They come in all shapes and sizes, and somehow the phenomenon is especially prevalent in Switzerland: homemade cat ladders. Taking the city of Berne as an example, photographer Brigitte Schuster shows the variety of ways humans facilitate the comings and goings of their feline friends in the context of the surrounding architecture. From a simple wooden plank to complex, scaffold-like constructions rising up to four storeys in a zigzag fashion, they express sociological, architectural, and aesthetic peculiarities, which are further developed in accompanying texts. As such, the book serves as both a guideline and source of inspiration in creating your own cat ladders.
