  1. To “let the cat out of the bag” originates from another english colloquialism, “pig in a poke”, which has the same meaning as the German “cat in a sack”. It was seemingly an international scam, where vendors would sell a piglet/fish/rabbit in a sack, and by the time the purchaser finished shopping and opened the bag, they would find a dead cat instead of what they thought they were buying. Interestingly, like many idioms, this is a saying in dozens of languages and cultures.
