These photos provided by the Oklahoma City Zoo taken, March 25, 2017, left, and Nov. 23, 2017, right, show Bridget, a lioness that has grown a mane. The Oklahoma City Zoo says the 18-year-old African lioness has died. The zoo says that Bridget was euthanized Wednesday, April 4, 2018, after a veterinary team determined she was likely suffering from heart failure or infection. The zoo says Bridget had been lethargic, not eating and appeared to be in pain. (Amanda Sorenson/Oklahoma City Zoo via AP)
