It's a new generation of rodents - millennial rodents if you will. They prefer avocado toast, but soy wiring will do the trick in a pinch.I just want to point out that rodents have been chewing wires ever since they invented wires. In my opinion there is no reason to believe that rodents have turned into “chai latte with soy milk” sippers. I have seen rodents chew rubber, plastic and paper based insulation as well as numerous other things and I have a hard time seeing how soy based insulation is more attractive. Just my sceptical outlook.
