I recently got a dumbo rat from a rescue. She is little, under a year old. I noticed white dots at the ends of her fur and something on her ear. I am really irritated because I drove an hour out to pick her up, and paid 3x what I normally would have if I had gotten her from a petco, but I think the poor baby is sick and must have mites or lice or something. Could anyone help me figure this out? She is being quarantined from my other 3 and doesn't seem scared but doesn't like being touched.
