There are very few and they are spread out, but along my ball pythons spine are some scaleless spots that seem to have traces of dry blood on them. I'm thinking this is because I have very large cave decoration that I can't lift up without taking the top of the tank off, so when I go to get her out of there, it might have torn off some scales on her back. Will this normally go away on it's own or should I sanitize it in any way?

Also - she is in the process of shedding. Her eyes turned a bright foggy blue a few days ago and they're darker today. There's some patches of dead skin and almost all of her body is flakey, mostly her underside. Is this normal and how long will it take for her to shed? This is my first snake, so I don't know what to expect.
