Welcome to the forum!

Here's a good article on The Shedding Process: http://ball-pythons.net/forums/showt...edding-Process. Each animal is a little different, but they all tend to follow the pattern in that article.

It sounds like you've got everything under control, so I wouldn't stress too much about a single missed feeding.

How long have you had Violet? How old/big is she? Is she a morph?
