Zoo officials concerned about tiger cub

A tiger cub born on Mother's Day at the Pittsburgh Zoo and PPG Aquarium is not getting much TLC from its mother. Tiger-keepers are working around the clock to find out why the cub's mother, Toma, isn't being receptive to her newborn. Zoo officials think Toma might be sick or possibly carrying another cub. The two-pound cub is being kept at an animal hospital. If the cub does not receive attention from its mother, it can be raised successfully by tiger-keepers at the zoo. Source: KDKA
