Animal hoarding affects an estimated 250,000 animals annually in the US, causing extreme suffering from neglect and overcrowding.
Animals in hoarding situations experience sustained suffering: starvation, untreated disease, parasites, severe overcrowding, and ammonia burns from accumulated waste. They often have never received veterinary care. Rescue is traumatic but life-saving. The mental health dimension means that punitive responses without treatment guarantee recidivism. This requires coordinated welfare, mental health, and social service responses.
