Update. We have isolated her in the garage. We brought her in and washed her vent area. We didn't notice any redness or irritation. We soaked her in warm epsom salts water for about 5-10 minutes. Took her out and dried her as gently as possible. Treated the vent area with an anti-fungal cream monistat. Her vent seems to be poked out like there was an egg in there. Does this sound like a typical treatment for vent sleet? Thanks!
