Redditor Collinferal used geektastic carpentry skills and $140 in materials to create this awesome Super Mario Bros.-themed, wall-mounted cat climber for a friend’s lucky cat.
"It’s got climbing-friendly sissan twine-lined pipes. It’s got scratch-friendly carpeting. It’s got a door, in case you want to make sure your cat is still alive inside it. Best of all, you can mount it high on a wall so the cat has to jump on something else to reach it, and then you can take that something else away."
