The Port Defiance Zoo & Aquarium in Tacoma, Wash., has posted a video of zookeepers feeding four clouded leopard quadruplets that were born last week to mother Chai Li and father Nah Fun.
The cubs, which are not on view to the public yet, spend most of their time eating, with two-hour meal times taking place every three hours. The largest weighs about as much as a box of Corn Flakes, the zoo said in a statement.
Native to Southeast Asia, clouded leopards are endangered. They're only bred by about two dozen accredited zoos in North America, so Chai Li giving birth to a litter of four cubs is a rare event, zoo curator Karen Goodrowe Beck said in a statement.
