Okay, that's my calling - ridding the world of the rat - put it on a pedestal like smallpox, keep it in the lab, etc. But, the fields and cities are out of bounds. (Mice too - coz they can evolve into rats super fast if rats are displaced (I think))
The solution - autonomous robots that look like rats, that roam, have sensors (odour, hi-res cameras, audio) and will root out and destroy the rats they encounter.
