Here you can see the PVC 1" supports I use to keep the grids from bowing in. It works well to stabilize the cage and allows an open floorplan for running.
Thanks for the compliments on my himi texel girl. She's a sweetheart. To keep the supports from being knocked down, they are taped to the bottom coroplast. The top part is secured by the grids (I cut small grooves in the PVC pipes to hold them in place).
