While it can suffocate mites and it was a widely used treatment for quite awhile it can cause much more damage. Personally I would urge for a different treatment. The fact that we now know what oil does to their scales now makes it important that we try and use alternative methods like Pam and plain water. I've seen vets still use this method and lots of outdated methods for other things as well, and while I encourage people to trust their vets not all actually care for the animals they treat. They were taught some basic methods and use them. Because of her actual issues ATM though I would definately urge for a different treatment.
