The fact that hunting, killing, and eating other sentient beings is routine in this world is regarded as ordinary and acceptable. Starting in 2010, Kell herself runs a company dedicated to doing this as efficiently and widely as possible. On its face, this should be a horror worse than the Holocaust. The strip plays all of this for light comedy.
Not to mention that it's perfectly acceptable for a CEO to be eaten alive by anyone who wants to succeed the position. And it is in fact the normal way of doing things, to the extent that letting a defeated foe live is unheard of. Furthermore, older strips joke about workers being "fired" actually being killed and Kell is unusual for getting let go without being devoured.
With the inclusion of athletics and especially the Olympics in recent comics, the continued references to predation seem to imply that the losers of an event could end up eaten. Very jarring when applied to how human athletes are treated, especially in one instance where it looks like they actually off the winners. That just gets confusing.
