Species: chipmunk taur
Anthro above the waist, quadruped feral below, rodent taurs are characters built along similar lines as the classic centaurs of Greek myth, only using anthro rodent bodies above the waist in place of the human component and/or feral rodent bodies below the feral's neck in place of the horse body. Of course, since chipmunks are also a type of ground squirrel, this tag will imply ground squirrel taur.
