know for sure if it was working. But I did notice positive behavior changes in my 1 year old and 4 year old cats! The younger is very playful and will annoy the 4 year old-typical little brother stuff. The 4 year old would hiss and swipe at his little brother even if he wasn't doing anything. After I put the diffusers in, I've seen a 90% reduction these behaviors. They seem calmer and more comfortable sharing the same space peacefully. So I'm not sure if it's working on my senior cat- he's acting great but I'm not sure if that's from the diffuser or the surgery gave him relief. But the changes I've seen with the other 2 is a definite win and I'll buy more!

Mixed reaction

I bought two Feliway Optimum and placed them in the rooms the cats frequent the most. I plugged them in on 2.27.23 and at first thought, it was working because they were all pretty mellow. One cat is the worst and goes after the ones lower on the totem pole and he can be vicious. They are all spayed and neutered yet there is a conflict between them. Anyway, I don't know if it's working or not. I did purchase two refills because I read it can take up to 30 days to take effect.

amazing for older cats

My two older cats are now so relaxed and calm.. I love this stuff! I’m happy my 13 and 15 year old babies seem to be happy and comfortable. Because they’re older, they need special diets and supplements for their physical health. I really wanted to find something that could help their mental health, anxiety, and other behaviors that come with old age. This has been absolutely game changing! Been using this for months and their anxiety is almost nonexistent now. They get the best foods and vitamins and now they get the best care for their kitty anxiety too! Was skeptical at first but now I wish I would’ve tried this earlier. This stuff is worth every penny and I will never be without it again! Seeing them as happy and healthy as possible puts my mind at ease. Don’t hesitate! Just try it!

Great Produc

I got the Feliway Optimum because one of my cats, Winkie, can be quite anxious. when I started feeding a feral cat and Winkie watched from a window, he started peeing in the house. was yelling at the cat and sniffing at the door where the cat would come and sit. I don't remember how long it took to take effect but it was just a matter of days not weeks.

hiding my review

Chewy has always been good at posting reviews even when they're bad, but for some reason they're hiding my review, I bought this with the thunder wonder my cat was pulling his hair out and obsessive grooming. I had called the feel away hotline they said they had not heard of this but I have taken out the diffuser when this started and stopped giving him the thunder wonder and he is no longer pulling out his hair and obsessive grooming so one of those items did it. I'm disappointed in Chewy for hiding this they have always been wonderful. I guess they don't want my review of what one of these products did to my cat!

Expensive, Disappointing

I have FIVE cats, including a calico who thinks SHE is in charge, need I say more? I have been using this for six months, we are up to FOUR diffusers in my 1100 sq. Ft home. Very little difference in behaviors. Tried 'calming food', also TOO expensive. My aggressive cat is now on gabapentine, which worked nicely for a friend and her cats( she only had to give it to the aggressive cat for a month. I think this woll be alittle harder case bc more cats). If you feel you must try this, try one, or two, at opposite ends of house, and using an outlet that is not blocked by anything or furniture. Good luck. It didn't work for us. :(

AMAZING it really works

I was skeptical at first but when my new kitten was having separation anxiety the vet tech recommended I try this. Within HOURS she was napping more and when I was gone my roommates said she was perfectly quiet instead of meowing for hours strait. Highly recommend to new pet owners who don't know what to do!

Disappointed, seemed to heighten aggression

I got this product at the recommendation of my vet for helping my adult cat adjust to a new kitten. They say it takes up to 30 says to start working, but behavior changes should be noticeable in as little as a week. What I noticed the most with this was an increase in aggressive behavior between the kitties. Even the baby seemed to get more aggressive. I have two plugins, one on each floor of the house, and noticed that when I reduced the plugins to just one both cats were much more calm after about a week. I knew it was a gamble but for the price and reviews I was really surprised to see the behavior changes. I've since removed both plugins and have a refill that I can't use so that's another waste of money, not to mention the added stress it seemed to have on the cats.

Immediate results

I was skeptical when I ordered this item for my very hyper cat. However, after having it plugged in for just a couple of hours I was aware of his behavior improving. His constant meowing, scratching, and prowling improved dramatically. I have always had good service from Chewy, and as with this item, the cost was lower than at local pet store. I will definitely continue buying this item, and other products from Chewy.
