Thank you both for the advice. Yes she does have one somewhat large piece hanging off. And yes she has plenty to rub against that would be rough enough to help.
As for her eyes, I notice yesterday that they were much brighter black then the dull the had before. Again, being new to this, I am sure she had been in the pre-shed mode prior to me being aware of it.
The link posted about what to do for a bad shed seems pretty easy to follow and if by tonight she hasn't shed fully, I will try that!!
