Generally a Cat is good for about 75k, or so I'm told. after that, it's a crap shoot.
Odds are if there are no problems with mileage or temps, they're still doing their jobs. I just make sure I mention them so you won't be surprized when they DO need replacing.
A good muffler man can check them, and an even better one does it for free. If you need one, I got a guy down here that I'd leave my wallet on the front seat while he works on it; he's that honest.
some pointers... If the car has that "rotten egg smell" on start-up OR an otherwise sound engine bucks or hiccups on heavy acceleration, it is probably the cat.
