I am finally getting my coroplast tommorow. I am still deciding which color though. Suggestions please. I am going to get 2 4x8 sheets for my cage just incase I want to add an upper level or something like that. I also have finally come up with a cage size I like. It is now a 4x6 and it will house 4 piggies or 5. I am so happy. Yah!!!
