DIY Cube and Coroplast Cage
Assemble a C&C cage for your guinea pig! Use the grid connectors to assemble the outside walls of the cage. Cut a piece of Coroplast to the size needed, mark the edges of the cage walls on the Coroplast and use a box cutter to score the Coroplast along the lines for the flaps. Cut the flap lines, fold each edge of the Coroplast up and wrap the flaps around each wall. Use tape to secure the flaps in place and set the Coroplast box inside the grid walls.
