I don't think that Grimm do digest anything they eat. It is quite possible that their bodies just dissolve anything they consume. Given that the WoR on the subject says that they apparently don't need to eat suggests that they might not metabolise anything but instead absorb energy from their environment by some kind of absorbtion and convertion of stuff like sunlight, heat and even vibrations.
