Our family has lots of non-fiction books on animals, nature, and science in the house. A reference book is a great thing to have around because you never know when school-age children will need something in it. Granted there is that whole internet thing, but a book allows for that random sense of discovery that online searching simply doesn’t satisfy. However, odds are that all of, or almost all of your non-fiction animal reference books are encyclopedic, or listing in the presentation. That certainly leads to discover and learn about new creatures, but might not motivate kids to read it page to page. What Breathes Through Its Butt? is a non-fiction book on animals, but it’s unlike any critter book you or your kids have seen.
