Chronic Kidney Disease and Cat Welfare

Chronic kidney disease is the leading cause of death in older cats and a major source of chronic welfare harm.

Key Facts

CKD affects an estimated 30-40% of cats over 15 years of age
Early CKD causes few clinical signs, so many cases are diagnosed late
Subcutaneous fluid therapy at home significantly improves quality of life for cats with CKD
Dietary management with reduced phosphorus improves survival in CKD cats
Regular blood and urine monitoring enables early detection and staging of CKD

Welfare Considerations

Chronic kidney disease causes progressive nausea, weakness, dehydration, and loss of appetite in affected cats, significantly reducing quality of life. Because early signs are subtle, many cats present with advanced disease. Regular monitoring of older cats, early dietary intervention, and appropriate management of clinical signs can significantly extend comfortable life and maintain welfare in CKD-affected cats.

What You Can Do

Schedule annual blood tests for cats over 8 years to screen for early CKD
Begin phosphorus-restricted diet at the first sign of renal insufficiency
Learn subcutaneous fluid administration to support cats with advancing CKD
Monitor appetite, weight, and hydration status closely in CKD cats
Discuss quality of life and prognosis honestly with your vet as the disease progresses
