Attacking of hierarchy itself means monkeywrenching the innate and apparently biological tendency toward dominance-and-submission behavior. This I assume is why the cat is an anarchist symbol. Certainly the cat is a less hierarchical species than the dog, but they are very territorial. I don't know if it's true, but I heard on one of those wildlife shows on teevee that parrots (at least some species) are truly non-hierarchical, and don't exhibit any kind of alpha-male or alpha-female behaviors. I'm skeptical but cautiously optimistic. Laure Akai use to refer to the Revolutionary Communist Party as the Remote Controlled Parrots.
