Has anyone used plexiglass or a similar see-through material on the sides of the cage? The only bummer about C&C cages is that you can't see through the coroplast. If you have - what did you use and how did you do it?
I have plexiglass on parts of one of my cages to keep the girls from biting the grids when they want my attention. I got my mom to drill holes in it (slowly, this stuff cracks easily!) and then I ziptied it to the grids. But, I can't think of a clever/easy way of using plexi in place of coroplast without ending up with a cleaning nightmare.
