I don't know about this....I mean think of it in their perspective....to them making skyscrapers ain't that big of a feat....just like beaver dams, ant hills, termite mounds are not that big of a deal to us....and ain't the definition of cannibalism means to eat your own kind?....so it's not cannibalism....aliens treat humans as food and as a pet....pretty much as how dogs are treated in some other countries.....
I mean the sort of "cannibalism" as eating another sentient being who is in your league - or close to - of understanding. It's like a lion who's eating a cat (I don't think that happens regularly though). Or humans eating dogs, just as you mentioned. I don't know if the aliens are more clever than humans or/and just plain cruel to other species, not only towards humans (I wonder if there's any PETA-like organization amongst the aliens, that would be fun :D). But gruesome parody of us, that's for sure, this manga one day will make me a vegetarian :)
