My Cat Princess has several meow sounds that she uses to communicate with me, for instance when she comes down stairs from her nap she announces her self clearly saying here I am. If she wants something very intently,she uses a very high pitch tone. And when she is upset with me, she has a meow that starts then cuts off halfway then finishes then I know she is telling me off. Sometimes she sounds like a bird. One of the funniest, she says brow wow wow that's when she wants to be noticed.
