Hey all I'm building my new pig a new cage. Since everyone in my house are video game nerds we're doing a Rainbow Road themed cage from Mario Kart. I ordered the rainbow coloured grids but I was interested in building storage area underneath the cage which I have never done before. So if I were to elevate the cage, how many cubes would be used? I'm not so much interested in dividing the bottom into different sections, just a general storage space. The rainbow box grids come 16 in a box and 10 are going to be used for the actual cage. How many more grids would I need to achieve this?
