KC the bobcat unexpectedly died at the Abilene Zoo.
The zoo's veterinarian says the bobcat most likely died from a bladder rupture that was caused by a urinary tract obstruction. The doctor says this is a common emergency occurrence in cats.
KC lived at the zoo since August 2010. He was originally found as a kitten with a viral infection. He was treated at a wildlife rehabilitation center in Oklahoma, but was the only bobcat to survive from his litter.
Because he was raised by humans, he was unable to return to the wild.
Abilene Zoo officials are not sure if and when they will find a replacement for KC's exhibit.
