While it is true (so far as I've ever heard) that they never actually stop growing, it is not true that shedding indicates growth. They can shed for multiple reasons, not just outgrowing the old skin...primarily, the old skin just gets worn out and needs to be replaced from time to time. As mammals, our skin replaces itself constantly...theirs has to be done all at once.
