Does this help with two male cats that atent neutered?
Answer by ChewyMar 29, 2018
We'd recommend using the MultiCat system in the room where the cats frequent the most, it should help calm and reduce tensions.

I first saw these in my Vets office. Was skeptical, but put several around the house. (I do Cat Rescue, and have a mini cat hotel in progress) The results were noticed within a week. With so many diffusers a large economy refill bottle would be nice :)
Answer by ChewyJan 19, 2018
At this time, this refill is only available in a 48 milliliters bottle.

Does it matter if the outlet is higher up on the wall or does it have to be closer to the floor?
Answer by ChewyMay 15, 2018
Plug diffuser unit into the room where the cat spends the most time. Avoid plugging in the diffuser under shelves, behind doors, behind curtains, behind furniture. Doing this will impair diffusion.

Is it okay to use the multicat refill in a diffuser that originally had the classic used in it?
Answer by ChewyDec 24, 2020
Feliway Classic and Feliway MulitCat refills and diffusers are interchangeable.

It's great but

I love this product. My 19 yr old cat doesn't deal with change well. Unfortunately, we have been to Texas from Maine and back and forth repeatedly for the last 2 years due to family illness. So finally our last trip was too much for her. She started peeing my bed and bathroom rugs. She's a great girl. This is not normal behavior for her, she's expressing her feelings of not belonging, trying to figure out which is home. I put in pheromone diffusers in 2 rooms of my little apt and she stopped. The diffuser ran out and she started again. Believe me, it sooo frustrating to wash and rewash but I refilled the diffuser and everything is fine again. So if your baby is showing unpatterned behavior. Try the diffuser. I had this problem yrs ago with her and was able to end it after a couple weeks. It may take longer this time or she may need it indefinitely but she's worth it. Oh, by the way my male cat picks on her regularly, that has stopped as well. They just need a better sense of security now. Highly recommend. Wish it was more affordable.

Plug in closer to cat level

My first snafu was plugging it in upside down. I noticed it leaking and remedied the problem. The diffuser jar has to be on the bottom. My mistake. That said, while it seemed to have a calming effect on a couple of scared foster kittens that I recently had, I’m not entirely sure it works with my older cats. I have my diffuser in the kitchen where arguments tend to arise around meal time. It’s about 4 feet up in an open area. I live in a 170 year old farmhouse where electrical outlets are aren’t overly abundant. Maybe it works better if it’s closer to the ground? The outlet by my foster tent was about 15” off the ground, much closer to cat level.

this works for my insecure cat

My female cat is prone to spraying, and will sometimes pee outside the boxes on purpose. This was recommended by my vet as a supplement to other strategies relating to litter issues. These keep the pee in the boxes. The capsules must be promptly replaced to keep my cat's issues suppressed. It doesn't have any noticeable smell. To me, they are worthwhile. I try to buy in bulk or when on sale.

Just Wonderful

The Feliway diffusers truly do work. I was having problems with spraying in the house after my Father moved in... all female cats. Needless to say I was flabbergasted. After 60 days of use, the marking has dropped dramatically. There have only been two small instances. I also use the Feliway spray for extra calming in the areas that the girls have marked before. (I used isopropyl alcohol to clean the areas) Additionally, they are wearing the Feliway collars. Thank you Feliway for this product. Now if there was any way to get the price down, that would be great!!

Really works

I have been using this Multi-cat Feliway for several years. I have 4 cats ranging from 7 yrs to 19 yrs. Sometimes the type A cat chases everyone. I think this has really calmed her down. I also brought in a feral male (neutered) who made my male, also neutered, skittish. After several months, they both have calmed down and sometimes actually play. When you see this in your vet's office, that says a lot. It must be good to calm down cats!

calm kitties

I’ve used this product when we moved into our new home and within a few hours cats started to roam the house. Currently I’m dog sitting a bigger dog then I normally do and I got the plug in.. hours later these silly kitties are roaming the house like the dog doesn’t even exist!!!! This stuff is incredible!!!

The Difference is Noticeable

When I ran out of my last bottle of Feliway, my seven cats started to become more irritable with each other. As soon as the refill bottle arrived and I plugged it in, they immediately became calmer. Several of my cats have chronic medical issues that can be aggravated by stress, so their veterinarian had recommended a pheromone diffuser such as this. It really makes a difference.

Happy Cats

My rescue Maine Coon Mack and his new sister, Lilly, a rescue shelter tabby are getting along just fine. A few hisses the first day and now they are BFF's. The muti-cat diffuser is a game changer for multi- cat homes

From a Vet, know what you should expect

I love Feliway and recommend it and use it in the hospital. The problem is that it is one of those things that doesn't work reliably for every cat. For the ones it helps it can be profound. Most often, we use it in conjunction with medication or behavioral training. It isn't a miracle (for most cats). You have to put in the effort to retrain and/or medicate your cat in many cases. It kind of works like social grease, easing the emotions and reducing the friction between the cat and their environment. Before leaving a negative review, consider that every situation is different. It isn't a miracle in a bottle.

Doesn't stop my cats aggression or marking

I had really high hopes for this stuff since all the other reviews were so positive but it's just not working for my kitty. He's neutered and has been for over 6 months but he keeps marking on my bed, the kitchen counters and even right next to the feliway diffusers I have around my house. I tried tge optimum, multi-cat and classic and I've run out of hope for feliway working for him. I will donate to my local vets office or return if possible.
