THE ORIGIN OF PYEWACKET

Pyewacket was one of the familiar spirits of a witch detected by the "witchfinder general" Matthew Hopkins in March 1644 in the town of Manningtree, Essex, England. Hopkins claimed he spied on the witches as they held their meeting close by his house, and heard them mention the name of a local woman. She was arrested and deprived of sleep for four nights, at the end of which she confessed and called out the names of her familiars, describing the forms in which they should appear. They were:

• Holt, "who came in like a white kittling"
• Jarmara, "who came in like a fat Spaniel without any legs at all"
• Vinegar Tom, "who was like a long-legg'd greyhound, with a head like an Oxe"
• Sacke and Sugar, "like a black Rabbet"
• Newes, "like a Polecat"
• Elemanzer, Pyewacket, Peck in the Crown, Grizzel, Greedigut, described as imps

Hopkins claims he and nine other witnesses saw the first five of these, which appeared in the forms described by the witch. Only the first of these was in the form of a cat; the next two were dogs, and the others were a black rabbit and a polecat – so Pyewacket was, presumably, not a cat's name. As for the other familiars, Hopkins says only that they were such that "no mortall could invent." The incident is described in Hopkins's pamphlet "The Discovery of Witches" (1647).

In the Hollywood film Bell, Book and Candle (1958) Pyewacket is the name of the cat/familiar of Gillian Holroyd (Kim Novak. 
The original 1950 play starred Rex Harrison, his then wife Lilli Palmer, Jean Adair, and Larry Gates.

It is extremely popular among the Siamese Cat Lovers of the world. In 1956 during the popular craze over the Siamese breed Hollywood decided to cash in.

Cast with the hottest actress of the day, Kim Novak and James Stewart the first ever Siamese in film, Pyewacket would be stealing the show in the film Bell Book and Candle.

Kim Novak plays Gillian Holroyd, a Greenwich Village Witch who wants "something nice for Christmas" which her cat, Pyewacket brings her a mortal...

Jimmy Stewart plays Shep, the mortal that Gillian falls in love with and with the help of Pyewacket her magical familiar, she gets her man!
