FELIWAY® Optimum 30 Day Cat Calming Refill for Pheromone Diffuser, 48ml - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming

This helped when I got my youngest and helped both of them adjust. Also helped them not go full Cain and Abel when I went on vacation. I don’t smell anything. The heat doesn’t damage anything. It doesn’t leak or anything like that. Easy to use and set up. It’s similar to a regular plus in. I get refills as needed now that they’ve gotten used to each other. So usually just for when I’m not home to help relax them and keep anxiety low. It would be super bad in the house without Feliway. It does work. It’s worth it. They’re relaxed which makes me relaxed. Relaxation central thanks to this stuff!

I adopted a brother/sister bonded pair. We discovered that the boy was playing so hard with his sister that he was often drawing blood. We couldn't have this so this product was recommended to us. It works very well, mellows him out. We can always tell when the product is running down because his mood ramps up again. Only down side is this product isn't cheap and only bottle doesn't last that long, about 20 to 25 days. But if it keeps one cat from loving to death so that we can keep them together and with us we will make that sacrifice.

I had tried Feliway Multicat in the past when we adopted a new kitty, and our resident cat felt his territory was shrinking. We used it in 2 different points in our 1050-sq. ft. apartment to ensure coverage, and it seemed to marginally make a difference. I wasn't exactly sold on Feliway (were these improvements coincidental?), but wasn't disappointed either (a change in behavior did occur within 48 hours of plugging the Multicat in, so... maybe?).Fast forward to this fall, and my boyfriend is out of town for 2 months taking care of family things back home. Our cat Bubba is most bonded with him rather than me, so the absence has been stressing B-Man out big-time. He became constipated, only doing his business every 2-3 days (abnormal for him). Our vet ruled out medical concerns, and all my other attempts to de-stress him did not work. Adding pure pumpkin puree to his food didn't do much, either (besides annoy Bubba that his food was tasting different).Desperate, the internet's declarations that Feliway Classic helps with stress convinced me to drive to a local pet store and get some that day. All Petco had in stock, however, was 1 refill of Feliway Optimum. I did some research on the fly on my phone, decided that Optimum's new formula of multiple pheromones in one sounded effective and intriguing, and made the sale.I kid you not, I plugged this product in on a Monday evening, and Tuesday evening, Big Man pooped. Wednesday evening, he pooped again. Thursday afternoon, more scooping action for me. 1x/day was much more Bubba's usual litterbox schedule. So I decided that, holy cow, a new product might actually work for once, "it wasn't just a scam!", and ordered 2 more on Amazon (again, full coverage for our apartment, as 1 diffuser can do up to 700 sq. ft. MAX - keep this in mind when purchasing). I've had 2 Optimum diffusers going while my boyfriend is gone, and Bubba has been less mopey, more playful, and much more regular. I'm hoping we won't need them once my boyfriend is back, as $50/month for 2 is steep, but I wouldn't swap this out for anything, not even Feliway Classic and certainly not another brand. Plus, Amazon has it here for $25/refill, and it was $38/refill at Petco, so this is still much better!! This item gave Bubba the relief he needed, so it's worth every penny to me.Side notes: I already owned 2 of the regular Feliway diffusers from our brief stint with using Multicat - the Optimum refills DO fit into a regular diffuser, you do not need to buy the special Optimum diffuser with the LED light if you don't wish to. Also, the diffuser creates an oily film on all items directly around it - I have one in our kitchen, and had to throw away the oven mitt hanging by it because the mitt became coated in wet tacky Feliway oil which did not come out in the washing machine. They can def. be a bit messy, so clear a square foot or two directly around them. Yes, they also make a shiny film on the wall by the outlet they're in. I'll do anything for my kitty and just wipe it clean when it gets noticeable, but if you're looking at using these for the duration of your cat's life, bear this in mind.Overall: diffusers can be a bit messy, seems expensive but Amazon is actually way cheaper than anywhere else, and this product is the real deal. Just try it for a month, see if it helps. I'm sure glad that I did. <3

This stuff really works and I highly recommend it. It really does calm my cat. Had 4th of July fireworks and it hardly bothered her. Live in Arizona and currently have Monsoon storms and so far she is also ok with it and is calm. It is pricey but well worth the money.

I typically don’t believe in stuff like this, but it works well for my Siamese boys. One of them seems to always be stressed out. He used to start fights with the other one and would randomly hiss at me. After installing it for the first time I noticed fewer of these incidents. Oddly enough, this behavior returns when the stuff runs out. There is definitely a calming affect associated with this product for my cats at least. There is no noticeable smell and I don’t even know that it’s there.

As a veterinarian I recommend this product a lot. I do believe it helps calm some cats. This is my first experience actually using it in my house and am only giving 3 stars because the refills did not last 30 days. I am not convinced it is worth the money

I don’t know what kind of cat sorcery is in this stuff, but Feliway turned my drama queen furball into a zen master. One puff of this magical mist and suddenly she’s no longer rage-scratching the furniture like it insulted her ancestors. She’s calm, content, and possibly expecting room service.It’s like aromatherapy for cats, but instead of lavender and whale sounds, it's the scent of “chill out, Karen.”She went from zoomies and side-eyes to loafing peacefully like she’s on vacation in Bora Bora.Might plug one in for myself next.
