“Though most animals are gun-shy, a wild puma kept at a laboratory in Moscow, Russia, deliberately fires a cannon to signify that it is hungry. Laboratory workers trained the animal, in accordance with the theories of Dr. Ivan Pavlov, noted physiologist, by firing the piece and giving the puma a piece of meat after each shot. Soon it overcame its natural dislike for the sound and learned to get its meals by climbing upon a platform and pulling the firing cord.”
Russians were mad genius but weren’t always able to scale. Can you imagine if they had 10,000 cannon leopards when Germany attacked?
