Here's why it works:
* Cats and Pigeons: Cats are natural predators of pigeons. Imagine a cat suddenly appearing among a flock of pigeons. It would create chaos and panic, causing the pigeons to scatter and squawk.
* The Analogy: The idiom uses this image to symbolize a person or situation that disrupts a peaceful or stable environment, leading to conflict and disorder.
Here are some examples of how the phrase is used:
* "The CEO's decision to downsize the company put the cat among the pigeons, with employees fearing for their jobs."
* "The politician's controversial statement about immigration put the cat among the pigeons, sparking a heated debate."
Remember: The phrase is often used in a humorous or ironic way, implying that the person or situation causing trouble might not be aware of the consequences.
