An Illinois zoo is grieving after two of its lions died less than two weeks apart.
"Despite the immediate and intensive treatment provided by the veterinary staff, Isis sustained significant injuries and the difficult decision was made to humanely euthanize her today," the non-profit said.
The death comes less than two weeks after a 13-year-old male African lion, Zenda, was euthanized "due to age-related issues that impacted his quality of life." Zenda and Isis were mates, the zoological society said.
Zenda and Isis arrived at Brookfield Zoo in 2008 and shared a strong emotional bond. They were often seen grooming each other or sleeping together.
“Isis and her mate were majestic animals who had a strong bond. The staff, who dedicated their lives to care for these charismatic lions, are heartbroken by their loss,” added Zeigler.
Zoo staff checked on Isis around 9:00 am on Monday and she was fine. But about 30 minutes later, they found her at the bottom of the mote in her enclosure, where they believe she fell some 15 feet and sustained injuries. Isis was euthanized on Tuesday.
“This habitat has held large cats since 1934, and this is the first time we’ve experienced a traumatic injury like this from an animal going into the moat," Zeigler told the newspaper. “We are looking at the habitat, and whether there will be modifications made will be determined.”
“The safety and well-being of the animals in our care is our utmost priority,” Bill Zeigler said. “Although it is unclear what caused her fall, we are reviewing all aspects of this tragic occurrence.”
