A rat is a vast mouse that specializes in hacking into computers and clearing their hard drives. Rats are known to live in all sewer systems around the world, and most are involved in a sinister secret society which controls all activity on planet Earth. A variant of rats, called flying rats, are also known as cats, though they are occasionally confused with bats.

There's no need to yell, you know. I can hear you just fine.
I already heard you! Shut up!
