Default How can you tell if a catalytic converter is bad?

I need a new cat and Im buying a used oem one. is there anyway I can check to see if its bad? What do I need to look for? He said he had check engine light but it was becuase of his O2 sensor..

if you hold it up to a light and rotate it, you should be able to see a pinhole at EVERY angle.

Lack of performance, bad gas mileage, smells like crap, hear a rattling noise in some cases.
