Photobucket is acting all crazy right now, but the picture I was going to post is actually already shown on the top of this page so let me try and explain the best that I can.
My girls cages are 2 x 5 and I used a sheet of thin wood under them and attached that to the cage to be able to slide that whole section in and out so I could reach the back section for easy cleaning. When I had gotten the three girls (Emma, Rosa, and maggie) I was hoping that they would get along with the larger herd, but Emma was being a problem. My plan at that time though was move the whole cage forward one grid and take out the front, side panel to allow access into that cage. I always make my kitchen openings to get in one grid wide anyways to help keep the stuff in the kithen and not on the fleece.
Does that make any sense?
It would be like this, but the panel above the green bed would be the opening to the kitchen. (notice in the back corner you can see the carpet where the cage is not there).
Your kitchen opening would look like this. You would need to support the grid holding the cage. I just cut a grid and used the small piece and added another connector to support the weight. (shown in picture)
Than you would have no back corner to try and clean or catch pigs. I am only 5'2" and can reach easily to clean the cages and play with them.
