CatCursor

Like it says on the tin:

A simple program that makes your cursor leaves a trail of cat-related particles whenever it moves.

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.

It might also flat out not work on MacOS because I had no way of testing it.
