From the developer:
Neko 2014 is an animation that will follow your mouse pointer. When cat caught up with the pointer, it would stare at the screen for a few seconds, scratch an itch on its body, yawn, and fall asleep until the pointer was disturbed. In windowed mode, cat would stop at window boundaries and scratch at the edge of the window.
