This article argues that the relations of social and political power that obtain between humans and pets are illegitimate. We begin by showing that pets, a largely neglected population in political philosophy, are subject to socially and politically organised power, which stands in need of justification. We then argue that pets have three moral complaints against the relations of power to which they are subject. First, our power over pets disrespects their moral independence: the fact that they are not simply (...) available to be used to serve the interests or projects of others. Second, our power over pets systematically sets back their interests in exercising control over their own body, actions, and environment. Third, in subjecting pets to asymmetric relations of power in which they are heavily dependent on humans for the satisfaction of their interests, we subject them to objectionable risks of harm. Together, these complaints support our thesis that the power relations central to the institution of pet keeping are illegitimate. The practical upshot is that we have a strong moral reason to abolish this institution. (shrink)
