Reviews

Super calming

"Freddie is so much more relaxed and more content since using Feliway Optimum. It seems to make him especially affectionate and more sociable as well as reducing scratching behaviours! My only criticism is the amount of plastic with the refills. It would be amazing if there was a refill option to reduce plastic waste."

— Sarah K. (4/5)

Calming influence

"We have 3 cats. , 2 of which are male. They have come to live with us as different times. The 18 year old male is jealous of the younger male & sprays. This does seem to have helped. I use one in the lounge, one in the kitchen & one on the landing. Now on my second set of refills."

— Deborah (5/5)

Happy cat, happy house

"My 20-year-old kitty is more agitated as she's gotten older but Feliway Optimum has really helped her feel more relaxed day to day. Highly recommend!"

— Emily S. (5/5)

I rescued two cats kittens

"I rescued two cats kittens that were feral. I got two Male cats that have just reach adolescence, the diffusers has helped a lot with territory issues from one cat who has not been liking other cats near our home. He started urinating all the time all of a sudden, and not using his tray, I bought the diffusers and he has just stopped. My cats are in urgent need of nuetering. But I am very thankful for the diffusers, I will also keep using one just to help them adjust, they are taming beautifully. If it wasn't for the diffuser I do not know what I/we would of done. I highly recommend but you must follow instructions properly."

— Nichola W. (5/5)

Calming

"My cat would hiss at other animals but seems to be calming down."

— Linda (5/5)

Brilliant

"By far the best feliway diffuser I've tried."

— Sue A. (5/5)

Fantastic product

"Great, we had numerous issues with our cats. Spraying, Urinating all over the house, fighting, scratching furniture, meowing constantly, hiding from the young kids, not eating properly, The cats have really relaxed since we used the plug ins. We have a three storey house & have one plug in centrally located on each floor. It is nice to know that its relaxing the cats & we don't notice the plug ins are there."

— Amanda (5/5)

Sharon and Oberon

"Baz was our Tuxedo cat. When Baz was overrun by a speeding car, his sister Sharon, a ginger domestic shorthair, was very impatient, feeling the absence. She urinated on bed and alwsys looked at catflap for Baz to return. We introduced Oberon, a rescued Tuxedo kitten who was born on the same day when Baz died. We were very worried about the introduction of the two, so I got a 6 month subscription of Feliway Optimum Diffuser and Happy Snack. I share their snack together and diffuser is on the wall plug. Oberon and Sharon are now best friends as the photo suggest. I took the photo right now in the same room that the diffuser is placed."

— Hossein G. (5/5)

Felixstowe Optimum

"Does seem to be making a difference her hair on her legs has started to grow back with her grooming less"

— Stephen (4/5)

A useful addition

"I have 2 cats, a mother and daughter duo where the mother cat constantly bullied her daughter. This resulted in all sorts of health problems. Luckily the vet asked about behavioural problems and I told her about the bullying. She recommended Feliway and the bullying stopped! Unbelievable, I know, but it was that dramatic! I have continued to use Feliway Optimum since that day, and life has been so much quieter."

— Bry M. (5/5)
