Feline chronic renal failure: long-term medical management.

Chronic renal failure (CRF) is one of the most common illnesses of geriatric cats. Common clinical signs include polydipsia, polyuria, decreased appetite, weight loss, and vomiting. Although CRF is incurable, it may be possible to delay the progression of the disorder by feeding an appropriate diet and by monitoring and normalizing (if possible) several parameters, including blood pressure, serum phosphorus and potassium levels, parathyroid hormone levels, and proteinuria.
