For the Nutritional Management of Cats with Feline Lower Urinary Tract Disease (FLUTD) caused by struvite uroliths or urethral plugs, calcium oxalate uroliths, or feline idiopathic cystitis (FIC).

Prescription Diet c/d Multicare Feline pet food contains controlled levels of magnesium, calcium, phosphorus, and oxalate to reduce building blocks of crystals and uroliths, as well as enhanced vitamin B6 to help decrease oxalate formation and excretion in the urine. c/d Multicare Feline also generates an environment that is unfavorable for the development of uroliths due to the addition of antioxidants, Vitamin E and beta-carotene. c/d Multicare Feline is formulated to avoid excess sodium and has high levels of omega-3 fatty acids from fish oil that help break the inflammatory cycle associated with the most common causes of FLUTD.
