It's all about the yardstick we use for measuring intelligence, isn't it? For years, my rescue cat has had an annoying habit of gently plucking at my clothes with her claws for no apparent reason. Then one day I had an epiphany. I discovered that scritching the top of her head made her stop plucking my clothes. Now she gets head scritches whenever she wants. So from her perspective I am thoroughly stupid, yet capable of learning simple tricks given enough repetition and reinforcement.
