I really liked the movie and agree with all that you have said, but to be honest I can't believe that nobody has said anything to Mittens story and it isn't even mentioned at the top. I think it is very sad because this happens to many animals, not only to cats or dogs. If kids want an puppy, a kitten or anything like that for christmas, you must be willing to care for it too, cause usually after christmas when the animals have grown, children don't want them anymore cause they have grown and they are too much work. I'm not saying that every child acts like that but many do..
That's why I was surprised cause these things MAKE ME SO ANGRY!! .. Sorry :D
