FELIWAYClassic 30 Day Cat Calming Plug In Pheromone Diffuser Starter Kit, 48ml - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming

We recently upgraded to the HHOLOVE automatic litter box in our multi-cat home, and while most of our cats adjusted well, one of them became extremely stressed—so much so that she began urinating on the carpet and avoiding the area altogether. After speaking with our vet, they recommended trying the FELIWAY Classic Plug-In Diffuser to help ease her anxiety.We plugged it in near her designated space and within just a couple of days, we noticed a major shift in her behavior. She started to relax, stopped the inappropriate urination, and began using a standard litter box we placed just for her in a calmer environment. The best part? She’s now slowly beginning to explore the new robotic litter box on her own terms, without fear or panic.This diffuser has made a huge difference in helping her feel safe again. I highly recommend it for any pet owner dealing with changes in the home or signs of feline stress. It’s subtle, effective, and absolutely worth it.

I truly was very skeptical about getting this product. I volunteer at a shelter and all the cat folks who foster said it was great.All the rescue folks I know recommended getting it from Amazon, by the way and I've been very happy with price etc. Some people have said the diffusers fall out of the wall socket. I just pulled the prongs apart and didn't have any problems. Others have suggested putting on a timer, which sounds like a great money saving idea.Here's my story:I had, in 2012, my black cat Rufus (who's probably 10) and my stepkid's two cats, about 5, male and female littermates. I had been keeping them all completely separated for over a year. Finally, I decided that is stupid and unfair to the sibling cats. The female is not very friendly and can extremely "witchy" so I was very worried. She could be a real pain!Note: We live in a 1910 era home with low ceilings. If had high ceiling, I'd add more diffusers. And all the cats were spayed/neutered.I put one Feliaway diffuser in the basement near my cat's litter box and food and one on the second floor in the littermate's room by their litter box. I probably should have added a 3rd one on my first floor in retrospect. And I should have added one more litterbox and invested in a really decent large cat tree. (But I digress....)I open the door to the littermates' cat room and let everyone roam freely. I will say I separated them at night, putting the sibling cats back in their room with a Feliaway diffuser. I did this so Rufus and we could have a break as the step-cat were extremely nocturnal.I will say it took about a month but the male cats started napping on the same bed. It took about 2-3 months but eventually all the cats could be in the same room together without being stupid and hissy. I do have pictures of all 3 on the same bed, napping. As an added bonus the female was nicer to humans as well.About a year ago, the step-cats moved out and I stopped using the Feliaway for my black cat. I still had the diffusers and and refills left. In Jan. 2013, at the last moment (without warning) the step-cats plus one (an evil Siamese) were in our basement. So now we have the littermates, the Siamese and Rufus our cat all together. There was a whole bunch of hissing, swatting etc. It wasn't pretty. I did remove our cat Rufus from the basement to de-stress him but even so it still was ugly.I plugged the diffuser back into the basement, added a litterbox and within a day, the three cats were fine. Not best buddies but fine. I kid you not, it was in a day.Two weeks later the three cats left and I gave my stepkid the Feliaway diffusers as she was moving into a new place. She said it made a HUGE difference. She could tell when it ran out because the tensions ran high.I'm ordering more because our own cat Rufus has had some anxiety issues and I really do believe that putting another Feliaway diffuser upstairs where he hangs and has his litterbox and food is going to help calm him down, especially as we are going to have pet-sitters in the house.The upshot of this incredibly boring story is the Feliaway diffusers made a huge difference when we had multiple cats. Even my husband, a huge skeptic, admits that it works very well. I think it will help Rufus as a single cat too.I was a total skeptic. I'm a believer now.

Short version:PROS - VERY effective at reducing stress levels and decreasing inappropriate behaviors.CONS - The diffuser refills are only effective for 20 - 25 days (Two other relative, in separate homes, also report they only seem to be effective for 20 to 25 days).- The cost. VERY expensive when using the recommended number of diffusers in the home and then having to change them sooner than the recommended effective date.Long version:I have seven cats who, while have free access to a large fenced yard and limited access to several hundred acres outside of the fenced yard, primarily spend their time indoors. There are conflicting personalities between them, in addition to added stress of intruding strays. With the high stress levels came spraying indoors and increased aggressive and inappropriate behaviors.I use 3 Feliway diffusers, one at each end of my home and one in the basement. It has literally saved their lives and my sanity. The diffusers do not last a full 30 days for me, usually around 25 days. I can tell when they are no longer effective, as the bad behaviors escalate. It's not immediate...It takes me about 3 days to figure out why the spats and spraying have become noticeable, when I check the diffusers (I write the approximate date for replacement on the refill bottle)it is close to the change date. Within one day of replacing the refills, all is calm again.I also have found the spray to be VERY effective in discouraging marking/spraying when applied every two to three days to the preferred objects. When applied to a pair of leather gloves that I use to "handle/pet the feral strays, it is extremely effective in calming them and reducing the number of "strikes/bites" to the gloves. It always amazes me to watch these very feral cats calm to the point that they not only allow me to pet them but relax enough to roll on their back for me to rub their tummy. I use the spray liberally around the area where I feed them, which also helps discourage marking from both my cats and the strays.And I really mean it when I say it is a life saver. About 6 months after moving into my new home in the country, an intact male stray (that I had neutered and named Melvin) decided to make himself a home with my four other cats (three females and one male, all altered). Being an adult (estimated 2+ years), it initially cause some tension with my other cats but eventually we all settled into a fairly stable routine. However, I had to continually work with Melvin to lessen his aggression during play.About two years after that, my best friend was in a bad car accident, and while she survived, she could no longer care for her three cats...so I adopted them. Even though I took 2 months to slowly integrate them, they created tension among my 5, especially Melvin. Over the next year, Melvin's stress levels increased to the point of spraying, aggression and overall depression. I tried several medications (my sis is a vet) but to no avail. His spraying became uncontrollable, to the point where he deliberately sprayed objects next to me, and eventually ON me. While he never really got rid of all of his stray-tom mannerisms, it was as if something sort of snapped in his brain, that while he wasn't mean, he was simply not right and definitely not happy. Having exhausted all other solutions (even using Feliway spray), I had him euthanized.Less than a week after the heart breaking euthanization of Melvin, one of my males (from my original four) started spraying in the house, and also one of the males of my friend's three. Medication did not help either of them. As a last ditch effort, I started using the Feliway diffusers and applied the spray to all spray-desirable objects on a daily basis.I am VERY happy to report that while there is an occasional marking and spat (usually aggravated by the presence of the strays), the situation remains manageable. And while I still morn for Melvin, I breathe a daily sigh of relief that I don't have to make that decision again.So, the Feliway diffusers and spray, while expensive, are most definitely worth it and a total godsend for my seven fur-children.
