Too much unburnt fuel entering exhaust stream

^^exactly. You could also have issues with the oxygen sensor(s) which can cause too much fuel in the air flow and result in the same issue with the catalytic converter. Additionally, if you have ever seen your check engine light on and your cruise light flashing, it was an indicator that something bad could happen to your CC.
