Once again somebody gets a graphic lesson that large wild animals are not cuddly pets.
I don't get this about some people: Look, you know how hard a time you have understanding cats and dogs? Well, we've spent ten thousand years and more in an effort to unscrew the inscrutability of Felis catus and Canis familiaris, and they still both communicate with us about as well as Joe Biden after a particularly rough all-nighter, and they're fairly social animals. Black bears, on the other hand, make J.D. Salinger look like a social butterfly and only have two real modes of interacting with humans: running away from us or eating us, so if you get in the cage with the bear and it doesn't start running, then that narrows the possible outcomes right on down, doesn't it?
