I'm in the same situation with Auryn. Except he was eating F/T for almost a year, abruptly stopped eating...and I tried for weeks, tossing out my Rodent Factory mice because he wasn't having anything to do with the F/T. I tried a live one on a hunch and he went for it immediately. He's going to get live for awhile until I've put some size on him, then we're going to try for F/T again.
