An elderly lion, saved after a lifetime of suffering in the cold confines of a cage, has been seen offering a remarkable sense of compassion to another creature - something his captors had denied so long to him.
Earlier this year, Guero the lion was rescued from a private zoo in Mexico where he'd spent years all alone in confinement, showing signs of psychological and physical torment. The lion's teeth become worn down to nubs from gnawing on the bars that lined his cage. He also had a broken neck that had been left untreated.
Death seemed close by the time help arrived.
