LOUISVILLE, Ky. (WDRB) — The Louisville Zoo announced that its remaining maned wolf has died.

Sadie, 12, was humanely euthanized after a decline in health related to both her age and a long-standing chronic gastrointestinal disease, a common illness for the species.

Back in 2016, her zookeepers partnered with experts to create “Sadie’s Stew," a specialized diet tailored to her needs.

The groundbreaking formula not only improved Sadie’s health, but also became a model for maned wolf care in several zoos across North America.

Sadie came to the Louisville Zoo in 2014 from Sunset Zoo in Kansas. She welcomed two pups, Cora and Catina, on Valentine’s Day 2017.

Her pups will carry forward her legacy of care and conservation.
