In contrast to welfare, animal rights is a non-anthropocentric framework, heavily influenced by the deontological ethics of Immanuel Kant, though extended beyond humans by philosophers like Tom Regan (1983). Regan argues that animals who are "subjects-of-a-life" (possessing beliefs, desires, memory, and a sense of the future) have inherent value independent of their utility to others. Consequently, they possess basic moral rights, most notably the right not to be treated as property. London: FAWC
The concept of legal protection for animals is surprisingly recent.

Animal rights, by contrast, is a more radical philosophical position. It argues that animals have an inherent right to live free from human exploitation and use. Proponents believe that animals are not "property" or "resources," but "persons" in a legal or moral sense.
Critics (including many rights advocates) argue that welfare is a "cage with a bigger window"—it makes people feel better about exploitation without ending it. They point to "humane" labels (e.g., "free-range," "cage-free") as marketing ploys that mask the inherent cruelty of slaughter. As philosopher Gary Francione puts it: "Happy exploitation is still exploitation."
