In November, my colleague and friend Anthony Nielsen, a head carnivore keeper at Chicago’s Lincoln Park Zoo, graciously offered me, my sister and my four-year-old niece a behind-the-scenes tour of the zoo’s famed Lion House.
On prior visits to the Lincoln Park Zoo, I always visited the Kovler Lion House, a historical landmark in its own right. I always thought that the building’s feline residents were deserving of some kind of entitlement by mere association with the regal edifice at the world renowned zoological park.
Sadly, it would be the first and last time we met “The Queen.”

Marta, an adopted melanistic leopard, was the first to greet us as we walked behind the big cat exhibits. Anthony called for her, and she suddenly appeared before us. As he shared Marta’s story, I couldn’t take my eyes off her. She was remarkable, even if she had not been a stand-out for longevity. There was something about her which in retrospect explains much about her nickname.
When I learned of her passing this week, I knew exactly who the Chicago-area newspapers were talking about. Every animal ambassador is special, but some individuals are more remarkable than others, and not just to the people who work with them day in and day out.
Lincoln Park’s Zoological Manager, Mark Kamhout reflects that, “Marta was known by many guests of Lincoln Park Zoo and was a wonderful, playful and very gentle cat. Despite being one of the oldest cats at the Lion House, Marta always was very engaging with people and especially enjoyed being scratched by her keepers with either a long handled brush or cardboard tube.”
Geriatric Animals in Zoos
There are a lot of geriatric animals in North American zoos. The irony was that my last visit to Chicago was for a conference on geriatric care of humans. I was invited to contribute some of my background working with an aging population of zoo animals and had coincidentally just met Marta.
The attendees at the conference were most impressed with the level of thought that goes in to caring for geriatric animals kept in captivity. Marta was a recipient of medical intervention on several occasions, not unlike the case for so many older animals that well exceed their expected age in the wild. Sometimes they reach over twice the expected age of their wild counterparts.
In Marta’s case she exceeded her expected lifespan by about five years. Cats can survive for several years with renal failure, but as with Marta, there is no cure and she ultimately succumbed to the advanced stages of kidney disease. A difficult decision to euthanize her was agreed upon.
I extend my condolences to Marta’s caretakers and the patrons of the Lincoln Park Zoo.
Marta was 20 years old and lived at Lincoln Park Zoo nearly her entire life. She was brought to the zoo in 1992 after wildlife officials confiscated her from being kept illegally in a private home. The median life expectancy of leopards in zoos is approximately 14 years, according to Lincoln Park Zoo.
