BOSTON (AP) - Ernest Hemingway shows a tender side in previously unpublished letters being made public by the Kennedy presidential library in Boston.
    
In a letter to his friend Gianfranco Ivancich written in Cuba and dated February 1953, Hemingway writes of euthanizing his cat "Uncle Willie" after it was hit by a car.
    
The author writes: "Have had to shoot people but never anyone I knew and loved for eleven years. Nor anyone that purred with two broken legs."
    
The letters span from 1953 to 1960, a year before the prize-winning writer's suicide.
