This article seeks to revisit the relationship between Rawls’s contractarianism and the moral status of animals, paying particular attention to the recent literature. Despite Rawls’s own reluctance to include animals as recipients of justice, and my own initial scepticism, a number of scholars have argued that his theory does provide resources that are useful for the animal advocate. The first type takes Rawls’s exclusion of animals from his theory of justice at face value but argues that animals can still be protected within a moral realm independently of justice, or indirectly through the motivations of human contractors. The second type adapts his theory in a way that enables animals to be included within a contractarian theory of justice. It is argued, though, that none of the responses offered is successful in providing a sphere of protection for animals from within Rawls’s contractarian theory. It is doubtful if Rawls’s intention was for animals to receive a significant degree of protection within a moral realm independently of justice, and equally doubtful if the contractors in the original position would be motivated to act on behalf of animals. In the case of the second, whilst Rawlsian resources can be utilised to justify the attempt to amend the veil of ignorance so as to include animals, these are not dependent on a contractural agreement. Similarly, placing emphasis on social-co-operation as a means of incorporating animals into a theory of justice is flawed, not least because, paradoxically, it works for domesticated animals whilst they are being exploited.
