DIY Skyscraper Scratching Post

Construct a cardboard skyscraper to be a scratching post for your cat! Drill a hole through the center of a wood board and drill a hole into a wood dowel. Attach the wood dowel to the board with a screw. Draw a template for each layer of the cardboard, cut out the templates and use the templates to cut pieces of cardboard into the shapes needed. Assemble the pieces of cardboard on the wood dowel.
