Wikipedia Abstract

The Virginia opossum (Didelphis virginiana), commonly known as the North American opossum, is the only marsupial found in North America north of Mexico. In the United States, it is typically referred to simply as a possum. It is a solitary and nocturnal animal about the size of a domestic cat. It is a successful opportunist. It is familiar to many North Americans as it is often seen near towns, rummaging through garbage cans, or as roadkill.
