Legal recognition of farm animal sentience — the capacity to feel — is fundamental to meaningful welfare protection and has been enacted in several major jurisdictions.
Legal recognition of sentience matters because it shifts the basis of welfare protection from property law to a recognition that animals have inherent interests in avoiding pain. Without sentience recognition, animal welfare is framed as property damage — harming what belongs to the owner — rather than harm to a being with its own interests. Sentience recognition changes the moral and legal architecture of welfare protection.
