Tiger cub at L.A. Zoo dies after suffering head trauma

The Los Angeles Zoo today announced that one of three male Sumatran tiger cubs born on Aug. 6 has died.

Zoo officials said a necropsy performed on the cub after it was found dead on Monday indicated it sustained head trauma, but it was not immediately clear how it occurred.

The cub’s mother, Lulu, will continue to raise the two other cubs, according to the zoo. The tiger has successfully raised litters in 2005 and 2007.

Because tiger cubs depend on their mothers for the first year, the zoo said each birth in captivity “is significant and not without risk.”
