Plastic Bin Ferret Litter Box
Make a litter box that has a large area for your ferrets! Get a plastic storage container that is the ideal size for your ferrets. Draw the outline for the doorway on the front wall of the container, drill holes along the lines you drew, then saw along the lines through the holes. Sand the cut edge of the plastic smooth or cover it with pieces of duct tape to protect your ferrets from any sharp edges.
