Animal Legal Defense Fund http://aldf.org/

"Deprived of legal protection, animals are defenseless against exploitation and abuse by humans. Through the Animal Bill of Rights, the Animal Legal Defense Fund is working to show Congress a groundswell of support for legislation that protects animals and recognizes that, like all sentient beings, animals are entitled to basic legal rights in our society

More than a quarter-million Americans have already signed the Animal Legal Defense Fund’s Animal Bill of Rights. Sign on your support and speak out to your lawmakers today"
