A: Thank you for taking interest in our recipe. The ONE Urinary Tract Health Formula Natural Chicken Flavor Dry Cat Food features real chicken as the first ingredient. Helps maintain urinary tract health by reducing urinary pH and providing low magnesium blended with supports for strong muscles, including a healthy heart. While this formula offers several benefits, we always recommend consulting with your trusted veterinarian to ensure it's suitable for your cat, especially if you plan on mixing it with other kibbles. The number of calories needed varies, depending upon the pet's age, activity level, and metabolism. It is important to remember that the feeding charts on the packages are only a guideline, so the amount that works best for a particular pet may be slightly above or below the ranges listed on the bag.
