You learn something new every day : when Momma curls back her lip after licking the cubs, it's called the Flehmen response. Lions have a vomeronasal organ located on the roof of the mouth, and curling back her lip so helps expose the vomeronasal organ and draws scent molecules back toward it.

So even though she looks like she's going "Ew yuck ptoo-i", she's really smelling!
