Cat Chronic Kidney Disease: Welfare Management

Chronic kidney disease is the most common cause of death in older cats, and welfare-focused management can extend quality life years while minimising suffering.

Key Facts

Chronic kidney disease (CKD) affects over 30% of cats over 15 years of age.
Early stages are often asymptomatic; annual blood and urine testing from age 10 enables early detection.
CKD causes nausea, lethargy, weight loss, increased drinking and urination, and ultimately uraemia.
Dietary phosphorus restriction and adequate hydration are the most evidence-based interventions.
Subcutaneous fluid therapy at home can significantly extend quality of life in moderate to severe CKD.

Welfare Considerations

Cats with CKD experience progressive, debilitating illness that reduces quality of life over months to years. With appropriate management, many cats can maintain a good quality of life for extended periods. Key welfare interventions include dietary modification, appetite stimulants to prevent nausea-driven anorexia, phosphate binders, and owner-administered subcutaneous fluids. Regular monitoring enables timely adjustment of treatment and early recognition of deterioration requiring palliative or end-of-life discussion.

What You Can Do

Schedule annual blood and urine testing from age 10 to detect early-stage CKD.
Transition to a veterinary-prescribed renal diet as soon as CKD is diagnosed.
Encourage fluid intake through wet food, water fountains, and multiple water bowl locations.
Ask your vet about phosphate binders and other medications to slow disease progression.
Discuss end-of-life planning with your vet to ensure euthanasia before significant suffering occurs.
