NurtureCALM 24/7 Feline Calming Pheromone Collar (Upto 15" Neck)

I first used this product on my vet's recommendation when I had to fly my two cats across the US and then keep them at a kennel until I could move them into a new apartment. The folks at the kennel reported that my cats were everyone's favorite and the best behaved.Of course I thought they were buttering me up, but when I moved the cats into the apartment, I left the collars on to help them acclimate. I immediately noticed that one cat who's a former indoor/outdoor cat (he became indoor-only b/c he fought too much) who often cries mournfully to be let out as well as for his meals no longer did so and instead vocalized less and in a calmer and less grating manner -- short "meawrs" rather than long wails. Both cats also purred and relaxed more easily.When the collars expired I didn't replace them to see if it could have been the new location that changed their behaviors. The former crier began to cry more and more without his collar. I bought him a new one and the crying began to drop off. The collar doesn't work like magic though. The cat has to get into the habit of calming down with it on. Early on, it works better if you try to help it by petting the cat and comforting it. You get a lot for your effort. Once I got the crier purring with his collar on, he'd lay down and purr and purr. Soon he could get into this relaxed stated with less coaxing.Another way I know the collar doesn't work like magic is that the crier escaped the apartment one day and when he came back, he went back to wailing to go outside even with the collar on. The crying began to taper off again only with time. In the past, he'd escaped without the collar and he made a lot more noise for a longer period of time before it tapered off some. He'd still wail regularly without the collar -- even after "forgetting" the outdoors. With the collar, the crying eventually tapered off nearly completely as his memory of the escape faded.I didn't get the other cat any more collars after the trip since her behavior is generally good anyway. I do have one negative story about the collar involving her. When she tried to get the collar off of herself when I wasn't home, she got it trapped in her mouth. It held her mouth painfully open and my girlfriend was too scared by the cat's panicked state to try to cut it off, which is what I did when I got home. It may have been that I had the collar too loose on this cat though I remember tightening it to the recommended amount before trimming it. Still, I'm not sure I can blame the product in this case. I also think that a break-away collar (which this one isn't) might always come off for some cats, but I wanted to mention this incident so others would be forewarned.I've tried two other companies' calming pheromone collars because they cost significantly less. They both worked just as well as this one on the crier, but I found the sickening artificial "lavender/chamomile" scent much too offensive. I can't imagine the cat liked smelling like a recently cleaned public restroom all the time either. He did scratch at the scented ones more often as well as over-cleaned himself when he had them on. While they both calmed him down, I'm willing to pay more for this brand because it's virtually scent/odor free.In summary, this collar worked well to help a neutered 9 YO male indoor/outdoor cat be okay with becoming indoor-only.

My vet recommended this for my cat for my blocked boy's aftercare to ensure he's in as calm an environment as possible. I was skeptical, because there are a lot of collars that claim to be pheromone collars and this one was a bit on the pricier side, but after the huge vet bill I got this to try anyway.Today, my cat is prancing around the house playing with the house-mates he usually hisses at / avoids.Seeing him go from deaths door to romping around playing with the other cats is priceless, and I'll be ensuring he has a fresh collar each month as these really do work.Like other comments, I'm not super pleased with the 'quick release' mechanism, and may look into ways to modifiy it for my own peace of mind.

Got these for our 3 cats who just met and are not getting along well. They seem to work (or perhaps they are just getting to understand one another), but the big issue is that they keep sliding open.I fixed this quite easily.1) Put the collar on.2) Take a rubber band and wrap it around the end multiple times. You're only wrapping the "free" end after it has went through the buckle.3) Test to make sure it won't slip off.4) Check it about once a week, because even the rubber band might slip off or tear apart.That's a quick fix for an otherwise decent product. Again, I can't say for sure it works, but my vet recommended it, and a friend who is also a vet said they do the job, too.The cats seem better with one another, but its certainly not an entirely peaceful co-existence.

NEVER AGAIN!! In my attempt to help my twin boys, Panther and Puma, from suddenly fighting after over two years of only peace and love, I feel that this product could have killed my precious Puma.I had purchased one of these and put it on my Panther, as he was the one who had become the aggressor. I asked the vet to show me how to put it on, and she showed me to have it loose enough to put two fingers inside the collar while on the cat. When I got home from the vet, it wasn't even 10 minutes until he had it off. When I found it, it was obvious that somehow he chewed through it.I ordered two more and put one on each cat last night. I put it a little tighter, leaving room for one finger in the collar, hoping that this would not let them be able to get it off. I checked numerous times to make sure it wasn't too tight, that they didn't have any difficulties breathing. I awoke this morning hearing a scratching noise on the floor beside my bed. I turned on the lights to see Puma being choked by the collar. It was stuck very tight inside his mouth with his mouth wide-open and the back of it still behind his ears. We have wood floors and there was a puddle of saliva mixed with blood in front of him. I grabbed him and tried to tear the collar off. I could not get it to break apart, despite pulling on it very hard. With my boy in obvious danger, I grabbed him and ran to where we keep the scissors and cut it off. He had blood all around his mouth and for the next 20 minutes, he licked his paws. I could not tell him how sorry I was to put him in this dangerous situation. I'm just so glad that it happened right beside me while I was home! Had I not been home, I fear that I may have come home to a deceased little boy.I later picked up the cut collar to show my wife that it should break apart and I had to pull really hard to get the release to come apart. I know that it has to be difficult for the manufacturer to make it so that it doesn't fall apart easily but come apart in an emergency, but I feel that it's too difficult to release.Just glad I still have my boys alive and I will never put another collar on them.
