TULSA, Oklahoma - Tulsa Zoo lion Kofi passed away over the weekend, News On 6 has learned. The almost 19-year-old lion was placed on hospice care for end stage kidney failure earlier this month.

He was diagnosed with the disease in 2015. Zoo Director of Animal Health Dr. Kay Backues said earlier this month that the decision to humanely euthanize him would be made when his quality of life diminished.

In a news release, the Zoo said he was surrounded by his caregivers in his exhibit holding area when he passed away. 

"Kofi was very interactive with his zookeepers," the release states. "The animal care staff would reserve time to sit with him for the enjoyment his company. Kofi would often sit near the fence, cross his front paws, and hang out for awhile."
