Photo of the day: Olympic zoo babies
A pair of 3-month-old cheetah cubs investigate their new enclosure on July 24 while making their official public debut at the Smithsonian National Zoo in Washington, D.C. The debut comes just days before the opening of the Olympic Games in London. In honor of the world event, the cubs — a male and a female — will be named after the fastest American male and female runners in the 100-meter dash.
