Elderly lion Zuri has been euthanased after it became evident that his neurological condition had progressed rapidly over the past week, affecting his ability to move.
Zoo Veterinarian Dr. Sarah Frith says that Zuri was diagnosed with age-related neurological problems several months ago, and that Keepers and Veterinarians have been monitoring his condition closely.
She says that ‘We are expecting the cause to be a degenerative disease of the nerves relating to Zuri’s advanced age.’
Dr. Frith explains that although the necropsy has been carried out at the University of Melbourne’s Veterinary Clinic at Werribee today, the diagnosis will only be confirmed after laboratory testing of the neurological tissues, which may take a few weeks.
Zuri and his two surviving brothers Chaka and Harare were born on New Year’s Day, 2001, so at almost 16 they have lived longer than lions in the wild and even the average Zoo life expectancy for their species.
Carnivores Department Manager Adrian Howard says that ‘I was there the day he was born, and I’ve cared for him for his entire life. There are other Keepers and Veterinarians that have also shared his whole lifetime, and we are all going to feel the loss.
‘Zuri was a majestic and impressive male, but even though he was the biggest of the brothers he was somewhat subordinate to them – he would stand back and allow them to be more dominant.
‘Although Zuri will be deeply missed by the team, when he lost his appetite and found it more difficult to move, we knew this was the right time to say goodbye.
‘Millions of visitors have seen him growing up with his brothers, and for all those years Zuri has done an amazing job as an Ambassador for his species, which is under increasingly serious threat in the wild.’
Melbourne Zoo Director Kevin Tanner says that Zuri will be missed not only by all the Zoo staff but also the Members and other visitors.
‘Our lions have always been a popular display, especially with the three majestic brothers, and even visitors who may not have been to the zoo for a while will all have fond memories of these spectacular animals over the last 16 years.
‘The new Lion Gorge was built on the spot where the three brothers were born, and although we are very sad to lose Zuri his condition had reached the point where our decision was the right one for him.
‘I would like to acknowledge the compassion and professionalism of the team who have provided such excellent care for Zuri during his final illness.’
