As this is a collection of short stories, it would fall under our Books/Novels rule, which does not require individual pages of the work to be customized to a high degree.
By the way, we wanted to note that the name of the pdf has a (2) in the file, so it's "Life's a Zoo (2).pdf" rather than "Life's a Zoo.pdf", which seems unintentional just in case you wanted to fix that!
