I am so excited, my boys moved into their first C&C cage today!! I have no experience putting one of these together, so go easy on me please. *ducks* hee hee. It's a 2x5, and I have 2 boars. I left 3 grids out of the back, because it's RIGHT against the wall, and the coroplast on that side is 11 inches tall. So that gave me a few extra grids to mess with. I put two of them on top on the left end where their cuddle cups are, and I cover up the grids with a fleece blanket. Gives them a little hiding place to feel safe. I hope I did a good job for my boys!!
