Feline Hills kd with Ocean Fish is formulated for the Nutritional Management of Cats with Kidney Disease and Cardiovascular disease. Hills kd has reduced Sodium Chloride which helps control clinical signs associated with sodium and fluid retention (ascites/edema) and minimizes systemic and renal hypertension (primary). It also has reduced phosphorus which helps slow the progression of kidney disease. This reduced protein and increased non-protein calorie formula helps meet nutritional needs while reducing kidney workload. Its dietary buffering capacity helps counteract the tendency for metabolic acidosis, a common complication of kidney failure, to help lessen muscle wasting.
