Virginia opossum tracks are unusual: their front feet are wider than they are long. They are also unique because the 'thumb' on the back feet is separated from the rest of the toes. They have claws, but their claws don't always show up on their tracks. When possums walk they bring their back left back foot up to their left front foot and then their right back foot up to their right front foot. So, when you see their tracks, there will be several groupings of a single front foot and back foot together.
