I just ordered two sets of NIC cubes on Ebay yesterday. The Cubes themselves were cheap, but the shipping!! Whoah.
(Shipping from America to Norway…).
My mother-in-law actually has a few spare cubes from when she baught them a couple years ago, when ONE store in Noway used to have them
So I’m going to use those aswell, I think I’ll have about close to 40 cubes total, and if my math is correct, I will need 36. I’m planning on making a 3×2 cubes wide, 3 cubes tall cage, with 3 levels. I think this is sufficient seing that Bosse is free range whenever we are home, and when we are not, he has a pen to run around in connected to the cage, so he will never be locked in the cage 
My question is, how have you arranged with flooring and carpets etc in your NIC cages? I have seen a few where the bottoms are made out of plywood and wrapped in a carpet? What kind of carpets have you been using?
I would really like your opinion on this! Thanks
