Animal hoarding — keeping large numbers of animals without adequate care — creates severe welfare emergencies involving neglect, malnutrition, and disease that affect hundreds of thousands of animals annually.
Animal hoarding represents one of the most severe forms of companion animal welfare failure because the neglect is systematic, long-term, and often involves large numbers of animals simultaneously. Animals in hoarding situations experience chronic malnutrition, untreated dental and other disease, severe behavioral stress from overcrowding, and the psychosocial disruption of living in disorganized, neglected environments. The welfare harm is compounded by the duration: hoarding situations often persist for years before being discovered, meaning individual animals may have experienced prolonged neglect throughout their lives. Effective intervention requires both welfare rescue of affected animals and mental health support for hoarders to prevent recurrence. The welfare system needs both adequate emergency response capacity for discovered situations and community-level early warning systems that identify developing situations before they become severe.
