We decided to get the cage one size up, in case we ever decide to have 3 piggies. Our 2 girls love having so much space for themselves, and the coroplast is so much easier to keep clean than traditional pet store cages. We got the 10 inch back coroplast wall (to protect our walls), but didn't anticipate that would give us a lot less grid space to hang goodies, just FYI. We chose the dark green base with white grids, and we love the way it looks! Having the open top lets us really enjoy the piggies and feel more connection to them. We had some issues with shipping (not GPCC's fault!) but customer service was understanding and responsive. The YouTube instruction videos were super helpful for assembly! Highly recommend!
