Animal welfare science is evolving beyond preventing suffering toward actively promoting positive states and flourishing in animals under human care.
The shift from welfare-as-harm-prevention to welfare-as-flourishing represents a profound ethical evolution. If we accept that animals can experience positive states like joy, play, curiosity, and contentment, then the goal of animal welfare is not merely to ensure animals do not suffer but to ensure they have opportunities to thrive. This reframing has practical implications: it suggests that even pain-free animals in barren environments are experiencing welfare deficits, and that enrichment, positive training, and opportunities for natural behavior expression are welfare requirements, not luxuries.
