This monograph on the biology of animal building embraces all groups, from simple invertebrates to primate toolmakers. It looks at the behavioral and anatomical equipment animals have in order to build, as well as the materials available to them. It examines how architects are able, singly or collectively, to produce complex structures often much larger than themselves. It also looks at the costs of building, the properties of completed structures, the ecological impact of them ,and their effects on the evolution of animal builders.

The Cat in the Hat introduces beginning readers to maps–the different kinds (city, state, world, topographic, temperature, terrain, etc.); their formats (flat, globe, atlas, puzzle); the tools we use to read them (symbols, scales, grids, compasses); and funny facts about the places they show us (“Michigan looks like a scarf and a mitten! Louisiana looks like a chair you can sit in!”).
