In advanced feline chronic kidney disease, which electrolyte abnormality is commonly observed?

In advanced feline chronic kidney disease, potassium balance tends to become low. Damaged kidneys lose some ability to conserve potassium, and many cats with CKD have reduced dietary intake of potassium due to anorexia. Additionally, ongoing urinary losses from the diseased kidneys contribute to lower potassium levels. This combination makes hypokalemia the most common electrolyte abnormality in these cats and it helps explain why supplementing potassium is often a key part of management. Clinically, low potassium can worsen weakness, reduce appetite, and impair overall energy, so addressing it can markedly improve quality of life and response to therapy. While hyperkalemia can occur in some CKD scenarios, it is not the typical pattern seen in advanced feline CKD. Hypercalcemia and hyponatremia are less characteristic of this specific situation.
