CNN Story on "This is what your cat is really trying to say"
Cats and their humans develop a secret language of meows. Cats don't really meow to communicate with other cats, Bradshaw said, which in itself is a pretty surprising little cat-fact. But in his observations of feral cats, he said, "you get a meow about once every hundred hours. They're very silent." And yet domesticated cats, as you know if you've got one, will often meow their little heads off, all day (and sometimes night!) long. "People think of it as an absolutely classic cat behavior ... but it's something they've learned to do to get our attention," Bradshaw said. "It's really something they've adopted as a way of communicating with humans."
I've known a lot of cats that meow just for us. Our cat Caesar meows so loud some days it wakes us up (of course he rattled door handles too). His intentions are to get his food.
