Meowing is a language cats invented purely to communicate with people. Adult cats don't meow at each other - between themselves they communicate through body language, scent, and vocalizations like hissing, growling, or purring. Meowing is a sound reserved for an owner - a signal that a cat needs something and has learned that this particular sound gets a response.
