The cubs, named Addison and Clark, were born June 26. For the past few months they've been living with their mother, Leafa, behind-the-scenes, officials said.
In addition to the exhibit, visitors can also attend red panda chats every morning at 10 a.m. through Nov. 8 to learn more about the species.
Officials say the cubs have had consistent growth over the past few months; over a month-long period this summer, Clark doubled in weight and Addison tripled in size.
