How many catalytic converters are there ?
One, unless you're in south america....then none.
There's a dozen engines listed for the '01 Jetta. The 2.8L V6 looks to have three converters. Two small ones in the down tubes and a larger third one further back. - What engine do you have and why do you want to know?

What's an o2 sensor? and did you know that there are valuable metal in a catalytic converter and people steal them? Someone told me this a while back about how one day he got in his truck and literally got the crap scared out of himself when he started the engine and not cat conversation. And well I could tell you more about this but I'm busy.
