The Barrison Sisters used the term in a risque Vaudeville act in the late 19th century: In their most famous act, the sisters would dance, raising their skirts slightly above their knees, and ask the audience, "Would you like to see my pussy?" When they had coaxed the audience into an enthusiastic response, they would raise up their skirts, revealing that each sister was wearing underwear of their own manufacture that had a live kitten secured over the crotch.
