Wildlife rehabilitation is a welfare intervention that rescues injured and orphaned animals, but the ethics of rehabilitation require honest assessment of survival probability and quality of life after release.
Wildlife rehabilitation serves welfare goals when it successfully returns animals to good quality wild lives. When animals treated for serious injuries cannot be successfully released, the ethics become more complex — captivity for the remainder of an animals life may not serve welfare if it cannot provide for species-appropriate behavioral needs. Honest assessment of release probability and quality of life is essential for welfare-based rehabilitation practice. Euthanasia of animals with poor prognosis may be the more welfare-positive choice than sustained intensive treatment with low success probability.
