C&C Cage C&C stands for cubes and coroplast and is a fantastic way to make a very sturdy and cost effective cage. If you were to build Barley's cage alone (3 X 2 grids) it would cost you less than $100 including the coroplast. My entire structure is comprised of three boxes of cubes (each box containing enough grids to make 6 cubes) and two (or three?) large sheets of coroplast.
One pack of cubes (containing enough grids to make six cubes) is $29.99 at Home Depot A large sheet of coroplast is roughly $29.99 as well
