This nice piece is by Didier Convard, from his series Chats (“cats”).
From what I can tell, cats are the dominant species in this reality, with humans amusingly playing more of a primitive, underclass role.
More on Convard at Lambiek (note: he’s not to be confused with Didier Conrad), and more samples from Chats here.
If you can read French, I’d check the same sites that college students use to download textbooks. Archive.Org is also preserving some BD content, I believe.
I don’t really feel comfortable saying anything more, so please follow up as you see fit. Thanks.
