Let's see if I can explain this..! I've been sketching on and off for two days planning a C&C cage for two boars and that's exactly what I'm looking at: a 4 x 2 with a 2 x 2 loft. Mine has to be enclosed due to one notable feline resident, but I'm thinking I'll have the two middle front grids cable-tied on the outer sides, bulldog clip them in the middle, and use them as doors. Similar thing in the loft, only using two grids on the top that open upward. When those front doors are open, I'd have easy access to half the space under the loft for piggie retrieval purposes. Maybe a thought? Pop a door in someplace on that side so you can get at them.
