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.

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.

How to do secure the collar? The bucket doesn’t clip or anything.
Answer by ChewyOct 14, 2021
The open end of the collar slides through the opposite end and through the clasp. The friction between the collar ends will keep it from sliding freely.

Did not work with my cat

I bought the collar for my cat since I was leaving for vacation, I was trying to make her calm when staying with my friend and her cat but it did not work at all, I even put the collar days before but there was no change at all. She was nervous and irritable even easier than before.

The opposite of calm, my cat absolutely freaked out from this collar. The smell was even too fragrant for me; I cannot imagine it is not also a skin irritant. She was agitated for hours so I could not cut it off. Luckily she got it off her neck when I wasn't looking without hurting herself. Absolutely do not recommend. This product should be pulled.

Recommend 10/10

I have four cats and three collars help them relax when they’re all awake and ready to play. These collars are easy to put on and take off, they smell good, and they definitely calm my chaotic cats.

Lavender?! what a joke.

It's a toss up who hated it more, me or the cat. He couldn't get it off fast enough, nor I seal this awful thing back up in the can. I got scolded by my vet for not getting Feliway.

used to be GREAT now they aren’t

These used to be amazing. But of course you had to mess with a perfect product and “make it better”. Now it doesn’t stay on at all. Please change the buckle back to the old way so it can stay on the kitties whom so very much need this.

Reduces Kitty's Unpredictable Behavior

Our one kitty arrived to us with some health issues that cause her to be defensive (aggressive) and territorial. We have had her 10 years and as she has aged, she has not mellowed. We tried the Calming Collar and have found a difference: Fewer unpredictable bouts of aggression and sometimes she is nice. The collar has a pleasant scent, too. I will continue to purchase this for her (us)!

Calming collar

I can smell the scent from the collar, but it hasn't calm him down, only been a few weeks. Let's wait and see, I check his neck everyday, no sign of irritation. He is a feral cat.

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.

Will not stay on!

Bought this collar multiple times hoping it was an uncommon issue, but they never stay on my cats. I have a lazy inactive cat and it falls off her constantly. Wasted much money.

Artificially Scented - READ THIS

This product is heavily scented. I held it up to my cat to sniff and he immediately squinted his eyes and backed away. I tried to approach him again with it and he ran from me. I really wanted to love this, but I don’t want to hurt my baby. Scented items can harm cats in a lot of ways and I just don’t want to risk it. I recommend searching for an alternative to this product that is not scented (however they did not say anywhere on the item description that it was scented…) I’m wondering if this even calms cats or is just making them super sick to the point where they don’t feel good enough to act like their normal self. I couldn’t imagine having something with this strong of a scent around my neck 24/7, and my nose isn’t even as good as cats noses!
