An animal with human-like characteristics. A human with animal-like characteristics can also be called an anthro, but technically they are not.
An anthro is, technically, an animal that can: a) walk upright, b) talk, or talk somewhat (AKA has human vocal chords), c) has human features (i.e. a
centaur, half human, half horse), d) has
the bone structure of a human, with some of its animal counterpart (i.e. a cat-anthro that although looks like a human, can jump like a cat). These characteristics separate anthros from humans with
cat ears and tail (or something like that).
