Video of the reunion of with Christian the Lion

Here is a crazy cute video of two roommates who bought a lion cub back in 1969 and their reunion with the then fully grown lion a year later in Africa.

From all my animal behavior courses I should mention that with cats, a it is a pretty big sign of affection when they rub the top of their head on you. When they just rub the side of their head on you it is still friendly but more of a marking their territory.
