I have two males who do not get along at all, but it is important to me, as well as them, that they be close to each other. I had more than enough grids to make two separate 2x3 cages, so I ordered two bases. Their cages are completely connected, but extra grids, down the middle, act as a barrier, so they both feel safe and comfortable, but can still interact when they want to. I love the coroplast colors I chose, but I also love the fact that I can order other colors when I want or need to, and it won't break the bank. Their room is so bright and cheery now! The bases are literally a simple snap to put together and everyone who meets my piglets or sees pictures compliments their home, the size, the uniqueness, and how happy they are. I love my boys and I love seeing them happy! :) Shipping was also super fast!
