I saw in my Google News that one of the female lions, Zuri, passed away at the Topeka Zoo. If I remember correctly, she was the lioness who grew a mane after her male companion's passing a few years ago, but might be confused.
Facebook has some good information:
"Over the past few months Zuri had been closely monitored due to the risk of kidney failure, a common ailment for geriatric cats of her age. A month ago, Zuri started experiencing increased symptoms, which accelerated in the past few days. Yesterday, Zuri was anesthetized for a veterinary exam that confirmed suspicions of kidney failure. The difficult decision was made to humanely euthanize her.
'Zuri was truly a lioness in charge, and her strong and independent personality was evident to all who knew her,” says Shanna Simpson, Animal Curator. “ Zuri has always been a star in our hearts and we will miss her tremendously'
At 19 years old, Zuri and her sister Asante had surpassed the median life expectancy for African lions.
'Asante is facing her own age-related challenges,' continued Simpson. 'Especially because of the bond she shared with her sister, we will be extra attentive to Asante’s needs for the foreseeable future.'
The unfortunate passing of Zuri comes after the Topeka Zoo announced the arrival of 4-year-old male lion, Tatu on April 23.
'We are responsible for the wellbeing of the animals in our care through the entirety of their lifespan', said CEO Brendan Wiley. 'The addition of Tatu was a step to establish our next pride, knowing that our time with both Zuri and Asante would be limited. While we are saddened by losing Zuri, we know she made an incredible impact on our staff and guests during her time here.'"
According to other articles, Zuri stopped eating on Tuesday.
This is most unfortunate for Asante, losing her last companion, but I hope she remains healthy for a long time still.
