A hunter killed a mountain lion...and saw a deformity never seen before (photo)

A hunter in Idaho who killed a mountain lion involved in an attack on a dog discovered the lion had a beastly deformity. A set of fangs and whiskers were growing out of its head. A pic released Thursday by Idaho Fish and Game shows the big cat had another set of fully-formed teeth and whiskers growing out of the top of its head.
This type of abnormality, whose Greek name translates to "monster tumor," can grow teeth and hair. In humans, it can grow fingers and toes.
