The white scales COULD possibly be scars if she was feeding live and they bit her. She looks fairly young, so I don't know how much damage a rat/mouse her feeding size could do, but I'm sure enough that it's the possibility of scars.
One of my females got bit REALLLL bad one time cuz she had horrible aim and after a few sheds now you can hardly tell she has a lil scar.
How long have you had her? They could go away with time.
Ace I've had her for 2 weeks now. The guy I got her from says she's 2 months old but I don't know how true that is all she has ever eatin is f/t I don't think they are scars it almost looks like the color is just gone from the scales but then again I could be wrong.
