    • Yes it works, Optimum v. Happy Cats, range, etc.
Color: Translucent Size: 1 Pack
Was recommended this product by a volunteer when adopting a feral kitten. I knew I’d have my work cut out for me and figured every little bit helped. So I got this ahead of time so it would be set when she came home. Fast forward a month. This little gem of a kitten is bopping around the home with my resident cat, pleased they were fast friends. And then out of the blue they began having some hissing squabbles turned physical fights over the course of a few days in the play area. This hadn’t happened since they first met. What the heck?? Then I realized the plug was empty. I put in the refill and by the afternoon and thereafter that behavior hasn’t surfaced again. I share this story because for this house, this product didn’t work miracles when I plugged it in. It still took a lot of patience and slow integration to bring these kitties together and for the kitten to feel confident in her new space. But it IS objectively a product that is noticed in its absence. The behavior was there when this plug was out, non-fighting kitties when in use 🙌 this is worth it. A couple things I wish I knew to begin with when deciding whether to jump on train feliway: 1.) the range of each plug extends up to 700 ft. I ended up ordering a second one and put them on opposite ends of the house. If your cat(s) have an isolated ‘hot button’ room or situation where they regularly have issues (like the master bedroom, at meal time in kitchen ie) you would likely be fine plugging the one in right in that area. If your kitties/cat has an overarching behavior/pattern you’re trying to manage, keep a close eye on that range to see how many you may actually need. 2.) After also trying Feliway’s ‘Happy Cats’ Multicat refill, this Optimum formula performed better here (optimum: 1-2x play fighting-turned-real fighting per month, whereas with the Happy Cats this was still happened 1-2x a week.) 3.) these plugs don’t last forever and will begin not putting product in the air. Instructions say these need to be replaced every 6 months. This is one of the few things I have on auto-ship to remind me to change the unit bc I will undoubtedly forget when I changed it last. 4.) I’ve had no issues with the plugs up to 6 months of use. They are super consistent at running out between 29-31 days. ... show more

    • I'm amazed- it seems to be working!
Color: Translucent Size: 1 Pack
I have 3 cats, and foe the last 3 or 4 months, I've been in a middle of the last big move of my life. If you have cats, you know they don't like chaos or disorder or messes-- or change of any kind. And they've had to be put outside when people came to view our house (we're selling to move across the country). They prefer to stay inside, except the 1-year-old. My other two are around 10-11 years old- and one of them "sprays" when he's upset. As my living room and other areas started to be packed up and moved to the garage, I noticed he had "marked" my treadmill. My daughter recommended this, she said it worked wonderful when they adopted a feral diameter they found while camping. I honestly didn't have high hopes for this. It's plugged in by my treadmill right now- I wish I didn't have to plug it into a power strip- it's designed for a wall plug. I didn't know how far the range would be. These pheromones are something only cats can smell. Being spring, I have the door open a lot, but despite that, it seems to be working! My orange Tabby hasn't sprayed, and I even gave away the sofa they loved. Nothing is even left in the living room except boxes of records, boxes of wall mirrors, and 3 record cabinets. It's really a mess,but despite it all, my cats seem calm. I wish this came in a plug I could use in my car- I'll be driving the three of them and my Jack Russel Terrier across the country in a very full mini van, and I'm really worried about that... I definitely recommend this product. I will be looking into their other offerings, hopefully there will be something I can use on the van- that could turn disastrous very fast in any number of ways. This container-I have it plugged in full-time, sideways- will hopefully last 3 months. My daughter says they last "a few months", but I don't know if she unplugs it sometimes. It's a little expensive, but so worth it! It has a nightlight, and glows a lovely green. Heat is not an issue either. It's about the size of a Glade Plug-in, a little bigger. ... show more
