I go by the Disney definition. If it wears clothing, it is a person. If it does not, it is an animal. I would add language and tool use. Pluto once used a record player by using his tail as the needle, I don't think that counts though.
In Dungeons and Dragons your creatures would be called monstrous humanoids. Even animals risen to human intelligence but retaining animal form were reclassified as magical beasts. The point being that however much hair you have, however long and sharp your nails and teeth are, however beastly seaming something is, people act one way and animals another. Beings that talk, wear clothing, use tools, and above all else, reason, ARE NOT and CAN NOT be animals.
