#LomelokWatch: A Lion Cub Timeline

March 7, 2024

Lomelok the African lion cub has captured hearts as part of the lion pride here at Lincoln Park Zoo. He is getting support from around the world, from those who visit him in Chicago to those who watch the pride daily on zoolife.

A unique lion cub, Lomelok has had mobility issues since he could walk and has recently undergone a surgery to address a herniated disc. Below is a timeline of his and his littermates’ lives to this point. Please check back for updates as Lomelok continues on his long road to recovery.

October 14, 2021 – The new Pepper Family Wildlife Center opens with male Jabari and females Zari, Hasira, and Cleo. Built using data gathered through ZooMonitor, Lincoln Park Zoo’s behavior tracking software, it’s designed with the lions’ preferences in mind.

March 15, 2022 – Proving that the new habitat is successfully meeting the animals’ needs, Zari gives birth to her first lion cub, Pilipili. The birth is part of the African Lion Species Survival Plan®.

December 9, 2022 – Lincoln Park Zoo announces that lioness Zari is pregnant! Zoo staff observed breeding behavior and recorded it through the Lincoln Park Zoo-created app, ZooMonitor. Then, the pregnancy was confirmed via hormone analysis. During a positive-reinforcement training session, Zari voluntarily participated in ultrasound sessions. The zoo institutes #LionWatch so the public can follow all the news.

January 9, 2023Three lion cubs are born to Zari. They meet their first milestones, including nursing within the first few hours of birth.

February 23, 2023 – The zoo announces that the lion cubs have had their first veterinary appointments at the age of six weeks. During an exam that was carefully choreographed to allow 18 keepers, veterinarians, and veterinary techs to give the cubs all the care they required in under eight minutes, the cubs were found to be all males. The three young lions also received vaccinations and had small portions of their fur shaved so they were easily identifiable. Lomelok undergoes radiographs to assess concerns with his mobility and no bone issues are detected.

March 16, 2023 – The lion cubs are named! In partnership with several Ilchokuti, or “lion guardians,” who work with KopeLion in Tanzania, the three youngsters are given names in the Maasai language. They will be called Pesho, or “unexpected gift”; Sidai, which means “good”; and Lomelok, which means “sweet.”

April 14, 2023 – After months of bonding with other pride members behind the scenes, Pesho, Lomelok, and Sidai make their debut in the outdoor habitat at Pepper Family Wildlife Center.

May 31, 2023 – Following observations of Lomelok since birth that indicate he is having rear limb mobility issues and low activity levels, the young lion undergoes more testing. He volunteers for a hand injection from his care team and is sedated. He receives a full examination from zoo vets that includes radiographs and bloodwork. No answers are provided immediately, but Animal Care staff and others keep a close eye on him.

June 3, 2023 ­­– With initial examinations inconclusive, the zoo turns expands testing and consults with MedVet Chicago. Lomelok receives a series of advanced diagnostic tests, including more radiographs, a CT scan, an MRI, and an epidural for anti-inflammatory and analgesia. Lomelok is diagnosed with a conformational narrowing (stenosis) of the channels that carry nerves from the spinal cord to the legs. This compresses the nerves. Some days, he appears stiffer than others.

August 10, 2023 ­­– The zoo provides an update, noting that Lomelok remains with his family and continues to learn about life as a lion. Zoo veterinarians continue to augment his treatment to help ease any discomfort and adjust to a quickly growing lion cub.

March 1, 2024 – Following a checkup with the zoo’s partners at MedVet Chicago, Lomelok is diagnosed with a herniated, or slipped disc, near the location of the issue he has experienced since birth and surgery is recommended. The zoo shares a video from zoo veterinarians Dr. Kathryn Gamble and Dr. Kate Gustavsen, which explains the diagnosis, the surgery, and the risks. While this is a common surgery in humans and pets, there doesn’t appear to be any written precedent for a surgery of this kind in a growing lion cub.

March 5, 2024 – Lomelok undergoes an hours-long surgery at MedVet Chicago to address his disc. It’s a full day that includes anesthesia, transport, diagnostics, preparation, and the operation itself. Following the surgery, he returns to the zoo and starts his road to recovery. He’ll be under observation 24 hours a day, seven days a week, as the first hours and steps are critical to his health going forward.
