Sorry, I tried to edit this in but I guess I was a little too late

Until I was able to find choroplast for a decent price, I used scrap linoleum. I found a roll at Home Depot for about $5. I punchd holes in the sides with an awl and zip tied them up on the grids to make a proper side since linoleum isn't as sturdy or easy to work with as the choroplast. But it worked well for me for about 6 months. I also used a scrap piece laid out flat on the floor with grids on top of it as a quarantine cage. It worked well, too, though not as well as tying it up to the sides of the grids.
