It was great!
Animated cats serving as musicians? (now where did that come from...?) The flash itself was pretty good; now I haven't seen the original Cat music video, but I bet it's reminiscent to this one. Judging from the colorful and vivacious pre-loader to the kick-ass animations and music, this entry proves to be inferior in the MV genre.
Keep up the great work.
PS: It was pretty funny, as well, seeing the fuzzy felines rocking it out.
