There are lots of colourful idioms about animals in English, and although they might sound strange or funny to a foreigner, they are completely natural to a native speaker. This great expression means to disclose a secret, usually by mistake. People often say 'don't let the cat out of the bag' when they are sharing a secret.

The expression let the cat out of the bag probably comes from the days when people used to buy animals at markets. Sometimes, a market trader would put a cat in his bag and pretend it was a pig to cheat the customer! So, if someone let the cat out of the bag, the fraud or secret would be revealed.
