Look at it again. The "bad" guys aren't cats, nor are they Asian.. they're camels and are wearing arab garb. I didn't catch this at first either! I just assumed it was the same manga, rather than a more "contemporary" version with the same rabbit characters.

Still.. being not a fan of anime/manga whatever, I can't wait to see this. The contrast of cute, bunny-suit characters set in a war condition looks to be a beer n' pretzel to movie.
