The Sacramento Zoo’s Sumatran tiger will be undergoing chemotherapy after being diagnosed with lymphoma, officials announced Tuesday.

Zoo staff noticed that Castro, who has been at the zoo since 1999, wasn’t eating and had become lethargic. He didn’t respond to his first treatment, Castro was taken in for a more thorough examination. Castro was soon given the diagnosis of lymphoma – a kind of cancer that affects white blood cells.

“While Castro’s prognosis is not good, we feel that this combination of drugs will give the best chance of curing his cancer while making sure that he has a good quality of life,” said Dr. Ray Wack, head of veterinary medicine at the Zoo and a UC Davis School of Veterinary Medicine professor in a statement.

Castro’s chemotherapy drugs will be hidden in his food.

The 15-year-old big cat is one of only about 700 Sumatran tigers left in the world. He lives with a female partner, named Bahagia, and has fathered four cubs.
