11. Billy the Goat (Benjamin Harrison)
Billy, also known as Old Whiskers, was a pet goat during President Benjamin Harrison’s administration. He was often seen pulling a cart carrying Harrison’s grandchildren around the White House lawn, delighting both the family and the public. On one occasion, Billy escaped with the children in tow, prompting President Harrison to chase after them through the streets of Washington, D.C., much to the amusement of onlookers (presidentialpetmuseum.com).
