I picked this girl up today and she seems to have a bit of a skin condition that I am just not sure about. I don't know if it is something as minor as dander or dandruff or an actual fungal thing. She is alert, eating and active. Her vent is clean. Their are no lesions or sores on the white crust. The white crust is only on her face. She does appear to have a minor case of lice. Any ideas? Thank you!
