It is easiest for me to block off a corner with grids for my piggies for floor time. I have pig who for some unknown reason loves chewing on the metal grids (just in floor time not in her cage, unless she knows carrots are coming). When she chews on the grids she tends to knock them over. Does anyone have any ideas on how to connect the girds to the wall (minimizing holes) or anchor them so that she can't pick them up and knock them over?
