Hello! I have a two layer C&C cage, and each layer is 2x4 grids with a ramp connecting them. I currently have a neutered, single male in the cage, but I want to make a herd of him and some girls. He has been with guinea Pigs before, so I know he is okay with some. I was just wondering: will four piggies fit in my cage? In total the two layers an 2x8 cage, so isn't that big enough?
