possums don't carry rabies, never do squirrels or chipmunks. I knwo this because my son got bite by a chipmunk and i called animal control, the doctor and the emerceny room at the hospital, my poor son, I did more to him than the chipmunk could do, scrubbed his bite with soap and then poured alcohol on him, i think screamed more on that than the bite. Just check him over good for any bite wounds and make sure you clean them good, but not the way i did my son.
