The phenomenon of DIY cat ladders comes in all different sizes and designs, and for some reason, Switzerland seems to be particularly prone to it.

They represent sociological, architectural, and artistic qualities that are further developed in the accompanying writings, ranging from a straightforward wooden plank to intricate, scaffold-like constructs rising up to four stories in a zigzag pattern. As a result, the book can be used as a reference as well as a source of ideas when building your own cat ladders.
