FELIWAYClassic Cat Calming Pheromone Diffuser, 30 Day Starter Kit (48 mL)

Wow! I was not expecting it to work so quickly. I’m amazed! I have an older cat and recently brought home a kitten. I know it’s going to take time for them to make a connection, and my older cat has been isolating herself for almost 3 weeks. I plugged in the Feliway and within an hour both cats were both hanging out together. Not best friends yet but a breakthrough. My older cat was back sleeping with me. This item completely calmed both cats. I’m very happy with this product! Give it a try if you have any anxious cats.

I have two cats, they do not get along with each other but they tolerate each other. One of my cats is a biter. She bites me for no reason. She was a rescue so I put up with her terrible habits. I've had her for 8 years. Sadly, I don't remember her as a kitten because she was so standoffish and had nothing to do with anyone. My vet advised me to try this to see if it could help her 'chill out'. I purchased this and got it quickly. It's very easy to use, just screw the bottle in and plug into the wall. There was no change in my cat immediately, but I did start to notice changes within 2 weeks, she would come out and sit on the sofa, she - very slowly - started to become more sociable. She and my other cat do not get along still, but she actually tolerates him also, doesn't like him but doesn't try to bit him....or me anymore. I started using this stuff about 2 years ago and have been using it ever since. The atomizer does wear out after time, and I realized my cat was getting back to her old ways. I checked the atomizer and it was still almost full. I noticed after about a week that the atomizer was just not working anymore. I read that they do wear out so I bought an off brand atomizer claiming to work with the particular product. It did not. My cat was becoming unsociable again. So I bought the name brand and it is again working for my cat. She actually sleeps on the bed with me at night, something she never did before. She's really a sweetheart but she just needed some help. I'm not sure how this stuff works to make cats calm down but it is the real deal. My only complaint is that I have lots of refill bottles, I only needed the atomizer that plugged into the wall. Feliway does not sell the atomizer alone, so I had to buy it with another bottle of Feliway, which is OK, I will use it, but just wanted the option for the replacement part, which is why I gave this product 4 stars for value. Otherwise, will use it for life.

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.
