My mom's cat, Fritty, would always wait for me to get up and start getting ready for school, for, beign a gray cat in a house that's full of gray carpet, when the lights are off in the morning (as they usually are, since I was always the first up) you could NEVER see him.
At least, not until he was latched to your ankle biting and tearing off your flesh.

But he really was a violent kitty, though that was because he was a bottle baby. And he dun wrestle, he fights... I have scars all along my arms because we played. But boy, he sure enjoyed it. o.O'

Hope your hand gets better soon, though it seems like things are better now ^_^
