It contains 28 synthetic additives (so it is not all-natural), it has 1 anti-nutrient, Soybean Oil (which may interfere with the absorption of essential nutrients), and it has 6 other sketchy ingredients, including Pork Liver Flavor and Natural Flavors.

Warning Due to this being a grain-free food that contains legumes or potatoes this Hill's Prescription Diet recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
