Grimalkin

A grimalkin (also called a greymalkin) is an archaic term for a cat. The term stems from "grey" (the colour) plus "malkin", an archaic term with several meanings (a cat, a low class woman, a weakling, a mop or a name) derived from a hypocoristic form of the female name Maud. Scottish legend makes reference to the grimalkin as a faery cat that dwells in the highlands.
