WTF do they expect???

These are Wild Animals, not cute furry pets. The fact that they are caged in a zoo does not change their nature.

They need to eat, and, if not fed, will hunt for their food.
They hunt, and kill, other animals.
They are predators, doing what predators do.

NEW ORLEANS -- Eight animals have now died after a jaguar escaped from its habitat at the Audubon Zoo in New Orleans. CBS affiliate WWL-TV reports an alpaca and fox died Sunday, the day after the male jaguar killed four alpacas, one emu and one fox Saturday morning.

To expect any other behavior is to show your ignorance.
