Because of a hobby-like interest in natural science and also because knowledge of anatomy helps him in his work, my husband has a small collection of different animal skulls. It includes the skull of a mountain lion, and the skull of an ordinary housecat. After reading Tribe of Tiger, he got both skulls out and compared them.
Sure enough ... the housecat skull is identical in every way to the mountain lion skull -- except it's a scale miniature.
I love my two housecats and believe they return my affection, but I know that the only reason my remains aren't cat dung buried in dirt somewhere is because I'm about 20 times bigger than they are!
