These battles escalate and spiral up through species, I believe. Just like if the ants, bees, wasps, birds, fish do brood parasite slavery humanity isn't far from open slavery instead of covert. The Lyra draco wars are from taking a stand and enforcement of boundaries with feral cats and WW2 might have been part of that. My theory.
