MADISON, Wis - A chimpanzee from the Henry Vilas Zoo in Madison died following a physical examination, according to zoo officials.
Casey was a 31-year-old male chimp who was being examined as part of a preventative medicine program. He died during the anesthetic recovery process, according to zoo officials.
"Casey was a well-loved animal and a favorite of many at our zoo. He will be dearly missed by zoo staff and the community," said Ronda Schwetz, zoo director.
The tests conducted on Casey included blood collection to evaluate liver, kidney, and other organ function, and to test for diabetes and other metabolic diseases.
