Question I think my cat may be clogged

The car started to run real bad. Almost to the point of stalling. It was almost like when a fuel pump goes out. You know bogging and then coming back a bit then bogging again?
Well anyway I pulled over and noticed smoke coming from the back of the engine. So I looked underneath and the cat was smoking like crazy! So I assume it's clogged. I've honestly never had a cat go bad on a car before (my 94 doesn't have one anymore). Does this sound like the case? I'm gonna pull it off when she cools down, and see what I can find.
Any input would be great.

Yeah possibly remove it and hollow it out/"gut it" and if you have/want to, just buy an aftermarket converter. Random Tech seems to be the leader in the High Flow Cat-conveter business. Goodluck

Thanks,
I just finished eliminating that as a possible cause I hope that was it. It sounds a lot better now. Not all tinny like I thought it would.
