This seems to me just the sort of cat that would be found sitting on the back of a witch's broomstick, or tucked in the corner of her room watching her stir up a potion in a cauldron!
This cat wouldn't be out of place cut from black paper in a Halloween display - but could look equally good in a softer colour and with a cute face drawn on. It comes in various sizes.
