So he had about twelves inches of the cobweb/poo mixture following him around wherever he went. We all started freaking out immediately, and then the cat realized what was going on. It started chasing the string around. Like how a cat will chase his tail in a circle, same thing. Except he was chasing poo/web. It was simultaneously funniest and grossest thing I've seen in a LONG time.
It was gross while it was happening, and extremely funny in retrospect. What a great party.
