This person replies to Craigs Lists posts with text messages inquiring if "still for sale" and then cites the ad line.  Within 24 hours you will receive a text saying "Hi, I'm okay with the price and condition.  I will pay you with Cashier Check as its the only way I can pay you at the moment due to the fact I am away for a business emergency.  I will make arrangements for the pick-up after payment have been received by you.  I don't mind adding an extra $50 just for you the keep it in my favor.  If you are okay with my terms please reply with your full name and addres"

Since this person is responding to an ad for a LIVE ANIMAL that has never been seen it is very suspicious.  BEWARE!
