Neko would follow the mouse pointer around. 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.

Schrodinger's Cat will follow your pointer. When it catches the pointer it will turn into a box and then enter. There is a 50/50 chance of weather that cat will be awake or asleep after pointer is moved off the box. This is designed to be a simple amusing way to demonstrate Schrodinger's Cat thought experiment.

Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects, resulting in a contradiction with common sense.
