my new bp's previous owners fed him live, so after 2 live meals with me, i switched him over, when i fed him today, his strike was off 3 times. he missed the F/T rat twice, his husbandry is spot-on since i got him and he seems fine when i hold him, also when i fed live he didn't miss, is this a problem of him not sure if the F/T is food or not yet
