How do you set up C&C cages?

I know the basics on how to make it, but can you use fleece instead of cedar? Ive seen it b4 and it looks nice. You can have their play area, and then their kitchen area has cedar in it. But if you have fleece do you still need coroplast? Also where do you get coroplast and fleece? And also, where do you get the wire tie things, because i heard the connectors dont work that well. I kno you get the grids at target, but i dont kno where to get everything else. I want it to look really cool. Also how do you clean it? Is it harder or easier? O ya, and how do you make it 2 levels? I really want to do that too. It would be great if you gave me a link to a good website with instructions and ideas. thanks =)
