DIY Milk Crate Cat Condo

Use milk crates to create a condominium for cats on a wall! Gather plastic milk crates. Cut holes in the side of some crates, or in both sides of other crates to make a tunnel, and sand the cut edges of the plastic smooth. Determine the ideal location for each crate and bolt the back edge of each crate to the wall. Cut squares of carpet and use Velcro fasteners to attach the carpet pieces to the tops and insides of the condos. Attach pieces of non-slip deck planks to the wall like shelves at the ideal locations for your cats to access the various condos. Use a paw print stamp to paint paw prints along the walls for added decoration and tuck small blankets into several of the condos.
