Animal Property Rights: A Theory of Habitat Rights for Wild Animals represents the first attempt to extend liberal property rights theory across the species barrier to animals. In addition to a theory of animal property rights, Animal Property Rights affords a critique of Donaldson and Kymlicka's wild animal sovereignty theory, a defence of indirect approaches to animal rights, an extensive discussion of euthanasia as a 'therapeutic hunting' tool, and the first discussion of Locke's theory of original acquisition in animal rights literature.
