Any alternatives to BISAC subject categories in iTunes Producer

Thanks for responding. My novel, KIP, is about a fox living in an undeveloped area of a university campus whose habitat is destroyed to make way for a new basketball arena. Appropriate subject headings would be something like "animal stories" or "survival stories" or even, more specifically, "fox stories." But I didn't see anything close to those among the BISAC headings. I went with "Action and Adventure" but that doesn't quite hit the mark. I know there's a way to specify age group and one might think my novel would be appropriate for younger readers but actually the style in which my novel is written would be too challenging for most readers 13 and under, so the age level is listed as 13 and up. The description I included pretty accurately describes the novel but I'm not sure if someone searching in the iBooks store would pull it up via keywords in that description.

Thanks, they do sound OK--except my book is fiction and none of the fiction categories really work. In iTunes Producer if you designate your book as fiction, you must choose a subcategory from among those listed. I could not figure out a way to add the NATURE categories you suggested while retaining the fiction designation, which is essential. But I will look into this and see if there's a way to do it.

Thing is, if you go to the iBooks store and search the term ANIMAL STORIES you get several screens of titles. You also get many titles when you search SURVIVAL STORIES or FOX STORIES. But my book KIP

is not among them. So the iBooks store does recognize those terms; they're just not available in iTunes Producer. Perhaps books that get into the iBooks store through some other means than iTunes Producer have more options for descriptive search terms.
