Research overview: return-to-field and shelter-neuter-return programs

Return-to-field programs sterilize, vaccinate and return healthy unowned cats brought to shelters rather than euthanizing them, and this overview surveys their rationale and evaluation. It examines how these programs aim to reduce shelter euthanasia and intake while managing community cats, the reported effects on shelter statistics and live-release rates, and the overlap with broader trap-neuter-return efforts. The survey discusses the welfare and conservation debates these programs raise, including concerns about returning cats to areas with wildlife or hazards, and the evidence on whether they reduce populations or chiefly shift outcomes. It situates return-to-field within shelter medicine and community cat management, presenting it as an increasingly common practice whose merits and impacts continue to be studied and contested across welfare and conservation perspectives.
