yeah cats can get strangled on their collars pretty easily so they now have these onces called Beastie Bands which are made of a sponge type of material which stretches plus the whole thing is held together by velcro. When I adopted Trinity and Neo they had these on from their former owner and they looked good but I couldn't keep them on the kitties, they would eventually end up losing them somewhere so I quit using them and got the kitties microchipped. Now that I have lost Trinity (gone a month now :-() I kinda wish I had kept the collar on tho. Another problem was they both love to drink from the faucet in the sink which I turn on for them and this was making the collars wet.
