Possums are tiny creatures which are often mistaken for big rats. They are nocturnal animals that are found throughout the North America. Though they don’t attack humans physically, their presence is still not liked by the homeowners especially because of the haunting noises they make. Possums can eat pretty much anything and you can often notice them around the trash cans and inside the yard. Though opossums are not aggressive animals, they can create weird sound to scare away the attackers.
