We are heartbroken to share the loss of California sea lion Kenney (4), who passed away on May 15, 2026.
On May 10, Kenney’s care team noticed he was suddenly lethargic, had lost his appetite, and was experiencing GI issues. Within a few days, his condition became severe very quickly, and we placed him under advanced veterinary care.
Committed to improving Kenney’s condition and ensuring his continued comfort, our expert care team consulted specialists, collected diagnostic samples, and performed blood work and imaging to learn more about the cause of his acute illness and guide his treatment plan. Despite quick and rigorous medical intervention over multiple days, Kenney developed acute liver failure and passed away a few days later.
Hogle Zoo conducted a full-body CT scan and necropsy to understand more and continue to work closely with health partners to advance pinniped diagnostic knowledge. At this time, the other Rocky Shores residents Maverick, Banana, Mira, and Nika are not experiencing similar symptoms but are still being monitored.
Earlier this spring, Kenney joined Hogle Zoo from Shedd Aquarium on a recommendation from the Association of Zoos and Aquariums (AZA) Species Survival Plan (SSP). Loved for his curious and playful personality, Kenney enjoyed interacting and playing with enrichment.
Kenney’s passing is deeply felt by the Hogle Zoo and Shedd Aquarium teams, and we understand it’s difficult news for our community to process alongside us.
Thank you for your support and understanding as we mourn.
