Farm Sanctuary has successfully banned various confinement systems of farm animals by supporting voter referendums. In 2002, Farm Sanctuary was part of a coalition of groups that comprised Floridians for Humane Farms, which sponsored the initiative that amended the Florida Constitution to limit the "cruel and inhumane confinement of pigs during pregnancy." The measure, which passed with 55 percent approval, outlaws caging pigs in gestation stalls, which are metal enclosures that measure two feet across and prevent sows from turning around freely.
