I had a midwest cage and when i adopted another pig i bought a second and just kind of rigged it together so it is one huge cage. So no i don't have the C/C grid things.
I figured the space was more important so i moved them back down to the floor.
So i have three pigs. I had them on the floor but they seemed so stressed because of people walking by. So i put them on a table i don't really use. Which is a smaller space. Well they started fighting because of the smaller space but they seemed happy that they didn't have people towering over...
