Introduce your bird to foraging with our Creative Foraging Systems Horizontal Holder. The durable polycarbonate horizontal foraging box holder fastens to the side of the cage with the universal bracket. Please note that this is the holder ONLY and does not include the chipboard compartment inserts. If you would like both, please purchase our starter kit, or we recommend buying our Creative Foraging Refills. The Creative Foraging Systems Horizontal Holder comes in two sizes, small and large.
