First off-- let's say, it's not calming to your kitty nor you (nor your breeder) when you use a calming collar and it nearly kills your kitty 
Yesterday, one of my kitten owners put the Sentry Calming Collar on her F2 Savannah. Looking at the package, it clearly states that it is for cats and is a breakaway collar and although you cannot see it well in pictures, I am told there is a delineation on the collar which make it appear as though that is the case.
My owner heard one of her Sphynxes hissing and throwing a huge fit in the other room and hurried in to see what was going on. She found her beautiful F2 Savannah limp on the floor, the collar stuck in her mouth and drool all over the place. Shortly after she removed the collar, Zoe-- our girl-- regained consciousness, but she exhibited neurological symptoms from the lack of oxygen the rest of that day and finally today-- 24 hours later-- appears to be doing okay.
After the owner brought this situation up on Facebook-- MANY other cat owners said they had the same situation in which they had applied the collar and somehow, the cat managed to get it caught in their mouth. My only assumption is that the collar is smooth looking and the cats are managing to claw it just enough to open it a bit further and then they hook it and panic-- which is when the owners tend to intercede. The situation yesterday, however, came close to deadly and without the Sphynx's hissy fit, I think my girl would probably be at the Bridge today.
PLEASE do not risk your cat/kittens and DO NOT use this collar. There are other calming products on the market. Please do not buy this Sentry Calming Collar for cats
IT IS NOT A BREAKAWAY COLLAR-- or better put-- their breakaway system DOES NOT WORK.
