If it's 100,000 miles old, it would be a good idea. A bad O2 sensor can make the car run too rich and shorten the life of the cat.
You can get generic O2 sensors at Autozone for $60 or so.

Since the most probable cause of premature catalyst failure is an over rich condition, it is possible that you need an O2 sensor replacement. However, this can be tested and verified by a competent mechanic since there are other conditions that can result in an over rich condition.
