Born almost two weeks ago and weighing between 2 to 3 pounds at the time, the male cubs have been placed in intensive care at the zoo's Animal Health Center after struggling with feeding, according to the Columbus Dispatch.

Fortunately, zoo officials have said the pair's condition is improving.
"The tiger cubs are doing great, they are taking their bottles with vigor and gaining weight every day. Their eyes are just starting to open," Dusty Lombardi, the zoo's vice president of animal care and conservation told The Huffington Post Wednesday. "They have very different personalities: Cub number one is very timid and shy and sweet; cub number two knows what he wants and goes for it."
The first offspring for five-year-old female, Mara, and nine-year-old male, Foli, the cubs are the first amur tigers ever born at the Columbus Zoo. The last birth of any tiger subspecies at the Columbus Zoo occurred in 1990.
