Animal hoarding is a complex, often underrecognized public health problem affecting the health and welfare of humans and animals. Limited peer review literature exists on the conditions, outcomes, and resources needed to care for cats from hoarding environments in shelter settings. This study investigated intake medical conditions and outcomes of cats surrendered from hoarding environments to the New York City sheltering programs of the American Society for the Prevention of Cruelty to Animals (ASPCA). The objectives of this study were to (1) describe the prevalence of medical conditions at intake; (2) identify associations between medical conditions and outcomes; (3) summarize key interventions provided prior to outcome and (4) compare outcomes of cats surrendered from hoarding environments to other owner-surrendered cats.
