Wellington Zoo's team is mourning the loss of their oldest cheetah, Charlie, who died on Friday aged 13.
Charlie was euthanised following a deterioration in his health which could no longer be managed, said senior vet Baukje Lenting.
"We have been monitoring Charlie's health closely over the last few weeks, as he was going off his food periodically and showing signs of abdominal discomfort.
"Charlie had regular medical examinations as he was affected by chronic pancreatitis."
On Friday, the animal care and veterinary teams carried out an endoscopy and ultrasound to look at his digestive system and take samples of his pancreas.
