I only have a bachelors degree in psychology so i'd be guessing...
however, i'd say it was "healthy" so long as it wasn't ONLY animated women in which you fantasize about... and so long as the animated women you fantasize about are within the social norms in age both physically and mentally.
The first being because if you fantasize only about animated women... it's going to be a LOT harder to form a meaningful relationship with a real woman and the second due to well, other things that has littlle to do with the animation itself and more to do with things like pedophilia.
Afterall... we didn't always have photographs you know... which meant the earliest forms of porn had to be drawn or painted or whatever in the first place.
