Answer
Susan -

Flea collars usually do not work and can be toxic in cats.  That could account for the constant licking.  The flea collar can severely irritate her skin causing her to chew and lick frequently.  

I am not quite sure about your question; if you will please clarify your question I will be happy to try to help you.
