SOUTH BEND, Ind. (AP) — Ailing animals at a northern Indiana zoo are getting high-tech help from Goshen Hospital.

The Potawatomi Zoo in South Bend has a long history of using ultrasound to detect health problems in animals. But Dr. Ronan Eustace, the zoo’s veterinarian, says a newer model donated by the hospital is “vastly superior.”

Eustace tells The Elkhart Truth that zoo staff use ultrasound to peer inside animals, ranging from frogs to big cats. He says ultrasound revealed that a lion was suffering from kidney cancer.

Eustace says an early diagnosis greatly extended the lion’s life because cancer was removed from the kidney before the lion became ill.
