I argue that animals have rights in the sense of having valid claims, which might turn out to be actual rights as society advances and new scientific-technological developments facilitate finding alternative ways of satisfying our vital interests without using animals. Animals have a right to life, to liberty in the sense of freedom of movement and communication, to subsistence, to relief from suffering, and to security against attacks on their physical existence. Animals’ interest in living, freedom, subsistence, and security are (...) of vital importance to them, and they do not belong to us; they are not the things we have already possessed by virtue of our own nature.
