FOUR PAWS reminds the public that healthy kidneys are vital not only for people, but also for rescued lions, tigers, leopards and other non domestic felines.
Bethlehem, 11 March 2026 – On World Kidney Day observed on 12 March, FOUR PAWS is drawing attention to a lesser-known but critically important topic: kidney health in big cats. While chronic kidney disease (CKD) is widely recognised in domestic cats, the condition also affects non-domestic felines such as lions, tigers and leopards, especially those that have lived in captivity or endured years of inadequate care before rescue.
“Kidneys are extraordinary organs responsible for filtering toxins, balancing hydration and electrolytes, supporting blood pressure and even aiding red blood cell production,” says Hildegard Pirker, Sanctuary Manager at LIONSROCK Big Cat Sanctuary. “When they begin to fail, the entire body feels the strain. The same is true for our big cats.”
CKD is one of the most common age‑related diseases in felines. As obligate hypercarnivores, their naturally high‑protein diet places additional metabolic demand on the kidneys throughout their lives. Research suggests that anatomy, genetics, viral infections and even dental disease may contribute to the development of CKD in felids, though the exact causes remain unclear.
For many of the big cats at LIONSROCK, age and past suffering increase their susceptibility. Some residents arrived at the sanctuary already elderly or in poor health after spending years in circuses, private keeping or other exploitative environments without access to proper veterinary treatment.
“As our big cats grow older, they depend on us more than ever,” Pirker explains. “Our veterinary team carefully monitors each individual’s condition and prepares tailored medications to support kidney function, manage discomfort and maintain appetite and hydration. We cannot reverse chronic kidney disease, but we can slow its progression and ensure every animal experience comfort and dignity.” Thanks to this daily care, many senior big cats continue to enjoy an active, enriched life, exploring their spacious enclosures, engaging with enrichment, and resting peacefully under the African sun.
World Kidney Day serves as a global reminder of the importance of kidney health, and at LIONSROCK it highlights the dedication required to care for rescued animals who rely entirely on humans for their wellbeing. “At FOUR PAWS, every measured dose of medication is part of a promise,” says Pirker. “A promise of compassion, safety and a peaceful life after rescue.”

Fun South African Fact: Vilakazi Street in Soweto has been home to two Nobel Peace Prize winners. A tour through Soweto will always stop at Vilakazi Street to reveal a number of heritage sites of great importance to democratic South Africa. Both Nelson Mandela and Archbishop Desmond Tutu lived here at some point in their lives. In 1984, Archbishop Desmond Tutu received the Nobel Peace Prize in recognition for his non-violent fight against the apartheid regime. Nine years later in 1993, Nelson Mandela shared the Nobel Peace Prize with then-president F.W. de Klerk as an award for their role in bringing about the peaceful end of apartheid. Nelson Mandela then went on to become South Africa’s first democratically elected president in 1994.
