What are the stages of kidney disease in cats?

Cat kidney disease is staged 1-4 using the IRIS system. Stage 1 shows no clinical signs with creatinine 5.0 mg/dL. SDMA values provide earlier detection.

What is SDMA in cats and why does it matter?

SDMA (symmetric dimethylarginine) is a kidney biomarker that increases earlier than creatinine in cats with kidney disease. SDMA can detect kidney function loss when only 25% of function is lost, versus 75% for creatinine. This allows earlier intervention and potentially better outcomes.

How long can a cat live with CKD?

Cat CKD survival varies by stage. Cats diagnosed at Stage 2 may live 3+ years with proper management. Stage 3 cats often survive 1-2 years. Stage 4 prognosis is typically months, but individual cases vary. Early detection, diet modification, hydration support, and regular monitoring significantly impact outcomes.

What should I feed a cat with kidney disease?

Cats with CKD benefit from prescription renal diets that are lower in phosphorus and protein, with added omega-3 fatty acids. These diets are clinically proven to extend survival and improve quality of life. Always transition gradually and ensure adequate calorie intake. Your veterinarian can recommend specific brands.

What are early signs of kidney disease in cats?

Early CKD signs in cats include increased thirst and urination, weight loss despite normal appetite, occasional vomiting, mild dehydration, and decreased energy. Unfortunately, cats often hide illness well, so regular senior bloodwork (annually after age 7) is crucial for early detection.
