My JCP was just like that. I put a frozen rat pup in a bag with a bunch of frozen mice hoppers and did the ol shake and no-bake. After a couple of minutes, thawed out the rat pup and hit it with the blow dryer. My JCP sniffed at the rat like a my yorkies sniff around and grabbed it while hanging on his perch. Never had a problem with rats again. Btw, will probably be in the same situation with you pretty soon. Just got a new pinstripe that I will eventually switch over to f/t rat pups. Hope this helps.
