Oh, you'll know. The car (Prius or any car) will start but will be super loud as the exhaust is no longer going through the muffler/tailpipe.
Generally, the catalysts are not stolen to be used on another car. It usually gets sold for peanuts to a recycler who will recover the precious metals. Someone with a cordless sawzall can remove the catalytic converter in about a minute.
These things seem to go in waves as a group of thieves will hit an area until there's too much attention and they move on to another local. The part that's odd is the Prius angle. The Prius has a tiny catalytic converter. More or less, the bigger the engine the bigger the catalyst. They should be hitting F-150s. Maybe a guy learned how to get the catalyst out of a Prius easily and is just doing what he know.
I have a Prius and will not lose sleep over this not-the-end-of-the-world sort of crime.
This article has some ideas.
