I was wondering if I could use foam board instead of coroplast, as show here:
Elmer's White And Black Foam Boards White 40"W x 60"L Foam at Off
I am trying to get some coroplast tonight with my mom, and if that doesnt work, we might go and get some from a sign store, but I was wondering if I could use this because I saw this in Office Max last night and it was the right size for my 2x3 cage. I dont really think it will work, but if there is a way I can protect the sides from chewing could you please suggest it?
