He's back! National Zoo officials have found Rusty, the missing red panda who was on the lam this morning. The zoo thanked everyone who helped looked for the furry fella in a tweet. Rusty went missing on Sunday night around 6 p.m., and the zoo said it would be “unusual for Rusty to wander far from his home range, in this case, his exhibit.” “Animal care staff have been combing the trees around the Zoo since 8 a.m. He could be sick and hiding, or someone could have taken him,” zoo officials also said.
