Bears in captivity have complex needs that are challenging to meet. Understanding what distinguishes poor welfare zoo enclosures from well-designed sanctuary environments matters for bear protection.
Bears are among the most cognitively complex and wide-ranging mammals, making them particularly unsuited to small enclosures. Polar bears in small traditional exhibits pace incessantly — a stereotypy indicating profound psychological distress. Brown and black bear exhibits that allow foraging, climbing, and swimming substantially improve welfare, but even the best zoo environments represent a fraction of natural home ranges. Bile bear farming represents one of the most severe systematic welfare failures in existence: bears kept for years in crush cages barely large enough to contain them, with metal catheters or implanted devices penetrating their gallbladders. Sanctuaries that rescue bile bears demonstrate that recovery is possible with patience and appropriate care.
