The expression "live like a cat and dog" is an idiomatic phrase that describes a situation where two people, typically a couple or roommates, have a tense, hostile, or unfriendly relationship. This phrase is not meant to be taken literally, as cats and dogs are often depicted as natural enemies due to their differing behaviors and instincts.

It serves as a warning or a description of an unsustainable living situation where peace and mutual respect are absent.
