I recently came across this guy who catalogues and records ancient and esoteric mousetraps, and immediately thought how interesting it would be to see some of these scaled up and used on anthro mice or rats.
Mostly Im just leaving this here as inspiration.

If, however, I were to make any suggestions, I have to say it would be ridiculously cool to see a party of mouse adventurers, A-la Redwall, go through a dungeon stocked with such traps.
