Healthy kidneys are vital not only for people but for big cats too.

On World Kidney Day, observed annually on March 12, the global animal welfare organisation FOUR PAWS is drawing attention to a lesser-known but critically important topic: kidney health in non-domestic felines. While chronic kidney disease (CKD) is widely recognised in domestic cats, the condition also affects majestic species like lions, tigers, and leopards, particularly those that have lived in captivity or endured years of inadequate care before their 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. Anatomy, genetics, viral infections, and even dental disease are suggested as contributing factors to CKD in felids, though the exact causes remain unclear.

For many of the big cats at LIONSROCK, age and past suffering significantly increase their susceptibility. Some residents arrived at the sanctuary elderly or in poor health after spending years in circuses, private keeping, or other exploitative environments without access to proper veterinary treatment.
Caring for these vulnerable animals requires immense dedication. Pirker explains the meticulous approach of the sanctuary's team: "As our big cats grow older, they depend on us more than ever. 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 within their spacious enclosures under the African sun. World Kidney Day serves as a global reminder of the importance of kidney health, and at LIONSROCK, it underscores the commitment 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," concludes Pirker. "A promise of compassion, safety and a peaceful life after rescue."
