when the cat goes bad alot of times either the cat or the pipe directly before it will heat up red hot.. A bad alternator that is overcharging can also smell like rotten eggs

also if you either ran over a critter and knocked parts of it onto the cat or a critter crawled onto your exhaust and died , that can smell wonderful also, as will plastic that landed on the cat
