You've heard of a bear hug, but what about a lion hug?
Check out this video of Sirga the lioness hugging conservationist Valentin Gruener. Gruener and his colleague Mikkel Legarth rescued Sirga when she was just a cub after she'd been exiled from her family. They raised her, and now she resides at the Modisa Wildlife Project in Botswana.
Sirga weighs 110 pounds, and is almost as tall as her rescuer, but you can see he's not particularly afraid of her. They hug, play, and even wrestle together.
