I have seen all sorts of wiring methods in these areas (inspecting old work) and I would highly recommend against using NM or NMC/UF type cables. The cloth type seem to hold up, but way to often I have come across rodent damaged conductors with the plastic styles. I will try to remember a camera for next time.
Of interest, I have not found rodent damged conductors inside heated buildings yet, though I have found many conductor damged rodents there.
