Two month-old cheetah cubs are the latest addition to the Smithsonian National Zoo. The cubs arrived at the zoo on May 18 after narrowly avoiding death. Their mother, 5-year-old Ally, gave birth to the first cub, but then abandoned him. A team of veterinarians at the Smithsonian Conservation Biology Institute in Front Royal, Va., were forced to perform an emergency cesarean section to rescue the additional three cubs in her litter. After hours of CPR and treatment, one of the three cubs survived. Now, the two surviving cubs must be bottle fed by zoo keepers every few hours, according to the Smithsonian, and will receive care around the clock to nurse them to health. The siblings will make their public debut this summer.
