Chronic kidney disease affects the majority of cats over 15 years old and significantly impacts quality of life. Evidence-based management can extend life and maintain good welfare for affected cats.
Feline CKD is the leading cause of death in senior cats and a major welfare challenge for the cats and owners affected. The insidious nature of the disease — cats show no obvious symptoms until 75% of kidney function is lost — means early detection requires proactive screening. Management involves dietary change, fluid support, blood pressure control, and management of secondary complications. Well-managed CKD cats can maintain good quality of life for months to years beyond diagnosis. However, management requires owner commitment and significant veterinary investment. Quality of life assessment at regular intervals ensures treatment continues to serve the cat's welfare rather than prolonging life at the expense of comfort.
