Chronic Kidney Disease in Cats: Welfare Management

Chronic kidney disease is the most common serious illness of older cats, requiring long-term management to maintain quality of life.

Key Facts

Chronic kidney disease affects an estimated 30-40% of cats over 15 years
Early disease is often asymptomatic, making routine blood and urine testing essential for detection
Signs include increased thirst and urination, weight loss, reduced appetite, and lethargy
Dietary phosphorus restriction significantly slows progression in cats with confirmed CKD
Subcutaneous fluid therapy at home provides relief from dehydration and extends quality life

Welfare Considerations

Cats with CKD experience a range of welfare-compromising symptoms including nausea, dehydration, lethargy, and uraemic toxin accumulation. Nausea from uraemia reduces food intake in a self-reinforcing cycle that accelerates weight loss and muscle wasting. Early detection through regular blood testing allows management to begin before clinical signs appear, substantially improving prognosis and welfare outcomes. Home fluid therapy, when owners are willing and able, provides the most significant welfare benefit by treating dehydration without repeated stressful clinic visits. End-of-life decisions for cats with advanced CKD require careful monitoring of quality of life indicators.

What You Can Do

Schedule blood and urine testing annually for cats over 7 years old
Learn the early signs of CKD including increased thirst and weight loss
Discuss phosphorus-restricted prescription diets with your vet at diagnosis
Consider learning home fluid administration for cats with moderate to advanced disease
Use quality of life assessment tools to monitor welfare and inform end-of-life decisions
