This makes me happy. I've watched it about 30 times today. The woman found this lion in a forest as he was dying. She took him home and nursed him back to health. She had him in her home for months. She got him to a zoo and visits him all the time. He greets her the same way every time.
In other lion news, 9 lions attacked a man leaving only his skull and spine. That's way cooler, but there's no video.
