Hmmm, maybe we can market this as a diagnostic tool; release a dozen or so mice/rats into someone's house, and assume the cables they chew through first are overloaded circuits. Bill accordingly, subcontract extermination.
You could get your own taskforce of rodent exterminators.
However, frequent replacement of the diagnostics equipment could eat into your bottom line.
Hmmm, mice and cats in the same work vehicle may not work out that well.
