Hi, I am currently building and expanding my piggie cage. It was a 2x3 and is now a 2x4 and will have a 2x2 loft on it. I bought coloplast and the bottom is done. I need to get some more for the loft but don't really need another 4' x 8' peice....there is a 2' x 4' size I can buy bit it isn't wide enough for 2 grids. Is there anyway I could buy two of this size and join them together to fit the loft?
