QUESTION: She has draining coming from the ear with foul odor. Indicative of an infection ? If so, is it easily treated by the local vet with antibiotic ?

Answer
This is most likely a middle or an inner ear infection.  Many vets can treat this type of infection, but I would try and get this cat to a vet with a video otoscope (you may have to make some phone calls to see if anyone has one in your area) so that if there is a growth (polyp or tumor) or a middle ear problem, they can see it.
