We have a 5 yr old black cat name Pyewacket. This is the name of the Siamese cat (familiar) who lives with Gillian Holroyd (played by Kim Novak)
in '58 "Bell, Book and Candle).
The supposed first use was: "Pyewacket (familiar spirit), a familiar spirit, reported by an alleged witch in 1644" according to
