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, and taking action early can be beneficial. 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 Early Support clinical nutrition for early protection of a cat's vital kidney function and to encourage eating for strength and energy. It's formulated with ActivBiome+ Kidney Defense, a proprietary blend of prebiotics shown to activate the gut microbiome to help protect kidney function. This dry food is made with chicken and has an irresistible taste that cats love.

Acting early with the nutrition of Prescription Diet k/d Early Support can help improve quality of life and lengthen the relationship with your cat.

How it works:

  • Avoids excess phosphorus and 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

How it helps:

  • Early support of 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
  • Encourages eating for energy and vitality
  • S+OXSHIELD: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals
