A singer and actress during the 50s and 60s, Doris Day is now a dedicated animal rights activist. After retiring she became one of the founding members of Actors and Others for Animals, along with other stars who wanted to use their celebrity to raise awareness about the unfair treatment of animals. She also rescued and fostered many animals at her house, which led her to found the non-profit rescue organization the Doris Day Pet Foundation in 1978. To complement the Doris Day Pet Foundation, she formed the Doris Day Animal League in 1987.
In 2007, the Doris Day Animal League merged with the Humane Society of the United States, while the Doris Day Pet Foundation has grown from a grassroots rescue organization into the Doris Day Animal Foundation, a grant-giving non-profit that funds other organizations which share its mission of “helping animals and the people who love them. Day even made a brief return to television in the mid-1980s for a show about animals called Doris Day's Best Friends.
