How a cat 'speaks' is quiet remarkable. They don't speak phrases to express affection, outrage, hunger, loneliness, boredom, confusion, happiness and fear in their natural frequency range, which would be inaudible to humans, but at a much lower frequency that humans can hear. Some researchers believe they may have learned we can't hear them in their natural range and have adapted so they can relate to us on our terms.
