Opossums are the only marsupials that live in North America. Like other marsupials, their young develop in an exterior pouch like kangaroos rather than inside a womb within a placenta.
They’re omnivores that will feed on almost anything. But because they have so successfully adapted to human environments, they can easily become nuisance animals in urban settings or even in neighborhoods where they forage through trash cans.
Despite their adaptability, opossums are slow runners with poor eyesight, which is why they are easily run over by cars. When they are alive, however, they can disturb pets and create a racket outside while going through garbage. They can become a pest issue on your porch or inside your basement, attic or crawl spaces.
