8” x 1” 3’ or longer , L brackets (Ijamsville 21754)

Looking for scrap lumber to build a cat walk around the ceiling perimeter of my daughters den for her new kitten and two cats . Looking for shelf L brackets , anything I can spray paint and clean up is fine . Shelves from book cases would also be great ! I can build steps from them. Sisal rope would be a great help! I can pick up within ten miles of 21754 . Thank you
