Sheri - my calico, Patches (Rainbow Bridge) talked to me constantly. And yes, it can drive you crazy. I suggest that you talk to her - after you are sure nothing is wrong and she is trying to tell you something.
Talk to her about anything - what you are doing, how you feel, where you are going
and when you are going to return.


Many cats are talkers - and very social.
The biting if it isn't too hard, is affection she is trying to give you. Sounds as though she loves you very much and wants to tell you all about it.
