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.

Are you supposed to remove the powder from the collar when you first open it?

Answer by ChewyMar 10, 2024
This collar has no specific handling instructions and does not need to be wiped off.

I put this on my kitten. He tried biting it to take it off, is the powered toxic to the kitten if ingested?

Answer by ChewySep 30, 2018
The powder isn't harmful to animals.

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.

Not sure that I like this collar

I put one on my cat and it was fine for the first couple of hours but then my cat started scratching his head and shaking his head, kept sticking out his tongue

I put one on my cat and it was fine for the first couple of hours but then my cat started scratching his head and shaking his head, kept sticking out his tongue like something was in his mouth . This did t start until I put the calming collar on. I took it off along with his regular collar and I think he is doing a tad better with the scratching, head shaking , tongue. Not super impressed

This is the first time I tried a calming collar when family was coming to stay for awhile (including their dog). Usually I have to sedate Lucky, my cat, or he gets so anxious he pees on my bed. Not this time. The collar alone kept him calm. Next time family comes to town I'll be ready with another collar!

This worked

We put these on three cats to move them across states and introduce them to each other. The collars were very helpful in keeping the peace

Cat collar was perfect

She enjoys outdoors. She won't put on a harness so this works for her. The elastic in the collar keeps her safe if she pulling her leash.

Bunny's Treats

My Manx is picky, but she loves these. They do calm her. Between 4th of July Fireworks, Thunderstorms and Dollywood Amusement Park, she's been stressed out

Effective!

Occasionally my cat goes through phases where she needs these! Within 24 hours, she goes from a cat you don’t dare touch unless she invited you to a relaxed kitty

My cats are calmer.

I bought this item also with the plug. They work well together.

Used to buy this when it was cheaper, does not work as well now

This used to help with my cat's anxiety back when it was 7 bucks. Now, not so much. Not sure if something has changed about it but I'll probably cancel my autoship

Great collars!!

One of our cats was constantly "phantom" spraying, so I decided to use these collars before it turned into actual spraying. The collars have done an excellent job

One of our cats was constantly "phantom" spraying, so I decided to use these collars before it turned into actual spraying. The collars have done an excellent job of curtailing this behavior. I also used it on one of our cats that is very skittish/fearful of people, and it seems to have helped with that issues also.
