Grouping the characters in Pax

           So far we read up to chapter six in the the book Pax by Sara Pennypacker. In the very beginning peter (a boy) let Pax (a fox) out into the wild, and Peter went to live with his grandpa and is his dad going into the army. Pax who is  in the wood met two other foxes named bristle and runt. If I had to group them I would group them in foxes and humans. For foxes I would say Pax, Bristle, and Runt and for the humans I would say Peter, the dad, and the grandfather. Also it is the same thing If you group them in the characters introduced in the peter chapters and in the Pax chapters.
