Great cage. I used some 7 inch tall stakin shelves from Kmart to set my cage up off the floor. It looks like you still have room for something like that if you want the bottome cage up off the floor. The shelves were plastic and cost $3.99 each (I used 3). Just a suggestion.
I love black C&C cages. They look so much nicer than the white and coloured coroplast cages I think! I am in the process of building my piggies two new 2x4 cages with black coroplast.
