The meow seems to be a demand for a service, made when the cat wants to be fed, wants a door opened or just when he wants attention. The interesting thing about the meow sound is that it seems to be almost exclusively reserved for human beings. Very young kittens may occasionally make the meow sound to their mother, but after they are grown, cats virtually never meow to other cats or to dogs or other pets. Dogs apparently understand that the meow sound has nothing to do with them, or they are unwilling to provide the service the cat is demanding of them, since they seldom seem stirred to move toward a meowing cat.
