Hi! We are thinking of building a C&C cage but there are no sign shops around here. Is there other substitutions? Plastic or maybe even Alphabet and numbers foarm boards or something. Please, I need ideas quickly, I want to start building right away. I wish I could get some pics of my Guinea Pigs but I cannot. So Carly and Sandy say Hi and hope you can help me find other substitutions for Coroplast so we(Carly and Sandy) can have a lot of space to run and play with each other without being cramped in these little, tiny Pet store cages.
