This endangered Sumatran Tiger named Castro Jr., or C.J. as he is commonly known, was born on March 3, 2013 at the Sacramento Zoo where he was a favorite among guests. C.J was moved to the LA Zoo  and made his public debut on February 6, 2015.<br />

C.J. is a potential breeding partner for the Zoo's female Sumatran Tiger, Indah, because the Sumatran tiger is one of the most endangered subspecies of tiger in the world. There are less than 400 left in the wild.
