I heard somewhere that a cat only meows because they hear humans making noises at each other and want to join in.
It doesn't actually mean anything.
So I take immense satisfaction when I get to pass a meow back and forth between my cat because we are effectively just going "Wah❤" at each other.
Also, despite being two different species we have effectively bridged a gap in communication even if the words don't mean anything. We learn from each other.
Even if we don't use actual words, a loud sound can mean: "I'm hungry," "I want attention," or simply "I am here," from the cat.
And theres something so special about that to me. We care about each other so much we want to do the things the other does to reach a common understanding.
