Zoo Knoxville says the 4-week-old African lion cub died of a fatal injury inflicted on her by her mother, who was recovering from anesthesia after surgery.
The big cat and the hyena fought in a battle of wills in South Africa.
A swarm of hyenas and vultures discovered why it's best not to mess with the king's meal in South Africa.
The calf appeared to be left for dead in Kenya's Masai Mara.
She disappeared by the time security got to the scene, and was apparently unharmed.
The predator seized the opportunity as the mother lioness went hunting in Tanzania.
Lions and tigers at the National Zoo in Washington, D.C., tested positive for the coronavirus last week.
The big cats are also showing symptoms such as coughing and lack of appetite.
"This little fella was up for it," one of the videographers said.
The animals were mostly likely infected by staff and other animals will be tested as well.
