When cats have damage to kidney tissues, the kidneys cannot perform as well as before, like filtering and reabsorbing nutrients. The condition is not reversible, but progression may be slowed. Therapeutic foods for kidney conditions are designed to help reduce workload on the kidneys, enabling them to function more effectively. Cats with decreased kidney function may experience loss of appetite and their food intake might decline.

Hill's nutritionists and veterinarians developed Hill's Prescription Diet k/d clinical nutrition with ActivBiome+ Kidney Defense, a proprietary blend of prebiotics shown to activate the gut microbiome to help protect kidney function. Prescription Diet k/d is also formulated with Enhanced Appetite Trigger (E.A.T) to stimulate appetite and increase food intake.

This dry food is made with ocean fish and has an irresistible taste that your cat will love. In fact, the nutrition of Prescription Diet k/d is clinically proven nutrition to improve & lengthen quality of life.

How it helps:

  • Helps protect vital kidney function
  • Helps manage the invisible changes within the intestinal tract that impact kidney function
  • Helps build muscle mass and helps maintain energy and strength
  • Stimulates appetite & increases food intake
  • S+OXSHIELD: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals

How it works:

  • Reduced phosphorus & sodium, enriched with omega-3 fatty acids
  • ActivBiome+ Kidney Defense activates the gut microbiome to reduce harmful waste products
  • With optimized levels of essential amino acids and high quality protein to help keep them strong
  • Enhanced Appetite Trigger (E.A.T.) for cats
