Specially formulated for mature feeding schedules. Because an adult iguana has special dietary needs, Zilla researchers formulated a food specifically to suit a mature pet's 2-3 day feeding cycle and unique nutrition demands. Zilla food contains the added fiber a mature digestive system requires, along with a tempting mix of plant materials iguanas prefer. Consistency is carefully monitored, since iguanas cannot masticate (chew) food. The blend is topped off with essential minerals for robust growth, vivid color and good health, then packaged in a convenient screw top jar designed for eye appeal on a retail shelf.
