Raccoons

Raccoons are nocturnal mammals, and are found in all over North America.
Raccoons don't hibernate, but they do stay inside most of the winter to keep warm. Raccoons live in trees, brush piles, or caves. often, raccoons share nests, and there can sometimes be over twenty raccoons in one nest!

In February and early March raccoons will have a litter of about 4 kits. Kits are born helpless, and are considered adults at the age of 13 months. A raccoon in the wild has an average lifespan of five years.

Raccoons are omnivores, which means they eat both plants and animals. Nuts, berries, small animals, and seeds are eaten, but raccoons also go for carrion (dead meat) and garbage.
Wild raccoons can have rabies, so always be careful when around them.

I don't have a picture of a raccoon, but you can see some here.
