For a purely Redwall game I was thinking that Anthropomorphic creature would probably take the place of humanoid with its own list of subtypes.

For a regular game with these brought in as an option, Anthropomorphic creature might be a subtype of humanoid. Or they could be divided up into a list of subtypes for humanoid such as anthropomorphic mouse.

Looking back now I suppose it would not hurt to drop Keen Senses off of them to bring the average RP down a bit.
