This phrase is like a boss yelling at a whole room of lazy workers, telling them to stop chatting and do their job before the cat gets more annoyed than a kid who spilled soda on a math test.

You're basically telling everyone to be quiet and do what you say, or the cat will turn on you like it did to that intern who forgot to bring snacks.

This phrase is like throwing a tantrum in front of everyone, telling them to be quiet and do what you say before the cat decides to take over the office.
