Ringworm treatment in cats most effectively combines topical lime sulfur dips with oral antifungal medication, with evidence-based protocols achieving cure within 4-8 weeks when consistently applied.
Ringworm treatment is a welfare commitment requiring consistent owner application - cats that receive irregular treatment take longer to cure and experience prolonged skin discomfort. The lime sulfur dip, while olfactorily unpleasant, is the most effective topical treatment and causes no pain when properly diluted. Foster families who commit to the twice-weekly dip schedule and daily oral antifungal achieve the fastest cure with the shortest welfare cost. The goal is two consecutive negative cultures that confirm cure and enable adoption - consistent treatment is the most direct path to that welfare outcome.
