You will have to check your state, they are illegal as pets in many states, google the National Flying Squirrel Association for messageboards and info. Try looking into Sugar Gliders.
You probably can not find them at big name pet stores, you would have to try some small town shops or local pet stores. They might be able to order them or have them.
Pet stores do not sell flying squirrels. They are not considered domestic or exotic animals and live in the outdoors in their natural habitat. Squirrels are in the roden family.
