I have a hand-me-down cat from my daughter. He ate a roll of Christmas ribbon before I got him. Guess he started playing with it and swallowed a piece. Couldn't get it out and just kept swallowing more. She had to pull it out foot by foot. Good thing she found him before the last of it went down. Not a pleasant task for either human or cat. Moral--keep unsafe things out of their reach or watch them very closely.
