Hey guys, I'm about to get 2 female pigs, and my mom and I are trying to decide how to build a cage for very cheap. We love the C&C cages, but no where can we find Coroplast, or online for cheap. We were wondering if we could use sheet metal as a bottom instead of coroplast. Could it hurt them? We were thinking of Linolium, but do not know how you guys can get the sides to stay up as if a box. We would like the 2 piece idea, so we can clean the bottom of the cage and the pigs can still stay safe in the grid part as we clean. We couldn't find grids either, but found a "playpen" that has the 8, 13 inch long sides snap together we can use instead. Any help would be great!
