Animal hoarding involves the accumulation of animals beyond the capacity to provide adequate care, creating severe welfare emergencies that intersect with complex human mental health needs.
Animals in hoarding situations experience prolonged suffering from starvation, dehydration, untreated injuries, and infectious disease. Social animals like dogs suffer additionally from inadequate human contact and inappropriate social grouping. Rescue operations are complex because large numbers of severely compromised animals need simultaneous veterinary assessment, housing, and behavioral support. Welfare outcomes for rescued hoarder animals are often poor due to the severity of neglect.
