Four cheetah cubs nestle with their mom Tumai at the National Zoo in Washington on February 4, 2005. This is the first litter of cheetah cubs born at the National Zoo during its 115-year history. They were born 10 weeks ago. Cheetahs are the fastest land animals, reaching speeds upwards of 60 miles per hour. (UPI Photo/Pat Benic)
