Anthropomorphism Scores

I made a scoring system to apply to works of fiction
With animals in prominence, describing their depiction.
A zero means they act the same as critters in RL.
A one means they converse, but human characters can’t tell.
A two means they speak human tongues but occupy the same
Old roles as livestock, zoo exhibits, pets, or hunting game.
A three means they’re the humans’ peers, if humans should exist,
But still perform some animal behaviors with a twist.
And finally, a four means they’re behaving just like us.
(So why not make them human? There’s a topic to discuss.)
A lot of works would get a score that’s somewhere in between.
In Downscale, for example, hardly anyone has seen
The talking snake, so I would think to rate it 1.5.
I hope you like my system, tho I doubt that it’ll thrive.
