Wow, she’s very light colored. She doesn’t look like any eastern gray I’ve ever seen. Adorable.
As for the spots. Ringworm can be treated with an over the counter ointment for athletes foot or yeast infections. It is persistent and you must be consistent putting the medicine on. In between applications cleanse the area with a diluted betadine solution adding a little water so it looks like strong tea. There’s no need to rinse in between, but allow to completely dry before applying the anti fungal medication.
The spot in this photo doesn’t look red at all. Squirrels have been known to rub the hair off of parts of their nose, neck or head when they go in and out of a nest box or some other hard surface. Or stick their noses through cage bars.
