Castor & Pollux Natural Ultramix Chicken 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 15 synthetic additives (so it is not all-natural), it has 3 anti-nutrients including Potatoes, Potato Starch, and Peas (which may interfere with the absorption of essential nutrients), and it has 3 other sketchy ingredients, including Natural Flavor and Garlic. 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 Castor & Pollux recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
