How is multi cat refill different from calming cat refills?

Answer by Chewy • Sep 17, 2018
This calming refill is formulated to create a state of familiarity and security. The Multi-cat refill is formulated to create a calming environment and reduce tension and conflict among multi cat households.

Can humans smell this?

Answer by Chewy • Oct 21, 2018
Feliway Cat Diffusers have no smell. This product is formulated to mimic a cat’s natural pheromones so it will not have any effect on a human.

Will the original Feliway (which I guess is the classic) refill fit in the diffuser I had for the multi cat?

Answer by Chewy • Aug 26, 2018
The Feliway Diffuser Refills are compatible with the Multi-Cat Feliway Diffuser.

Will it stop my cats for peeing in my bedroom

Answer by Chewy • Jan 18, 2019
The Feliway Diffuser is designed as a tool to help cats cope with challenging situations, and to help prevent or reduce stress caused by a change in their environment.

Definitely not for my male cat.

I rescued a tom and had him neutered about a month ago. He super sweet and is indoor and outdoor at his own will through the cat flaps. He showed interest immediately

I rescued a tom and had him neutered about a month ago. He super sweet and is indoor and outdoor at his own will through the cat flaps. He showed interest immediately as I was taking the units out of the box and I imagine there is residual pheromones on them. A couple of hours after plugging it in I could see it was calming him down, I rescued his little sister and he was still chasing her frequently trying to mate her. About an hour later he became very calm to the point of being lethargic. I got a teaser wand to try to stimulate him which worked but after I put the wand down his head and eyes were still spinning. His nasal passages have become quite moist and he’s sneezing. He has thrown up twice since yesterday and is currently hiding in the rafters/joists of my basement. This is where he goes when he’s scared, angry or sick. I unplugged them and am currently airing out the living spaces. His little sister didn’t react to them at all. Maybe your cat will be fine but this product is a definite no-go for my guy.

Due to this winters very cold weather I brought my feral cat inside. This product has been a miracle. He uses the box and I can’t find the words to describe my joy. This cat is nine years old so he was set in his outdoor ways. Thank you for this amazing product.

Bought this to help a stressed out sick kitty that has to be in isolation. I am net neutral on it. I can’t tell if it’s helping but it definitely isn’t hurting anything. I think it’s worth a try if you need some adding calming in your life.

Product seems to work well simple to use. I have it in a small office with a couple cat trees/beds. No reason didn't get five stars was because the box was beat up since it was shipped with a large bag of cat litter and no packing paper to cushion it.

I have used all of Feliway product and they work! Optimum worked the best to introduce two new young cats to the older cats we already had. I did the most common introduction methods and used Feliway Optimum. It was amazing even though I am experienced with this. My old grouchy Siamese has done his little bit of hissing the first few days they were all allowed in the same area together. After that he played with them and was invigorated. I know for a fact that Feliway made the difference!

My cat is quite anxious, but he loves sleeping near the diffuser now, and he has stopped peeing on his favorite spot on the carpet now. I can't be sure that the feliway diffuser is what caused him to stop peeing there, but I'm positive it played a role.

I've used this in the past. I thought I would try it again to minimize fighting. It's not working and just making a mess. Thank goodness it's over my stainless steel counter top and not dripping onto my hardwood floor.

I have been using feliway for years, and at this point I always know when the bottle runs out by the worsening of my cat's behavior! I originally got it due to my Adrien's rowdy behavior and tummyache-inducing anxiety, and feliway is honestly a miracle product for him. It helps him stay calm and happy and polite. It is an essential in my household.
