Origin: The usual explanation is a market trick told across Europe: a buyer paid for a piglet in a closed sack and found at home that it was a cat. English "buy a pig in a poke" and "let the cat out of the bag" come from the same picture, and German has die Katze im Sack kaufen. The trick is a traditional story rather than a documented practice.
