See the moment when the lion recognizes the guys who raised him as a cub:
I quite believe it, but a note from painful personal experience: even a hand-raised lion trying to be friendly can leave scars without meaning to. I don't mean little things, but deep nasty wounds leaving puckered scars and I'm lucky no nerve or tendon damage.
Lions are freaking strong, and have sharp claws.
Even our little Felix Sylvestrus can leave scars. The scale might be smaller but they still have all the attitude of the big cats.
AWW!! Nothing like crying at 8 am :)
