Is there no one who will take her to the vet?
Many times these abscesses require debridement and surgery, they don't usually get better on their own.
The bacteria from abscessed wounds can cause more problems than a few, this cat really needs someone to intervene and take her in for medical care.
And there is really no way of knowing what organisms are invading the wound without doing a culture. Educated guess yes, but certainty most likely not.
