Telluride says goodbye to Ruby the mountain lion. Rescued from a U.S. Department of Agriculture fur farm, Ruby went on to live at the Rocky Mountain Ark Wildlife Rehabilitation Center and lived to be the oldest mountain lion in the world. After suffering from ailments associated with old age, she was put down this spring. In this video, Ramona interviews Melissa Margetts, who used Ruby to teach people about mountain lions and safety around wild animals.
