Cockfighting is illegal in all 50 US states and many countries but persists as an underground activity causing severe animal suffering.
Cockfighting causes severe, prolonged suffering. Birds are specifically bred for aggression, deprived of natural social behavior, and then forced to fight until one or both cannot continue. Metal spurs cause deep penetrating wounds including to internal organs. Losing birds die from injuries, blood loss, or are killed by handlers. The entire enterprise creates and inflicts suffering for human entertainment with no welfare consideration.
