Ok, so my cat jumps up onto the counter from an autimon (how ever you spell it); so I go and slap it for being on the counter. It jumps down from the counter into my iBook and my iBook tumbles backwards onto the floor from about a foot and a half up. Should I be worried? The HDD does have the one feature where it removes the head if it notices any weird movements. I'm just really nervous about my iBook.
