Hoshi, the Indochinese tiger who joined the Charles Paddock Zoo in fall 2000, was found dead in his den Sunday.
Zoo Director Alan Baker said Hoshi died from asphyxiation caused by Sala, his long-time exhibit mate. Laboratory results are pending, according to statement from the zoo.
Hoshi was born in February 2000 at the Cincinnati Zoo and joined the Atascadero zoo later that year, Baker said.
Sala will stay on display during regular visiting hours.
