ZuPreem Natural is a nutritious diet designed to meet all the established nutrient requirements of Cockatiels, Quaker Parakeets, Ringneck Parakeets, Meyer's Parrots and other small parrots. ZuPreem Natural is an extruded diet, which means that it is more thoroughly cooked than a traditional pelleted food. The premium ingredients are cooked to increase digestibility thus allowing more nutritients to be utilized by your bird. Each nugget is made from the same formula and is nutritionally balanced, promoting better health. ZuPreem Natural has controlled iron content (less than 80 ppm) and may be good for species predisposed to iron-storage disease.
