The cat cave.

Is it possible to combine a cat's lifestyle with human use to reach the size of a cat? The study of non-equilateral polygons produced the basic structure of this situation: a reproducible unit that forms a cat community after rotation/stacking. It not only provides a cavernous shelter for stray cats to eat and away from wind and rain, but also creates an undisturbed place for them to entertain, satisfying the onset of common behaviors such as hiding, digging holes, climbing, running, and jumping.
