The dusky-footed woodrat is a medium-sized rat-like form with large, nearly naked ears, protruding eyes, and a long tail. The dorsal pelage consists of hairs with steel gray bases, a band of ocherous buff, and a tip of black. Hairs on the throat and belly are white. Although variably in extent, a dusky splotch occurs on the dorsal surface of the white feet.
In Oregon, this woodrat occurs from the California border northward along the coast to near Bandon, northward inland through the Willamette Valley and other interior valleys to near Mollala and Monmouth, and northward to Brownsboro, Jackson County, the Sprague River and Lake Albert south of the Cascade Range.
The dusky-footed woodrat constructs houses of sticks and other debris in trees or on the ground. Commonly, adjacent stick houses are connected by paths between ground level openings that lead to large central chambers through a maze of passageways. A central chamber is used for food storage; and some houses have a latrine. This woodrat is more active at night, but may be abroad during daylight hours.
