Saw it already long ago
it's very cute ain't it? and no, the music is not japenese, even though it seems pretty jap. MAYBE it is japenese, but if it is, the song itself sounds a lot more like chinese or tai or maybe some other asiatic language. I should know, been listening to japenese music for about 13 years thanks to anime, and jrock/jpop groups, and also chinese songs thanks to my parents..
Now back to the flash...poor cat, but he likes it in the end...
That's all I can say, poor cat, heh. Watch it, it's good stuff
