Cat Chronic Kidney Disease: Managing a Common Senior Cat Condition

Chronic kidney disease is the leading cause of death in cats over 10 years old, requiring careful management to maintain quality of life through dietary and medical intervention.

Key Facts

CKD affects approximately 30-40% of cats over 15 years old
Early stages are often asymptomatic; diagnosis requires blood and urine testing
Phosphorus restriction is one of the most important dietary interventions
Subcutaneous fluid therapy given at home can significantly improve wellbeing
Some cats with well-managed CKD live for years with good quality of life

Welfare Considerations

CKD causes nausea, dehydration, and lethargy that profoundly affect a cat's quality of life. Early detection through regular senior blood panels allows intervention before symptoms worsen. Dietary management must be palatable - a cat refusing food does more harm than a less-than-perfect diet. Monitoring appetite, weight, and behaviour at home helps caregivers detect deterioration early.

What You Can Do

Schedule annual blood and urine testing for cats over 7 years old
Learn to give subcutaneous fluids at home - many owners manage this successfully
Transition to kidney-supportive diets gradually to maintain food acceptance
Monitor your cat's drinking, appetite, and weight weekly
Work with your vet to set clear quality-of-life goals and thresholds for intervention
