Put me down for "Scientific method fail." Kitties do not process information the same way that dogs do. But a smart cat can figure out cause and effect all on their own if they want. Case in point my cat Mac who taught himself how to fetch based on his observations of "If I bring the toy back to Mom, she'll make it come alive again."

I say "smart" cats because I have known some stupid ones in my time. Like the kitty I had who meowed oh so sadly about how she was LOCKED IN THE BATHROOM WOE... and totally ignored the fact that there was an open door right behind her.
