From the CDC website:
Small rodents and other wild animalsSmall rodents like squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, and mice) and lagomorphs including rabbits and hares are almost never found to be infected with rabies and have not been known to transmit rabies to humans.
From 1990 through 1996, in areas of the country where raccoon rabies was enzootic, woodchucks (groundhogs) accounted for 93% of the 371 cases of rabies among rodents reported to CDC.
In all cases involving rodents, the state or local health department should be consulted before a decision is made to initiate postexposure prophylaxis.
