Where Does ‘Let the Cat Out of the Bag’ Come From? 

Some sources say that the phrase ‘let the cat out of the bag’ comes from the Middle Ages when people would go to purchase a pig, and the vendor would sneak a cat into the bag instead, which was cheaper than a pig.

The buyer wouldn’t find out they had a cat instead of a pig until they got home and literally let the cat out of the bag. Once they did that, they realized they’d been scammed.

However, other sources say that this would have been impossible because of the difference in weight between a cat and a pig.

The phrase has been known to allude to a deceitful purchase in the Dutch and German versions of the phrase, which translates to:

To buy a cat in a bag.

Another theory states that the ‘cat’ refers to a whip made from nine intertwined cords that were used as a form of punishment by the British Royal Navy and in prisons. It was called a cat because the marks left by it resembled the scratches you might get from a cat.
