Off-screen, White tirelessly raised money for animal causes such as the Morris Animal Foundation and the Los Angeles Zoo. In 1970-1971, she wrote, produced and hosted a syndicated TV show, “The Pet Set,” to which celebrities brought their dogs and cats. She wrote a 1983 book titled “Betty White’s Pet Love: How Pets Take Care of Us,” and, in 2011, published “Betty & Friends: My Life at the Zoo.”
