@foone The house I grew up in had knob-and-tube wiring and those wires were fiber-wrapped and "nothing bad happened". That said, that house also had a two-story outhouse (fortunately offset slightly.)
Vehicles moved from fiber-wrapped wiring to newer plastic-coated wiring is actually much tastier to rodents. Plus, my old #SeriesLandRover with all that fiber-wrapped wiring only had one fuse, so super easy to work on.
I digress. Yes, hemp cat6 with rope oil and porcelain connectors.
