My albino male used to do the same thing. He would strike, coil around it for AGES, and then leave it there. I kept being told (not here) that it he was uncomfortable which is why he wouldn't start to eat it. (I feed outside of the tank in a feeding tub.) Bollocks. I thaw my rats in the fridge over night, then I boil water in the kettle and put the ziplock baggie inside a mug with the boiling water. I usually do this right before pulling him out of his tank, you have to be careful you don't want to cook the rat. Even then with it super hot he won't eat it. I have to dip the head of the rat in the boiling water for a few seconds, dry it off and he will strike every time within seconds. He still takes forever to uncoil and eat it but he has eaten every time since. *knock on wood* Good luck!
