Food sensitivity and intolerance are potentially serious problems that can result in irritated skin, coat and ear conditions or even gastrointestinal upset. Cats that have a food sensitivity or intolerance, also called adverse reactions to food, typically experience an abnormal response to the protein in the food. If your cat suffers from adverse reactions to food, it is even more important to feed the right food. Hill's nutritionists and veterinarians developed Prescription Diet® z/d® clinical nutrition especially formulated to support your cat's skin and food sensitivities. In fact, z/d is clinically proven nutrition to help avoid adverse reactions to food. -Formulated to help improve digestion & stool quality -Helps eliminate food-related causes of skin irritation -Promotes a healthy skin barrier -S+OXSHIELD™: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals -Helps support a healthy immune system INGREDIENTS: Brewers Rice, Hydrolyzed Chicken Liver, Rice Protein Concentrate, Powdered Cellulose, Soybean Oil, Coconut Oil, Chicken Liver Flavor, Calcium Carbonate, Lactic Acid, Potassium Chloride, Calcium Sulfate, Glyceryl Monostearate, Dicalcium Phosphate, L-Threonine, DL-Methionine, L-Lysine, Choline Chloride, vitamins (Vitamin E Supplement, L-Ascorbyl-2-Polyphosphate (source of Vitamin C), Niacin Supplement, Thiamine Mononitrate, Calcium Pantothenate, Vitamin A Supplement, Pyridoxine Hydrochloride, Biotin, Riboflavin Supplement, Vitamin B12 Supplement, Folic Acid, Vitamin D3 Supplement), Taurine, Iodized Salt, Potassium Citrate, L-Tryptophan, minerals (Ferrous Sulfate, Zinc Oxide, Copper Sulfate, Manganous Oxide, Calcium Iodate, Sodium Selenite), Mixed Tocopherols for freshness, Natural Flavors, Beta-Carotene.
