Sydney: Australia’s Perth zoo has been mourning the death a Sumatran tiger named Setia that had to be killed after a health check revealed a tumour growing in her abdomen.
The decision to put down the animal was made on Tuesday after the lumps were discovered on the 16-year-old Setia during a routine health check, Xinhua news agency reported.
Setia was born at the zoo in 2000 and went on to have four cubs, contributing greatly to the global Sumatran breeding programme.
