24:4 Warriors: into the wild; by Erik Hunter

It's a very easy read, pretty cute. But it is a little on the violent side. It is a fun read, though. It's about a cat named rusty, who was a humans pet, then escapes, and goes into the forest, where he is attacked by a warrior apprentice named Graypaw. He fights well for a "kittypet" as the warriors refer to him as. however, they learn to respect him better later on. You have to learn the rest on your own.
