Maybe because there is something inherently absurd about Warrior Cats as a series? It is Game of Thrones with feral cats for third graders and it has been going on for twenty years. I just looked up the series on Wikipedia and this is an actual quote: "Major themes in the series include adventure, forbidden love, the concept of nature vs. nurture, acceptance, the struggle of good vs. evil, the reactions of different faiths meeting each other, and all people being a mix of good and bad. The authors draw inspiration from several natural locations, and other authors such as J. R. R. Tolkien, J. K. Rowling, and William Shakespeare." IT IS ABOUT FERAL CATS.

I was o b s e s s e d with these books as a kid (although, again, looking on Wikipedia, it turns out I only ever read the first three sub-series; they're currently on #8) and I'm sure they're, like, objectively not actually good books, but they were such a fun world to play around in and the Official Warrior Cats Fan Forum was actually my first foray into fandom, circa like, 5th grade. (Mostly in the form of roleplaying as Warrior Cats OC[s] on the internet.)
