       When Joe Biden became the 46th US president in 2021, two dogs followed him and his family into the White House---and were kicked out shortly after they moved in. The German shepherds Champ and Major were sent away for training after Major bit one of the president’s security guards. But this wasn’t the first time a president’s pets had made the news.

       President Bill Clinton had a charming cat named Socks. The cat was often featured in magazine and newspaper photos, and even received fan mail. A White House staff member answered the letters.

The two fought constantly.

       The family of President John F. Kennedy lived up to their celebrity reputations by taking in glamorous pets--- horses. They had four of them during Kennedy’s short presidency between 1961 and 1963. Two horses, Macaroni and Tex, belonged to his young daughter Caroline. After she and Macaroni appeared on the cover of Life magazine, the popular singer Neil Diamond was inspired to write the hit song “Sweet Caroline.”

       Pets are known to benefit mental health, as they help people stay calm and feel loved. Perhaps that fact explains why the only three presidents not to have pets---Andrew Johnson, James Polk, and Donald Trump---might be ranked among the worst US presidents in history.
