Her vent looks a liitle swollen, but not prolapsed at this time. Could she have been attacked by a predator? She has that large scab and bruising, so hard to tell what exactly happened. It doesn't look like there is any vent damage so that is great. Her wounds probably would benefit from a warm soak once a day, followed by applying a plain antibiotic ointment.
Sorry - maybe I should have included your post.
Would it be ok to apply neosporin to her?
