Hill's Prescription Diet k/d Kidney Care is a veterinary wet food formulated specifically for cats diagnosed with chronic kidney disease. Available in a chicken and vegetable stew, it's prescribed for ongoing dietary management — not a supplemental add-on, but typically the primary meal for cats managing a renal diagnosis.

The k/d formula is clinically developed to reduce the burden on compromised kidneys by controlling phosphorus and sodium intake. Protein is managed carefully: sufficient to maintain lean muscle mass, but moderated to reduce nitrogenous waste that damaged kidneys struggle to process. The stew format adds meaningful moisture to the diet, which supports hydration — a particular concern for cats with kidney disease, who are prone to chronic dehydration.

Kidney disease is one of the most common conditions in older cats, and dietary management is consistently a first-line treatment tool. k/d has a long clinical track record, which is why it's frequently the initial dietary recommendation when a renal diagnosis is made.
