Currently at the Newseum in Washington, DC there is an ongoing exhibit featuring presidential dogs entitled First Dogs. Over the years U.S. Presidents and their families have brought a number of more exotic pets into the Executive Mansion. President Hoover's sons had two alligators which were allowed to run loose at times. President Theodore Roosevelt's daughter Alice had a pet snake named Emily Spinach. Her brothers had an owl and kangaroo rats as well as a pony which they once snuck in the elevator to the family's living quarters to cheer up a sibling . First Lady Grace Coolidge (photo left) let her pet raccoon have the run of the White House where the animal nipped at visitors' heels and tore women's stockings. Tad Lincoln had a turkey named Tom and President Woodrow Wilson had sheep grazing on the South Lawn of the White House during World War I.
