Meowing is an interesting vocalization in that adult cats don’t actually meow at each other, just at people. Kittens meow to let their mother know they’re cold or hungry, but once they get a bit older, cats no longer meow to other cats. But they continue to meow to people throughout their lives, probably because meowing gets people to do what they want.
