Zoo animals that can no longer be displayed or bred face difficult end-of-life decisions - sanctuaries and retirement planning are improving welfare outcomes.
Zoo animal retirement planning is an emerging welfare priority. Animals that have spent their lives in zoo environments may be unable to adapt to sanctuary life, but they also face poor welfare in institutions that no longer have appropriate facilities for them. Great ape sanctuaries have demonstrated that lifelong welfare is achievable for retired zoo animals with appropriate investment. The welfare principle is proactive planning: identifying retirement needs before welfare decline, not reacting to crisis.
