As you can tell from the title, I'm FINALLY making a C&C cage. I already have the grids, because some friends had a guinea pig a long time ago, and they gave me their old C&C cage they had in their attic. The bottom was filthy and damaged beyond repair, but the grids and connectors are still good. I was wondering how much a large sheet of coroplast usually costs at a sign store. I also wanted to know if anyone had any tips for my piggy's new cage. Thanks in advance!
