I have a Southern flying squirrel that is scratching her fur off. The vet said it was either fleas or mites and told me to put Advantage for kittens on her. I did that Saturday and she is still scratching. The day before she started this I got into some poison oak. I am her main care giver-could she have gotten this from me and what do I do? She is about 7 weeks old just in cause you need to know.
