You're very lucky, it looks like she just lost some skin. Make sure to change the paper often to keep the environment clean. It should heal up just fine in a few weeks as long as you follow the care instructions people have posted, and after a few sheds you probably wouldn't ever know she was injured.
Definitely will. How many times should I disinfect/apply the polysporin? Once in the morning/night till I see the vet and see if she says differently?
