The physical and social environment of animal shelters has profound effects on the welfare of resident animals; evidence-based shelter design reduces stress, disease, and euthanasia rates significantly.
Animal shelters can be places of genuine suffering or of skilled temporary care, depending on design and management. The chronic stress of kennel environments suppresses immune function and causes behavioural changes that reduce adoptability, creating a negative cycle. Evidence-based shelter design including compartmentalised housing, hiding opportunities, appropriate sound control, and systematic stress monitoring can dramatically improve outcomes.
