Chronic kidney disease is the most common serious illness in senior cats. Staged management maximizes quality and length of life.
CKD has a profound impact on feline quality of life as it progresses, causing nausea, hypertension, anemia, and uremic toxin accumulation. Early detection through annual bloodwork in senior cats enables intervention before clinical signs appear and significantly extends comfortable, high-quality lifespan. Dietary transition to renal diets must be gradual and palatability-focused — a cat that refuses its renal diet is worse off than one eating a non-renal diet. Managing concurrent conditions including hypertension, anemia, and dental disease is equally important. Owners should be educated to recognize signs of deterioration and supported with quality-of-life scoring tools to guide difficult end-of-life decisions. Adequate hydration support, often through wet food or fluid therapy, is central to long-term management.
