This is interesting, but I'm sort of not at ease over whether or not this is truly pixel art. Traditionally, pixel is the creation of an image pixel by pixel by pixel. While I can see some pixel art elements used here, the majority, I would say, isn't quite so. (Obviously there's a large brush used here and another there.)
While it is interesting work, I think you should edit it into another cat.
aaah dont save your images as jpgs!! mspaint isnt always
fuzzy, its just when you save images as .jpg they smear
together. gifs can animate, but they loose your colors, try
.png or .bmp !! other than that, its beautiful, it looks like
something made in photoshop
