Put a cucumber behind a cat and watch it flip out in terror.
Place a flower on a cat’s nose and see it react in bug-eyed shock.
But try to play a version of The Shell Game with a cat? Hide a ball under one of a trio of containers and ask him to identity the container that is hiding said ball?
As you can see here with a feline named Hamlet, he’ll play along… he’ll even choose the correct container… he just won’t seem to be very impressed by the whole thing.
