Who's training whom?

Cats learn by observation, imitation, trial and error just as humans do. Stories abound which describe cats turning doorknobs to open doors, ringing doorbells, opening cupboards, turning off lights, and even using the toilet, solely by observing the owner perform these activities. Many feline behaviorists, as well as child psychologists, seem to agree that the intelligence of an adult cat equals that of a 2 to 3 year old child. We know how clever and manipulative children of this age are, is it any wonder that cats are better at training their owners than the owners are at training them?
