Could be as simple as a sensor. If there are other engine codes, that could mean a bigger issue. The obvious first steps are to check if the cat is actually still there or if wires to the sensors are damaged.
Catalytic converters can last a long time unless combustion issues or other serious engine problems are ignored. TBH, catalytic converter codes are generally just a symptom of something else. So, do as detailed of an inspection as you can for any wiring damage or leaks. If you have any leaks, try your best to identify the kind of fluid it is. Maybe you can get a hint about what else is going on.
Combustion control is horrendously complex, so it could be any number of things from bad spark plugs to a malfunction in the EGR system. Any information you can gather about the problem now may save you some time and money later.
(I dunno if you know anything about cars, but I just covered the basics, just in case.)
