Chronic kidney disease is the most common serious illness in older cats, causing progressive decline in quality of life, and early detection combined with proactive management can significantly extend comfortable lifespan.
Feline CKD welfare management requires balancing disease progression control with quality of life preservation throughout the course of a condition that cannot be cured but can be managed for months to years. The welfare challenge intensifies as disease advances because treatments including dietary restriction, fluid therapy, and medications may themselves cause stress or discomfort if imposed on a cat that resists them. Welfare-positive CKD management centers on the cat's experienced quality of life rather than biochemical targets alone, recognizing that a cat that eats comfortably on a less restricted diet may have better welfare than one that refuses a prescription diet and declines nutritionally. Owner education about recognizing quality-of-life indicators, proactive pain management for associated conditions like hypertension and dental disease, and honest conversations about end-of-life timing are central to humane CKD care.
