Eyes open in 58-72 days. Weaned at 13-15 weeks. Body temperature is 90-99 degrees. They are scavengers and help keep the earth clean. They later carry their juvenile opossums on their backs wherever they go.
Opossums are the only marsupials in North America.
Always check a dead opossum for babies. But they will be if you don't check. If there are babies in the pouch, try to pull the babies off the mother, if you can't, transport the mother and babies to the nearest rehabilitator. If baby opossums are at least 10-12 inches long, they are able to be on their own unless you see that they are sick or injured. Treat an opossum like a raccoon when it comes to one being a pest.
