Wild pigs (feral hogs) are an invasive species in the US causing agricultural damage, but management methods raise significant welfare concerns.
Warfarin poisoning causes internal hemorrhaging over 5-7 days, one of the most prolonged and painful death methods in use. Aerial gunning wounds animals that escape to die slowly. Leg-hold traps cause prolonged suffering. The intelligence and social complexity of wild pigs means they likely experience significant suffering from these methods. Sounder disruption causes psychological distress to surviving family members.
