CatCursor

Like it says on the tin:

A simple program that makes your cursor leaves a trail of cat-related particles in various situations (for now, this only works when you perform mouse presses and moving the mouse).

I will figure out how to make more cat stuff happens around your cursor, and more uniformly across different platforms later (hopefully).

P.S.:
Since this thing might try to track your mouse and keyboard, it might be flagged as malware.

MacOS version indefinitely pending and broken because I have no way to debug the problems with its platform specific code for Mac devices.
