A great manga, or Japanese comic book, by Makoto Kobayashi, about an orange tabby cat. Each book has several short stories about the cat. It's funnier than it sounds -- intelligent, witty, observant of human and cat psychology, and well drawn -- it's no Garfield.
My favorite story was one showing Michael washing himself; he accidentally leaves his tongue sticking out of his mouth. This sometimes happens to cats and they walk around for a long time looking idiotic. Anyway, as Michael is going about his business outside, various animals and people -- including a policeman -- yell "Hey! Your tongue's out!", chasing him down the street... Finally some other cats, whose language he can understand, tell him to shape up.
