Have you visually checked it? I had a plastic grocery bag wrapped around mine for a week that I did not notice until I jacked the car up and checked it out. By then, it was almost completely melted off.

May be melting down. Bang on it (when it's cold) & see if you hear chunks bouncing around inside the cat. Depending on the year of the car, may be under warranty. It was 50,000 awhile ago, recent couple years they (Feds) changed new car to 80,000 for cats. You should be able to get that info from the dealer. But call a couple private shops too, dealers don't like to work for 1/2 normal rate. That's all they get (from the manufacturer, not you) for warranty stuff.

That's a good answer too, I can't count how many times I've seen that on customers cars.

The usual reason for a "rotten egg" sulfur smell from a catalytic convertor is a rich fuel mixture. That's why following an underpowered car up a long hill tends to make a sticnk. Cats operate best on very lean fuel mixtures. If you have access to an infrared exhaust analyzer, hook up and check the CO reading. Anything above about 1.5% CO can cause a stench. Correcting the rich mix depends on what she's driving.
