Abstract
Currently an unprecedented number of individuals live in captivity. There has been an increase in attention to the harms of human bondage and confinement, and the harms of captivity for non-human animals is beginning to come into sharper view. Those who do focus on other animals in captivity have tended to focused on pain, suffering, and killing with much less attention to the potentially devastating effects of denying liberty. Incaceration does cause physical and psychological harm, but it also is a violation of autonomy. I argue that other animals have autonomy, they make choices within their species-typical behavioral repertoire and these choices are meaningful to them. Denying them the freedom to exercise their autonomy by keeping them incarcerated, under captive control, is thus ethically problematic.
