United Animal Nations, a 501(c)3 non-profit, was founded by Belton P. Mouras. Based in Sacramento, California, Mr. Mouras led a small group of humane movement workers on a mission to protect animals globally and unify people for the wellbeing of animals. UAN responded to a wide range of animal issues, including: elephant poaching in Africa, pet overpopulation, horse slaughter, whaling, inhumane treatment of primates in research, animals left behind during national disasters, and a variety of other animal cruelty and abuse situations.
