We all know that Lions, Tigers, Leopards, Cheetahs and so on are referred to as "Big Cats". A Florida based organisation called "Big Cat Rescue" manages an educational, non-breeding sanctuary for big cats in Tampa. They conducted an experiment by fitting a rear-facing camera to a worker's head to capture what the cats did (or were intent on doing) behind his back... literally!
What you will find in this short, under 2 minutes long video clip is that all the rearing and training cannot rid these magnificent creatures of their instinct. A must watch!
