Chronic kidney disease (CKD) is one of the most prevalent conditions in older cats, affecting welfare profoundly. Early detection and appropriate management can significantly extend quality of life.
CKD in cats progresses gradually, and many cats live with significant kidney dysfunction before obvious symptoms develop. The welfare implications are substantial: nausea, lethargy, dehydration, and eventually severe metabolic disturbance affect quality of life. Early detection through annual blood tests in middle-aged and older cats allows interventions that slow progression and maintain quality of life. The welfare-conscious approach involves regular monitoring, prompt treatment of complications, and honest quality-of-life assessment as the disease progresses — with willingness to provide euthanasia before the terminal phase causes prolonged suffering.
