Sure! First, I'd wait a little longer than he's used to waiting between meals before trying to feed him. If he normally eats every Saturday, give it a week and a half or two weeks instead to give him time to settle in and build an appetite. Then for his first meal with you, I would try a stunned or pre-killed prey item and see how he does. If he takes that readily, then I'd do it again another couple of times, then introduce the f/t when he's used to eating already dead prey. I just switched a 4.5 year old over from live to pre-killed and am going to try feeding frozen next and see how well that goes myself. All my others readily eat f/t mice.
