I was running a bath, and he was sitting slumbering in the sink. When I realized that the water was getting a little cold, I stood up and turned on the hot water tap.
I slipped and fell down.
I woke up, thanks to someone hitting my face. It turns out that I'd been knocked out and almost drowned. But my little kitty had start 'meow'ing and hitting my face with his paws to wake me up. Thanks kitty!
