I saw this a few weeks ago......Intending to save you--and your pet--the "embarrassment of a bare behind," e-tailer Twinkle Tush manufactures jewelry to bedazzle a cat's anus. The gems come only in blue, made to hang from your cat's tail. Twinkle Tush is available for purchase at $5.99 (plus a standard $1 ship fee) through Cat Crib, an online marketplace for cat hammocks.
