For the last time, leaping at the window will not make it open. You do not have magical superpowers like that. And when it's 41 degrees outside, mommy is not going to open the window for you. One day, I will build a house with nice, wide, warm windowsills built just for cats, and then you can lounge all you want without having to rely on my and my thumbs to open the window. In the meantime, quit with the leaping at the unopen window before you hurt yourself, ok?
