Viking kittens forever!
This is one of your better ones, if only because it's awesome how it has so many cats in it! My only complaint is that it exists in an infinite loop. Of course, other stuff I have favorited is like that, so I guess it must have been something else. What's nice about this is that the dialogue is more understandable. You get more of a sense that these kittens are out to do something. I love how they are superimposed on the lake background.
As with the Spongmonkey's one, it's great to see how the cut out animations work. It reminds me of "South Park", which has been perfect with that. Every single photographed image just seems to have its own personality and jumping out at you. I am so glad you went on to become so popular. I'm going to recommend this for the "Cats" series right now!
