Feline kaliopenic polymyopathy/nephropathy syndrome.

The prevalence of hypokalemia in cats has probably been underestimated until recently. Like many other "contemporary" diseases, this syndrome is probably not new; however, it is now more easily recognized because of the identification of associated dietary and disease risk factors, clinical signs, and laboratory abnormalities, which have been linked to the expected pathophysiology of potassium depletion in the cat.
