We originally had two pigs in an alternative C&C, approximately a 2X4 sixe. After Sophie's cagemate died, we adopted three girls from a shelter. Currently, we have two in the original cage, and two in a 2x4 c&C cage. I would like to be able to put them all together, but am not entirely sure how to do this. Could i stack two 2x4 cages with ramps, or should i do a 3x4 with an L loft? Spacing in the room would make the 2x4 more practical, but if its much better for the girls, I think I can make a 3x4 work.
