As one reviewer put it, the cats in the series are "true to their feline nature", leading some critics to jokingly comment that the books will "leave readers eyeing Puss a bit nervously", and wondering "what dreams of grandeur may haunt the family cat". However, this realism also means that the series contains a relatively large amount of violence, with one critic stating that it is "not for the faint of heart". Several critics have compared "Warriors" to Brian Jacques' "Redwall" series, though one commented that it was "not as elegantly written". "The New York Times" called the series a "hit with young readers", specifically because of its "sprawling universe", and the series appeared on the "New York Times" Bestseller List for a total of 117 weeks, as of 24 November 2013.
