I know I'm lucky, and both of them were just so funny when it happened! With Marlee, I had just walked in the door from class and she was waiting at the foot of the stairs just inside to greet me like usual. She sorta leaned over and spit something out. I leaned down to look, and there was a little toothy!
And with Milo, we were sitting downstairs watching TV and he was sorta scratching the side of his face and meowed real loud. Sorta startled me of course, so I look at him and his tooth just falls out! He kinda looked at me then ran off to play.
