Leo the lion, Shere Khan the tiger and Baloo the bear have been together ever since the animals were rescued from a drug baron's home in Atlanta. Sadly, Leo underwent surgery in mid-August — after several weeks of being severely ill — and veterinarians discovered that more than 80 percent of his liver was full of tumors. Because of the findings, they decided to let the lion go. "Both Baloo and Shere Khan were able say goodbye to their lion brother, and we will monitor them closely for any signs of stress or depression as they are grieving the loss of a family member as well," the sanctuary posted in a statement on Facebook.
