Feline Chronic Kidney Disease Welfare: Long-term Management

Chronic kidney disease (CKD) is the most common disease of senior cats, affecting over 30% of cats over 15 years. Welfare-focused management can provide years of good quality of life.

Key Facts

CKD affects an estimated 30-40% of cats over 15 years old
The IRIS staging system (1-4) guides treatment intensity
Early-stage CKD may be managed with diet alone — phosphate restriction is central
Hypertension secondary to CKD causes retinal haemorrhage and blindness if untreated
Subcutaneous fluid administration at home can substantially improve welfare in moderate CKD

Welfare Considerations

Cats with well-managed CKD can maintain good quality of life for years. The welfare priority is preventing the complications of CKD — hypertension, anaemia, uraemia and hyperphosphataemia — rather than simply treating the disease. Owner-administered subcutaneous fluids improve hydration status and reduce uraemic symptoms substantially. The welfare goal is maintaining a cat in a comfortable, engaged state rather than maximising survival time at the cost of quality of life.

What You Can Do

Screen cats over 10 years annually for CKD with SDMA and creatinine blood tests
Learn to administer subcutaneous fluids at home with veterinary guidance
Use renal diets with restricted phosphorus as recommended by your vet
Monitor blood pressure every 6 months in cats with any-stage CKD
Maintain honest quality of life assessment to guide treatment escalation decisions
