actually it is supposed to be 2x3 for 1 and 2x4 for 2 piggies......u add one or two grids to every piggie u put in there....but i guess it depends on the pigs, ur pigs probably really like the 2x3...........I REALLY like ur cage though!!!!!!
(by the way i wasn't tryin to be mean, sorry if it sounded like i was)
