plantlvr, that is amazing! I'm convinced that lion wanted her for his meal.
I was at the Cincinnati zoo once, where the lion exhibit has the typical large "moat" between the animals and the viewing area. The large male lion was sitting as close to the humans as he could on his ledge and was completely fixated on a little girl about that size. He was doing the deep, repetitive, rhythmic barking thing, never taking his eyes off her. Everyone knew he wanted her for dinner.
The cat in that video had the same expresssion!
