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. •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 INGREDIENTS: Chicken, Brewers Rice, Whole Grain Wheat, Corn Protein Meal, Chicken Fat, Egg Product, Wheat Gluten, Pea Protein, Brown Rice, Flaxseed, Chicken Liver Flavor, Dried Beet Pulp, Soybean Oil, Fish Oil, Lactic Acid, Calcium Sulfate, L-Arginine, Potassium Citrate, Betaine, Whole Grain Oats, Choline Chloride, Calcium Carbonate, Fructooligosaccharides (FOS), vitamins (Vitamin E Supplement, L-Ascorbyl-2-Polyphosphate (source of Vitamin C), Niacin Supplement, Thiamine Mononitrate, Pyridoxine Hydrochloride, Calcium Pantothenate, Riboflavin Supplement, Vitamin A Supplement, Biotin, Vitamin B12 Supplement, Folic Acid, Vitamin D3 Supplement), Taurine, Potassium Chloride, DL-Methionine, Iodized Salt, L-Carnitine, minerals (Ferrous Sulfate, Zinc Oxide, Copper Sulfate, Manganous Oxide, Calcium Iodate, Sodium Selenite), L-Threonine, Mixed Tocopherols for freshness, Natural Flavors, Beta-Carotene.
