Well, I just made my first attempt at building a C&C cage, and I don't know how you all do it. I have gone through the photo galleries here and all of your cages look so nice, so I assumed it wouldn't be that difficult. All I'm shooting for right now is a single level 2x6 with a lid. I measured, hooked the cubes together, cut and scored and taped the Coroplast, and went to drop the Coroplast box inside the cubes and guess what? The Coroplast bottom is way to big! Now my Coroplast is all mangled and taped together, and I still can't get it to fit inside the cubes. I'm giving up for the night, hopefully I can figure something out with it tomorrow.
