I've reread this 5 times now and I'm still baffled. When we sell them, we tell people what they eat. The videos that talk about them.... talk about what they eat. How did your friend manage to get one without hearing at least once that they eat little furry mammals? Made me laugh, glad she's with you now!
Sounds like you have the mite thing handled, and that you caught it early enough for it not to really come a serious issue.Best of luck
