A Target Threshold Wicker Trunk & Sterilite 66 qt plastic storage box for a hidden litter box. 1. Using wire cutters snip the wicker down the center where for the door. 2. Then snip the vertical supports, some are metal. Don't cut too many (look at the handle above door for width) a metal support on each side of the door to bend the wicker against making the doorway stable. 3. Bend the horiz. wicker pieces against the vertical metal supports & secure w/cord threaded in a needle w/a large eye. :)
