This randomly popped into my head today and I figured I'd go back and watch this. What a weird animation. The animation quality is mediocre and the way the images are pasted in is really awkward, but I think that's kind of the point. The low budget animation is sometimes quite charming (though sometimes not.)
If there's anything that needs work here, it's the sound. The lack of background music and stiffness of the voice acting (pauses between lines are definitely too long) makes the animation feel slow and clunky, although the swearing ends up being pretty funny due to how unexpected it is. The diabeetus cat also has some background noise in his voice clips that should be edited out.
