Experienced animal trainers take a stool with them when they step into a cage with a lion. Why a stool? It tames the lion better than anything – except maybe a tranquilizer gun. When the trainer holds the stool with the legs extended towards the lion’s face, the animal tries to focus on all four legs at once. And that paralyses him. Dived focus always works against you.
