Chronic kidney disease is the leading cause of death in older cats, and welfare-focused management significantly extends quality life expectancy.
CKD causes progressive welfare compromise through nausea, inappetence, dehydration, and declining energy. Many cats tolerate early CKD well with dietary management and fluid support. Regular monitoring allows medication and dietary adjustments to maintain welfare as disease progresses. The quality versus quantity of life decision becomes increasingly important in advanced CKD — maintaining an acceptable quality of life is the central welfare objective, not extending life at any cost.
