One day in 1969, John Rendall and Anthony Burke saw a real live lion cub in a London department store window.The lion, whom they named Kristyan, is said to have been an affectionate and extremely cooperative cat who even used a giant kitty litter box.Kristyan was brought to Africa where he adapted to life in the wild and eventually became the leader of a group of lions.A year later, Rendall and Burke traveled to Africa to say goodbye.However, when Kristyan saw his old friends, he ran towards them, stood on his back legs, and joyfully gave each of them a long and loving embrace.Kristyan was pampered.
