I struggled so hard to get this around my cats small neck making sure it was tight enough but loose enough (the collar you push through the buckle doesn't slide easily at all). While doing so I rubbed most, if not all, of the powder off. Does this render the collar ineffective?
Answer by ChewyFeb 22, 2018
The powder that flakes off the collar when it is being stretched and applied is a normal occurrence and is how the collar operates. The pheromones are impregnated into the collar itself for a sustained release and the collar will still work for your pet and will not make the collar less effective.

Is it okay to have this collar on the cat along with a flea collar at same time?
Answer by ChewySep 06, 2017
You can use this Calming Collar along with a flea collar. We advise keeping an eye on the area for signs of irritation or any discomfort from your pet.

My cats like to groom each other. Is this toxic?
Answer by ChewyAug 23, 2017
This collar is completely safe for normal grooming.

Are you supposed to remove the powder from the collar when you first open it?
Answer by ChewyDec 01, 2022
This collar has no specific handling instructions and does not need to be wiped off.

Worked for temporary travel anxiety

She was having a lot of anxiety after some holiday travel and would not leave me alone at all. On top of that, she would try to get my attention by nipping at me. After the collar, she still needed me a lot but was definitely calmer about it. She stopped nipping at me and meowing at me at all moments of the day. It helped me naturally get her back to feeling comfortable with her surroundings and I could actually sit at my desk and work without having to settle her first and block her into another area of the house. It didn't immediately send her back to normal, but I wouldn't have wanted something that did or I would feel like I drugged her. She was still playful and needy, but it just made it way more manageable. Also, she's an indoor cat so she's not used to a collar. She adjusted just fine.

Calms cat with IBD

I really like these collars. I have a cat with IBD and these help reduce his anxiety and IBD flare ups. However, the three pack has doubled in price since April 2022. It's really disappointing and I've found other alternatives for my cat.

New Dog Integration

These are definitely working. One of my cats was diagnosed with stress induced urinary issues two days before we were supposed to pick up our newly adopted husky mix. He recovered from the episode but obviously I was concerned. We got the collars yesterday, and my cats have been assorted puddles of goo and love. They're markedly braver about walking past the dog, coming out of their safe rooms, and are being kinder to each other. No issues with them falling off.

Works Great

This collar has helped my year old cat that has awful anxiety and is very skittish. Although my cat doesn’t have any behavioral issues, the collar has helped him be more outgoing towards people as well as hide less. It’s amazing to see my cat warm up to me and be himself.

So grateful for this product!!!

My 8 year old cat has always had a lot of anxiety. We recently got a new kitten and she went into anxiety overload. She hid under the bed all the time and she stopped laying on her back to nap. She was so tense and jumpy, she seemed miserable. A couple weeks into wearing this collar, she's up between 5:30-6am every morning running around the house playing with the kitten. She lays on her back and purrs and rolls around. She's done a complete 180! I'm so grateful for this collar.. it really hurt my heart to see her so upset. She's always had anxiety, like I said. It hasn't cured that 100% but like I said, 180 from a couple weeks ago. She's comfortable and secure and she's bonded with her new kitten sister. I cannot recommend this collar enough. I've got it on autoship now.

Best one Available

My Kelly cat is a nervous wreck, constantly full of anxiety and dread about every sound, sight and motion. This Sentry collar had an amazing effect. It calmed her into being comfortable and soothed. Kelly was so much more enjoyable to be around. I have tried other calming collars but have not found one as effective. The Sentry is definitely worth paying for. I only wish it last longer, it only lasts about 3 weeks for my cat.

Absolutely the best calming product so far

We rescued our anxious kitty 6 yr ago. You would think after 6 years her anxiety levels would have lessened especially considering she is pampered and is in a loving home blah blah blah.. but nope.. she runs everytime someone comes over, won't let us pick her up and hold her without trying to run... I have used calming cat defusers which are not cheap. Nothing worked. I was at my wits end, and was about to have the vet put her on anxiety meds. I then decided to try this product first. Ohhhh my goodness.. what a huge difference!!!!! She still runs when someone pulls car into drive way, but this time she will come back and Actually be ok with being in the same room with the guest who is over. That is not normal for my cat. I am beyond pleased with this product!! I will keep on buying this product for sure!!

A much happier kitty

My cat Princess had always been the terror of the house. She'd stalk other cats, attack them and if I'd pet her more than a few minutes she'd lash out at me. Our vet suggested these collars. They have been amazing! She is much more calm when around other cats and just lets them pass by. She hasn't been lashing out and will sit beside me without being aggressive. At night she has even been sleeping on the bed with me. I'm going to continue ordering these collars for her since they are working so well.

This works

We got a kitten and one of our resident cats was NOT happy. She was getting fresh with everyone (feline & human). I put this on her and within an hour she was climbing up in my lap giving head bumps. The kitten is still sequestered in her own room, but was crying loudly to come out. I went in to play with her to keep her busy and stop the crying, but instead she climbed up to my chest where she could smell the scent of the collar from my other cat just being on me/my clothes. Kitten stopped crying and curled up in her little bed and was mellow! I couldn't believe how quickly it worked. I had some pieces left over from a year ago (that I cut off collars that were too long). I kept them stored in the (opened) foil pouch and sealed in a ziplock bag. Those pieces kept their scent and seemed to still be effective. I keep a piece in my shirt pocket when I snuggle my kitties. But I think once it's being used, it lasts shorter than 30 days.

This is the best

This really works great for my scaredy-cat!! She so nervous and scared of everything. With this collar she like my other cat. Out watching the rain from a thunderstorm or out to greet new people when. They come over. The self harm of licking one spot bald stopped and the hair chewing/pulling also stopped. This thing is the best.
