Walter, a 14-month-old warthog that had lived at Utah’s Hogle Zoo since June, has died, the zoo reported Wednesday.
Walter suffered complications from stones in his bladder and urethra, and was euthanized Tuesday.
Zoo officials said in a statement that Walter had not been eating well, and was having difficulty urinating. Veterinarians found Walter had stones in his bladder and his urethra, the tube that carries urine from the bladder out of the body.
Veterinarians operated to remove the bladder stones, but the stone in his urethra could not be removed. They placed a catheter, allowing urine to leave Walter’s distended bladder, and attempted an endoscopy to remove the stone.
