I got a tarp at a discount store and let them have their floor time on that, and they're contained on that tarp with a box worth of grids ziptied together. I do put a litter box in their pen with them. No way would my boars ever head all the way back to their cage even if they could, but they will make for a litter box or a hay box about 3/4 of the time, so I don't always have to do more than shake the tarp off outside.
