Chronic kidney disease (CKD) is the most common cause of death in older cats. Managing CKD requires careful nutrition, hydration support, and quality of life assessment to maximize welfare in affected animals.
CKD welfare management is one of the most important long-term welfare challenges in senior cat care. As the most common cause of death in older cats, CKD affects millions of animals — but the welfare trajectory from diagnosis to end-of-life spans a wide range depending on disease stage and management quality. Early-stage CKD cats that are asymptomatic can maintain excellent quality of life for years with dietary management and monitoring. As disease progresses, nausea, reduced appetite, weight loss, dehydration, and hypertension cause increasing discomfort that requires active management. Subcutaneous fluid administration at home — initially intimidating for owners — is highly effective at maintaining hydration and significantly improving quality of life in later stages. Anti-nausea medication, phosphorus binders, and antihypertensive drugs address specific welfare-compromising symptoms. Quality of life assessment using validated tools helps owners and vets make timely, compassionate end-of-life decisions rather than prolonging suffering.
