Some people don't use pigloos because they're commonly a source of fighting. I use bent grids covered in fleece because of this. The grid-tunnels have two exits so the pigs can get away and more ventilation, which is important to me in the hot summer months (I have no air conditioning). I've seen people who use cuddle cups and drape fleece over the corner of the cage so the cups have a 'roof'. Pigloos aren't the only option, or the end all be all of hidey houses for pigs. It all depends on what works best for you and them.
