OK so I was at a party and I was talking to my cousin about guinea pigs..like my usual conversations Anyway we were talking about cages, and she said that instead of coroplast, she uses the under the bed style storage bins! And my mind was blown! I can't believe I never thought it before! It seems like it would be pretty common but I don't hear it mentioned ever! Just wondering has anyone else thought of that or did it blow your mind too?
