A Bengal tiger cub that a teenage smuggler tried to sneak into the U.S. is recovering at San Diego Zoo Safari Park after undergoing emergency surgery.

Zoo officials say the tiger cub known as “Moka” is doing well after an operation on March 6 to clear an intestinal blockage that had made him acutely ill. After the surgery, Moka had been under the care of veterinarians and animal keepers and confined for more than three weeks to what’s known as the bedroom area at Tiger Trail in the park until he recovered.
