Sun bears are the smallest bear species and face significant welfare challenges in captivity, particularly when rescued from bile farming or the pet trade, requiring complex enrichment and sensitive social management.
Sun bear welfare in captivity is significantly influenced by the animal's prior history. Bears rescued from bile farming facilities or the pet trade frequently arrive with chronic pain from surgical bile duct catheterisation, severe stereotypic behaviour from prolonged confinement, and profound psychological trauma. Rehabilitation requires patient, trauma-informed management that prioritises safety, agency, and gradual exposure to complex environments. Naturalistic enclosures with forest vegetation, climbing structures, pools, and complex substrates for foraging provide essential environmental complexity. Honey feeding enrichment that requires extraction behaviours uses the bears' extraordinary tongues and occupies significant time productively. Social management requires careful individual assessment — some bears develop meaningful social relationships with conspecifics in rescue settings, while others require individual management. The welfare goal for rescued bears is not restoration to full wildness but provision of the best possible quality of life given their history and capacity — an honest assessment that accepts some individuals will always carry the scars of their early experience.
