Last Chance for Animals (LCA) recognizes that animals have the ability to experience pain, and as such they deserve certain basic rights protecting them from pain caused by humans. LCA believes that non-human animals should not be subjected to suffering and exploitation by humans because alternatives exist for nearly every traditional "usage" of animals. LCA opposes the use of animals for scientific curiosity, entertainment, clothing, and food. LCA recognizes the use of non-human animals in medical experimentation as both immoral and of questionable scientific validity due to the tremendous biological difference between species. LCA's work advocates conscious and informed lifestyle decisions, and the organization is committed to disseminating truthful information about societal animal abuse to improve the treatment of animals.
