Franklin Park Zoo Puts Down Christopher the Lion

We are deeply saddened to share that Christopher the lion has died. Over the past two years, the 21-year-old lion was being closely monitored and treated for several irreversible, age-related issues. These included declining kidney function, chronic cystic disease of the liver, and arthritis. Due to his continued declining health in recent weeks, the zoo staff made the decision to humanely euthanize him for quality of life reasons. As he continued to age, his dedicated zookeepers continued to utilize the well-established training programs at the Zoo.
