I went to this movie with no expectations of any kind, except that it was Japanese and animated. What I saw was perplexing and at times disturbing, but completely engaging from beginning to end.
If you consider satire comic exaggeration with a moral punch, then this might be satire, though it's difficult to figure out what the moral is. The connections between the title character, Catty & Co., the Fritz Lang style 3-D artificial world, and Minerva are spotty. It would probably help to take notes during the rotting old professor cat's lecture, both at his slide show presentation, and during his confrontation with Michelangelo. For those who haven't seen it or read it elsewhere, these are all cartoon cats.
But this is a movie, and you shouldn't need to take notes to enjoy it, and I enjoyed it thoroughly as it was presented. I love the black and white, sharply detailed designs, the splashes of vivid color, especially that painting Tamala discovers in the basement of the museum. The violence gets pretty intense in places, but it works very well and doesn't seem gratuitous.
Tamala is worth a second look, but seems to be strictly short-run in most venues here in the U.S. DVDs are available from their website, but they're Region 2. It will probably be a long while before I see it again, but I anxiously await that chance.
