If you’re really serious about this, you’ll need to design a scientific test that others can repeat and verify your results.
Here’s some thoughts:
Get some pet store rats and cages. One caged rat is the control, supply it with plenty of food and keep it happy. Give it a block of wood to chew, some soy wire and some traditional plastic wire. See what it prefers.
Set up another caged rat but don’t feed it quite as much to see if hunger makes it go for the wires.
You may need to repeat this with several rats to get a big enough sample size to analyze.
Or you could just throw a bunch of wire around a dumpster and see what happens.
Good luck, let us know the results.
