Raccoon pelts are salt and pepper colored. They are playful, curious and excellent swimmers. They feed mostly along streams, lakes and ponds, but will wander from water. Their dens are in hollow trees, logs, rock crevices or ground burrows. In cold weather, raccoons may sleep for several days, but do not hibernate. Chiefly nocturnal, raccoons are especially active during the autumn. They are solitary creatures except when breeding and caring for their young. Their diet varies; fruits, nuts, grains, insects, frogs, fish, birds' eggs. Washing their food enhances a raccoons sense of touch in its toes helping them discern non-edible matter. They mate between February and March, bearing two to seven young in April or May. In fall, young raccoons may wander up to 160 miles, but mostly less than 30 miles. The raccoons chief enemies are dogs, hunters, and cars.
