It contains 25 synthetic additives (so it is not all-natural), it has 3 anti-nutrients including Potato, Potato Starch, and Soybean Oil (which may interfere with the absorption of essential nutrients), and it has 1 other sketchy ingredient, Powdered Cellulose. Many consider this food to be inconvenient, because it requires clean-up.

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.
