When cats have damage to kidney tissues, the kidneys cannot perform as well as before. The condition is not reversible, but progression may be slowed. Dietetic 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 nourish the gut microbiome to help support 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 tuna and has an irresistible taste that your cat will love. In fact, Prescription Diet k/d is clinically proven nutrition to improve & lengthen quality of life.

How it works:

  • Controlled phosphorus & low sodium, enriched with omega-3s from fish oil
  • ActivBiome+ Kidney Defense nourishes the gut microbiome to support kidney health
  • Enhanced Appetite Trigger (E.A.T.) Technology for cats
  • High levels of essential amino acids and L-carnitine

How it helps:

  • Helps protect vital kidney function
  • Helps manage the changes in the gut microbiome caused by impaired kidney function
  • Stimulates appetite & increases food intake
  • Supports natural ability to build and maintain muscle mass
  • S+OXSHIELD: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals
