Geez Debbie, just reading this gave me a heart attack! My cats don't wear collars because of this. I know of one that died at the shelter before anyone realized his jaw was hung in the collar.
I know it probably wasn't fun for you but I'm glad to hear that cat daddy Terry got so upset!
I think Moosmom is on to something with the Victoria Secret knife weilding bra. There may be a fortune in the future for such a thing!
