In the end, Hannibal did not administer the fatal bite to his mate's neck. And Jao Chu did not immediately kill their offspring, as is often the case. And so, early yesterday, despite murderous tendencies in the captive species, two newborn clouded leopard cubs were found alive, well and squealing at the National Zoo's Conservation and Research Center in Front Royal, Va.

...do the snow leopards object to being in captivity so much that they like to kill their mate (as is the case for the male to do) or kill their cubs (as is the case for the mother to do)?
