CKD is the most common serious disease in senior cats. Staged management that matches intervention intensity to disease stage optimizes quality of life throughout the disease course.
Feline CKD management requires balancing disease progression with quality of life at each stage. Early-stage CKD cats often feel well and require only dietary modification and monitoring — unnecessary intervention reduces quality of life without benefit. As disease progresses, the welfare balance shifts toward more active management: phosphorus restriction, fluid supplementation, hypertension management, and nausea control become important for maintaining comfort. Advanced CKD cats may feel profoundly unwell from uremic toxin accumulation — the welfare goal at this stage is comfortable palliation rather than cure. Home subcutaneous fluid administration, often taught to owners, significantly reduces the burden of clinic visits and maintains hydration comfortably. The endpoint-of-life decision for CKD cats requires ongoing quality-of-life assessment rather than waiting for crisis.
