I had a cat chew off and eat the end of a bra once. Couldn't figure out why I couldn't fasten it - it kept slipping through my fingers. Then I found out exactly what happened when he threw it up.... :P We'd have to make sure our shoe strings were neatly tucked into our shoes too - or he'd mow them off. He was a stinker!
I'm glad it all "came out" ok! :D
