    The roof rat, Rattus rattus, is a problem species in Sonoma and Marin County. This rat is slender and agile, and the tail is longer than the head and body. Roof rats will enter buildings if given the opportunity, and often use utility lines and fences as runways. Roof rats prefer to feed on fruits, nuts, ivy, and pet food commonly found in residential areas.

    The Norway rat, Rattus norvegicus, is a common species in Sonoma and Marin Counties. It is generally found in agricultural areas, creeks, sewers, and developed neighborhoods. The Norway rat is larger and more aggressive than the roof rat. Its eyes and ears are smaller than the roof rat's and the tail is shorter than the combined head and body length. This species usually lives in underground burrows, and feeds on garbage, pet food, cereal grains and vegetables.
