What qualities define an ideal, long-term cavity utilized by a woodrat for residence?

Answer

A deep, dark cavity that offers defensibility and multiple escape routes.

When seeking a permanent residence, woodrats prioritize security and protection above all else. The most sought-after natural or artificial shelters are those described as deep and dark cavities. Crucially, these ideal homes must offer a high degree of defensibility against potential predators, which is achieved by having multiple, redundant escape routes. Dryness is also a non-negotiable requirement for long-term habitation and midden preservation.
