It was only the second time i tried. I just thawed him real good and heated the head up with a hair dryer. The first time he struck at it and got a mouth full of forcep so he spent about 5 min opening and closing his mouth. Trying to figure out what went wrong i imagine. I went and heated the head up again while he was working it out. Then I offered it to him again this time he struck it and wrapped it. The rest was just like with the live mice.
