Feline Chronic Kidney Disease: Welfare and Long-Term Management

Chronic kidney disease affects the majority of elderly cats and requires long-term welfare management balancing quality of life with treatment burden.

Key Facts

CKD affects approximately 30-40% of cats over 15 years
IRIS staging guides treatment decisions based on creatinine and SDMA levels
Renal diet reduces protein catabolism and phosphate burden on damaged kidneys
Subcutaneous fluid administration at home can significantly improve quality of life

Welfare Considerations

Cats with advanced CKD experience nausea from uraemia, reduced appetite, weight loss and lethargy. Fluid therapy reduces uraemic toxin concentrations and dramatically improves short-term quality of life, but requires home administration by owners that some cats find stressful. Dietary management reduces progression speed. Anti-nausea medication improves appetite and quality of life in cats with nausea. Palliative management of CKD with welfare as the primary goal produces better outcomes than aggressive interventions focused only on biochemical markers.

What You Can Do

Screen senior cats annually for early CKD using SDMA and creatinine
Implement renal diet and fluid therapy under veterinary guidance in IRIS stage 2-4 CKD
Support International Renal Interest Society (IRIS) CKD management guidelines
Discuss quality of life assessment for your CKD cat with your vet at each recheck
