When assessing house mouse (*Mus musculus*) nesting habits, how do they differ from the excavation behavior of the Norway rat?

House mice seek out small, concealed areas *within* existing structures rather than excavating major burrows

Unlike the Norway rat which excavates burrows, the house mouse successfully colonizes small, dark, concealed spaces inside structures, such as behind drawers or deep within wall cavities.
