Animal welfare laws vary enormously between countries, with ongoing progress in extending protections to more species and practices globally, though significant gaps remain.
Legal frameworks for animal welfare have expanded significantly in recent decades but remain inconsistent across species and jurisdictions. Farm animals receive far weaker protections than companion animals in most countries despite similar capacity for suffering. Invertebrates are excluded from most welfare legislation globally despite growing evidence of sentience in crustaceans and cephalopods. Enforcement of existing laws is often inadequate due to resource constraints and cultural norms. The direction of legal change is generally positive — more species, more practices, and more meaningful protections — but the pace is slower than the welfare science would justify.
