Why is it Garfield, Arlene, Nermal, and Squeak's mouths now move with their dialogue on this show? The animals didn't actually talk in the comic strip or Garfield and Friends, and yet here they appear to actually be talking, despite Garfield saying in some episodes he actually doesn't talk.
This could just be for the sake of the audience. Besides while they may not be speaking in human terms, they may be speaking in animal ones. (i.e. meowing, barking etc.) A similar trick was done in the remake of the Doctor Dolittle Film.
