Japanese macaques (snow monkeys) are cold-adapted primates kept in zoos globally - their welfare requires outdoor access, appropriate social groups and environmental features matching their unique thermal preferences.
Snow monkey zoo welfare requires recognising their paradoxical thermal biology - cold-adapted but attracted to warmth when available, as demonstrated by hot spring bathing. Facilities must balance outdoor cold access that allows natural thermoregulation with warm retreats. Social management is the primary welfare challenge - natural group sizes of 20-100 individuals cannot be replicated in most zoo settings, requiring careful management of smaller groups to minimise social stress. Cognitive enrichment is essential for highly intelligent primates. Outdoor access year-round, including in winter conditions, is important for their natural thermoregulatory behaviour.
