A Sumatran tiger died Sunday at Point Defiance Zoo & Aquarium in Tacoma.
Bima, 5, had been battling a brief illness, zoo officials said Monday. The cause of his death hasn’t yet been determined.
“He had markedly elevated liver enzymes consistent with hepatitis,” head veterinarian Karen Wolf said in a statement. “We are doing everything possible to identify the cause of his illness as it was sudden and unexpected.”
The tiger had intensive care and treatment for several days before his death, the zoo said.
Never miss a local story.
Bima was born at Point Defiance. Seven other tigers, none who shows signs of being sick, live at the zoo. One is Bima’s mother, Jaya.
Sumatran tigers, an endangered species, are native to the island of Sumatra. About 300 are left in the wild there.
They live about 12 years in the wild, and up to 20 years in zoos, according to the Zoo Atlanta website.
