I have caught 2 of these under my house while trying to get rid of the standard field mice that come in during Fall. They are about 2x the size of mice. No nipples showing. Soft fur. Big rear legs. See photo. Is it a juvenale "roof rat"?
Lane County Oregon rodents
Looks like a roof rat. Roof rats are adept climbers and not surprisingly are apt to build their nests in locations above ground. However, they may sometimes also build nests in burrows. These rats are primarily active at night. Scientists have noted that the roof rat’s long tail is adapted to enhance their ability to climb and functions to assists them in balancing. They do not like water and are rarely in sewer systems. Roof rats are omnivores and will feed on many types of vegetation such as fruits, grains, seeds and grocery produce. Also, roof rats are likely to consume insects. Just like Norway rats, roof rats destroy far more foodstuffs by contamination from feces and urine than from consumption.
Thanks for the prompt response.
You are welcome. Good luck in the control.
