By white do you mean she is kind of faded? If so she is going into shed. She will shed in pieces. You will see pieces of loss skin on her but do not pull it off. You could just give her another bath and the humidity will help her in the shedding process once you see this start to happen. The tail, legs and head will probably be the last sections the shed will come off. As far as her side bars changing, what is the temp of her enclosure? What type of lighting are you using?
