Betty White accepts the legend award at the TV Land Awards at the Saban Theatre April 11, 2015, in Beverly Hills, Calif. The late Betty White was a tireless advocate for animals for her entire life, from caring for homeless animals as a child to launching her own weekly TV show “The Pet Set” dedicated to her celebrity friends and their pets. Her biggest contribution, though, may be yet to come, as fans get set to donate to animal welfare charities and local shelters on Jan. 17, 2022, as part of the #BettyWhiteChallenge.
