DIY Grid Panel Catio
Use wire grid panels to make an outdoor cage for your cats! Gather as many grid panels and connectors as needed. Assemble the panels with a connector on each corner to make a tall cage that has alternating levels inside for your cat to use as steps outside a window. Get a rubber mat, cut it into squares the same size as the grid panels, and attach a piece of the mat on each level with zip ties. Assemble more grid panels to create a tunnel, then assemble the panels to make a large area for your cats to play. Attach a net over the top of the large area to enclose it and cut out a hole from the window screen for your cats to enter the cage.
