4 year old cheetah Ophelia was euthanized yesterday.

I met her on my tour last month and she had been doing well.
"It is with a heavy heart that we say goodbye to our beloved cheetah princess, Ophelia. Her care team and Animal Health staff made the very difficult decision to humanely euthanize her on Wednesday.
On June 13, 2019, Ophelia lacerated her Achilles tendon. This sort of injury is very difficult to manage, and even more difficult to resolve. This tendon is vital for extending the ankle, so every time a step is taken, it flexes the joint. An animal like a cheetah that is built to make rapid accelerations puts even more strain on the tendon. Ophelia’s initial injury was repaired in collaboration with a boarded veterinary surgeon at MedVet, and while the repair had been successful for months, it failed on Wednesday, and additional surgical repair was not possible.
Ophelia was born on December 4, 2016 and arrived at the Columbus Zoo and Aquarium on February 3, 2017, along with her sisters, Isabelle and Luciana. Ophelia was very special to her care team, as well as our supportive community. In her sweet and eventful life, Ophelia expressed her royal demeanor by purring loudly, hissing at brooms, grooming her sisters and getting her tail brushed by her keepers. She also loved going on walks and purring at her fans on the Heart of Africa boardwalk. Ophelia’s favorite enrichment was whole eggplants, which she enjoyed carrying around her habitat.
One of the most valuable lessons Ophelia taught her care team was resilience. She loved training and continuously showed how smart she was by quickly learning new behaviors like self-injections, voluntary x-rays and shifting between houses in her behind-the-scenes suites. Her care team says she was always one step ahead of them, and when they caught up, she would be waiting with purrs."
