A young character adopts an abandoned or orphaned baby wild animal and cares for it as a beloved pet. However, when the animal reaches maturity, the character is advised and/or pressured by the adult characters to drive it away so it can live in the wild on its own. With heartbroken reluctance, the young one complies and is profoundly upset as the animal leaves. If it happens early enough in an episode or arc, this may later result in an Androcles' Lion. The fact that a creature raised in captivity will lack the necessary skills to survive in the wild will very rarely be addressed. Nature is loving and nourishing, right?
