We recently discovered that some mice had invaded our house. The cats being not much help (one of them is an old slob, the other one’s just stupid), we put up mouse traps. The mice that get caught get fed to the cats.
The older cat has developed a new set of reflexes. When it enters the house, it will first check out the mouse trap and only then head for its bowl. When the trap goes snap! the cat will be there right away.
Eh.
