Hoover’s son, Allen Henry Hoover, had 2 gators that the president sometimes let run around the White House grounds. John Quincy Adams’ gator was a gift from the Marquis de Lafayette. Adams let it live in the bathroom. Of course, neither of these eccentric presidential pet-owners hold a candle to Calvin Coolidge. In addition to his many dogs, Coolidge had a donkey, a bobcat, lion cubs, a bear, a wallaby, and a pygmy hippo.
