Authority Skin is hot extruded (which means it's processed under extreme heat and pressure) and made with feed grade ingredients, which are unfit for human consumption. It contains 20 synthetic additives (so it is not all-natural), it has 4 anti-nutrients including Dried Potatoes, Dried Sweet Potatoes, and Potato Starch (which may interfere with the absorption of essential nutrients), and it has 3 other sketchy ingredients, including Dried Plain Beet Pulp and Natural Flavor.

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