Chronic kidney disease is the most common cause of death in senior cats. Early detection and careful management can significantly extend comfortable life and maintain quality of life for affected cats.
Cats with CKD experience nausea, weakness, and the effects of toxin accumulation as kidney function declines. Without management, these symptoms worsen progressively and cause significant suffering. With appropriate management — renal diet, subcutaneous fluid support, phosphate binders, anti-nausea medication, and blood pressure control — many cats maintain good quality of life for years after diagnosis. Key welfare indicators to monitor include appetite, body condition, activity level, and willingness to engage socially. Regular veterinary monitoring allows treatment adjustments as the disease progresses. End-of-life decisions should focus on quality rather than quantity of remaining life.
