I've got my new C&C cage built and am eager to get my piggies in their new home. However, I followed the instructions, but there's a gap in between the cloroplast and the grids. When the taller back of the cloroplast box is pushed all the way back to the grids, there is an almost 3 inch gap in the front. Is it supposed to be this way? I emailed Sue at C&C and am waiting a response, but thought I'd post here to see if you all could help as well.
