Rats are disgusting little varmints. They are dirty, rodent scavengers who carry all manner of communicable diseases. Some may regard rats as wingless bats, which are equally foul, but this is something of a misnomer, since the two are not truly related to one another, despite how their names rhyme.
Rats tend to thrive in dark, enclosed places where it is warm. As such, they can frequently be found nesting in sewers, subway channels and other such avenues while they conspire and scheme to take over the world.
One who is tasked with tracking down and capturing the miserable little cretins are called Rat catchers - a thankless job to be sure, but one they every catcher seems to take great pride in.
