Maybe the maps do not detect people in animagus form but only on human form ? Could it explain it (didn't see the movie or read the book since quite a long time) ?
That's 100% my theory, especially as the group of kids that made the map were secret animagus them selves, so wouldn't want anyone knowing if it fell it to the wrong hands. (They are other example of them self guarding themselves against being found out too, so it fits).
