The idiomatic expression "cat in a bag" originates from an old English proverb that cautions against making assumptions or judgments without sufficient evidence. This phrase is rooted in the unpredictability and potential danger of dealing with unknowns, symbolized by the mysterious contents of a bag containing an unseen cat.

Historically, the expression has been used to advise individuals not to rush into decisions or agreements without fully understanding the situation at hand. The analogy compares the uncertainty of what lies within the bag to the risks involved in committing oneself to something without thorough investigation.
