More than likely, your JCP just has the natural aversion to rats that many of us have to deal with. I have an 8ft plus female that will not touch rats. She does the same thing, grabs, constricst then releases. If I feed her fresh stunned she will kill it then leave it. I have to feed her 12 jumbo mice, or almost 20 large mice a week. I kill them all and drop them in her feeding cage and she eats them like a dog. You have the luxury of trying to get her to take rats. Sounds like your snake is young and the hardest part is offering nothing but rats from now on. Most people, myself included, give in and offer mice again. Usually, they will never take anything else. If you have the heart, offer it nothing but rats and eventually they will come around. This is hard on the heart strings though and most people give in. Remember, snakes can go a rediculously long time without food before they actually have any ill-effects. Their metabolism will slow and they will not usually drop weight for months without eating. My JCP has the strongest feeding response of all my snakes, and if I had the willpower when she was little to get her to switch I would be a happier and richer man. Good luck, Eric-
