Tigger once ate some yarn and we didn't find out until one day he walked in the livingroom with poop still hanging onto his butt. I called my mom over and when she pulled the poop off, a decent amount of yarn proceeded to come out of his butt. I wish that I had a working video camera on me that day because it would of been a good one for AFV. Tigger was fine after that. And for the rest of his life, he didn't eat any more yarn.
