Norway rats tend to be 'chubbier' and have shorter snouts and tails. Roof rats are sleeker and have much longer tails.

Norway, Roof, Pack & Bushy tailed-wood rat.
There are two basic types of rats. Black/roof rats and Norway/brown rats. The brown rat, is also known as the Norway rat, house rat, gray rat, barn rat, and wharf rat, is one of the best-known and is the larger of the two. Roof rats are also called black rats and ship rats.
The two main types of rats that cause problems are the Roof rat (Rattus rattus) and the Norway rat (Rattus norvegicus), also called the sewer, wharf, or brown rat.
A roof rat can live up to 1,5 year.

NO, it's just a rat <><><> All rats are mammals.
Norway rats (Rattus norvegicus), sometimes called brown or sewer rats, are stocky burrowing rodents that are larger than roof rats. Their burrows are found along building foundations, beneath rubbish or woodpiles, and in moist areas in and around gardens and fields. Nests may be lined with shredded paper, cloth, or other fibrous material. When Norway rats invade buildings, they usually remain in the basement or ground floor. The Norway rat occurs throughout the 48 contiguous United States. Generally it is founds at lower elevations but may occur wherever people live. Roof rats (Rattus rattus), sometimes called black rats, are slightly smaller than Norway rats. Unlike Norway rats, their tails are longer than their heads and bodies combined. Roof rats are very agile climbers and usually live and nest above ground in shrubs, trees, and dense vegetation such as ivy. In buildings, they are most often found in enclosed or elevated spaces in attics, walls, false ceilings, and cabinets. The roof rat has a more limited geographical range than the Norway rat, preferring ocean-influenced, warmer climates. In areas where the roof rat occurs, the Norway rat may also be present. Their favorite habitats are attics, trees, and overgrown shrubbery or vines. Residential or industrial areas with mature landscaping provide good habitat, as does riparian vegetation of riverbanks and streams. Roof rats prefer to nest in locations off the ground and rarely dig burrows for living quarters if off-the-ground sites exist For more information about rats, please check out my Bio page.

The dust over them or absence thereof will tell you if they are in a secluded area. Look for tracks in the dust. You can use an inert tracking powder if there is not already dust there for you to use.
Rats are carnivores. They eat meat.
