Mouser
/ˈmaʊ.zɚ/noun
A cat or other animal that catches mice; also a person or thing that hunts mice.
Did you know?The word is built from the same Old English root as *mouse*, so a *mouser* is literally “one who does mouse-hunting,” not a mystical title—but it still carries the aura of a household guardian against vermin.
