Interesting about the rats not chewing metal. Their teeth are approx 5.5 on the mons hardness scale so Lead and Aluminium are within their range. It does seem that steel would not be possible.
My bad for passing on an urban myth. Probably still stick with glass in the cement though, it's easy to mix in a bucket.
