Every time I walk past the National Zoo, I worry that a large cat of some sort has escaped & is lurking in the shrubbery waiting to tear me to shreds. And you probably gave me a little mental chuckle as you read that, but I want you to know: This is a serious fear. And, I think, a somewhat rational one.
Death by surprise cheetah (or leopard or tiger or lion or panther) attack is NOT the way I want to go. Be careful walking home, kids.
