Mine started by not eating anything offered, no matter how long I left it, so I had to force feed a few times, after that, he struck at ANYTHING that I put in there. Since I switched from pinkies to fuzzies (which should be NO PROBLEM for him, I'm pretty sure he could eat an adult mouse) he has been a little bit of a shy eater. I don't keep him on an exact schedule (but it's usually 6-9 days and I'm well aware of when he was fed last) but I wait until he starts hunting around the cage. Once I've seen that a few times, I'll offer him a mouse. I can leave the mouse in front of his nose and he will sit there ready to strike for HOURS. Finally I just go to sleep and it's gone in the morning. I've started just leaving it for him before I go to bed, that's why it's nice that I feed F/T, I wouldn't be able to leave a live one. (Not sure he'd move quick enough to catch a live one either...)
