Most people want to think that they are in control of their pets. However, a study by Karen McComb at the University of Sussex found that cat owners are controlled by their cats. Cat owners probably won’t have too much trouble believing this. Cats make a fairly loud noise by mixing a purr with a cry. The sound seems to be less annoying to humans than straight meowing. Using this sound, cats tell humans when they want to eat and when they want the door opened. The purr part of the sound keeps humans from becoming too annoyed, so the cat gets exactly what he or she wants.
