Probably worth noting: As of chapter 9 (though there were some hints of it before then) this is genuinely dark. Plots, murder, psychological horror peppered throughout the surrealism, that sort of thing.
Doesn't mean the series isn't about a cute eldritch horror cat. But it's not fluff reading. Might need "horror", "drama", and/or "psychological" tags if it stays this current course (can't say it's clear as of yet where the main direction of the story is heading for sure yet, though).
