My cat nutterbutterbuttercup- thinks she is a vulture, constantly stalking things that move(usually people), will try to run as fast as she can throughout the house, and will try to basically drift corners, and she'll run into a wall and literally climb a yard up it and then jump off...
And then my other cat, oatmeal, is the fastest cat in the world, i swear...And her meows sound like a divebombing plane...Middle of the night, you hear MEEEEOOOOOOW
