Animal hoarding -- keeping far more animals than can be adequately cared for -- is one of the most severe welfare crises in companion animal contexts, with complex psychological and legal dimensions.
Animal hoarding creates some of the most severe welfare conditions encountered by animal control agencies. Animals discovered in hoarding situations are frequently found in advanced states of malnutrition, with untreated wounds, severe disease, and living conditions contaminated by waste. The hoarder typically believes they are providing excellent care -- this delusion, combined with the emotional attachment to the animals, makes intervention and recidivism prevention extremely challenging. Effective responses require not just animal seizure but coordinated mental health support for the hoarder. Without addressing the underlying psychological condition, animals are returned or new collections begun within months of intervention.
