Lulu was found as a newborn, dehydrated and alone beside a dried-up seasonal river. The keepers at Reteti raised her on specialized formula, and she grew into a gangly, curious calf. But three months ago, Lulu began refusing her bottle. She would stand apart from the other calves, swaying slightly, her trunk limp. The veterinary team ran every test: fecal floats for parasites, blood panels for infections, even a PCR for elephant endotheliotropic herpesvirus (EEHV), the scourge of captive elephant calves. All results came back normal.
