DENVER — The Denver Zoo has two new red pandas. The female cubs were born June 6.

Lali and Masu are currently in a nesting box being cared for by their mother, Faith, and spend most of their time sleeping.

While in the nesting box, zoo visitors won’t get many chances to see the cubs. That will change in September when they’ll be ready to join their father, Hamlet, in the red panda exhibit.

After being born, the cubs were not gaining weight or regulating their body temperatures, the zoo said. Both were diagnosed with pneumonia and started on daily tube feedings, antibiotics and fluids.

They’re doing better now and have begun opening their eyes.

Red pandas are native to Asia and are classified as an endangered species. Like giant pandas, they eat lots of bamboo.
