Chronic Kidney Disease in Cats

Chronic kidney disease is one of the most common conditions in older cats and causes significant suffering that can be reduced through early detection and management.

Key Facts

CKD affects approximately 35% of cats over 15 years old
Early stages often have no obvious symptoms, making routine blood testing essential
Cats with CKD experience nausea, reduced appetite, weight loss, and eventually uraemia
Phosphorus restriction in diet significantly slows disease progression
Subcutaneous fluids given at home can greatly improve quality of life in moderate to severe CKD

Welfare Considerations

CKD causes progressive suffering through nausea, malaise, and ultimately uraemic poisoning. The insidious onset means many cats live with early-stage disease causing subclinical suffering for months before diagnosis. Early detection through annual blood screening from age 7 allows intervention that can add years of good quality life. End-of-life decisions must weigh quality of life carefully; euthanasia is often the kindest option in severe disease.

What You Can Do

Ask your vet about blood screening for kidney disease in cats over 7 years old
Follow veterinary dietary recommendations if your cat is diagnosed with CKD
Learn subcutaneous fluid administration if recommended by your vet
Monitor appetite, weight and thirst as early CKD indicators
Discuss quality of life assessment with your vet throughout disease management
