We upgraded to a 2x6 c&c cage when we got our third pig and decided to add a loft shortly after that. None of them will use the loft. I don't think they have an aversion to lofts since our older two used the one in the old cage frequently. I've tried putting food and toys up there and tried luring them up the ramp with treats. If I put them in it after lap time they just poke around for a minute or so and then head back down. Anyone have ideas on how I can get them to use it or should I just throw in the towel?
