Each page is dedicated to a different animal, with one of Jenkins’ cool collage illustrations and a few simply lines of text describing how that animal sleeps, on a clean white background that makes both art and info pop.  Sleeping is something we all do, and something we have in common with all living creatures, but how some of these animals sleep range from the mildly interesting to the fascinating.  More information about each animal is offered in the back of the book for readers who want to know more.
