As Washington, D.C., got its first major snowstorm in two years on January 31, Mei Xiang and Tian Tian -- two giant pandas at the Smithsonian National Zoo -- could be found sliding, tumbling and playing in the snow. The zoo's Giant Panda Cams caught delightful footage of the two grown pandas enjoying the fresh snow. It was also their 5-month-old cub Xiao Qi Ji's first encounter with snow -- but he left the frolicking to his parents.
