Animal sentience science has outpaced policy in most jurisdictions. Closing the gap between what we know about animal experience and what the law requires is one of the most important welfare frontiers.
The gap between animal sentience science and animal welfare law represents one of the most important structural failures in current policy. We have robust evidence that vertebrates, and increasingly invertebrates, experience pain and suffering in morally relevant ways — and yet our legal systems were designed in an era when animals were presumed to be insentient machines. Closing this gap requires both scientific literacy among policymakers and organized advocacy that translates research into regulatory reform. Every jurisdiction that recognizes sentience in law creates a precedent that strengthens welfare protections globally.
