SACRAMENTO, Calif. (AP) — A Sumatran tiger is undergoing surgery at the Sacramento Zoo's veterinary hospital to remove stones that have been obstructing the big cat's urinary tract.

Veterinary surgeons from the University of California, Davis School of Veterinary Medicine and the zoo began performing the minimally invasive procedure on Tuesday morning. Doctors planned to implant thin, flexible tubes called ureteral stents that will allow urine to drain normally from the cat's kidneys to its bladder.

The 15-year-old male tiger named Castro is originally from Sumatra, an island in western Indonesia. It has been at the Sacramento Zoo since 1999.

It is one of about 200 Sumatran tigers in zoos around the world. Fewer than 500 are believed to live in the wild.

Earlier this year, Castro was diagnosed with lymphoma, a type of cancer. It is undergoing chemotherapy.
