Look at the attached picture first and then watch the video. These 2 guys reared this lion from a baby in England but the authorities would not allow them to keep her once she reached maturity (which, I don't entirely disagree with -- I mean a London flat is not the right place for a cat of that magnitude to be happy and healthy). So decided to take her back to Africa and placed it in a wildlife sanctuary. A year later they went to see her and were told she would not likely remember them.

(I have to note that I particualrly love how the first thing she does is to recreate a "family scent" -- the mixed scent created from rubbing cheeks together. My cats do that do me everytime I come home. It's funny no matter how big or small, certain behavioral aspects remain the same.)
