Excessive urinary potassium loss was diagnosed in 7 cats with persistent hypokalemia and high serum creatinine concentrations. Renal tubular acidosis (proximal or distal) was not evident in the affected cats. Plasma aldosterone concentrations and plasma renin activities in affected cats were not significantly different from control values. Potassium depletion and hypokalemia were attributed to the combined effects of decreased dietary potassium intake and excessive urinary potassium losses. It was concluded that increased urinary potassium excretion may represent a basic response to renal dysfunction in cats. Data suggested that dietary potassium supplementation improved renal function in most cats in this study.
