Yes, both of my boys balls did that. They only eat live and are very happy! I will not stress them out and change to f/t, in nature there are no f/t prey.
My concern with live is I have had one of my bp's bitten by a rat when she grabbed it wrong. Poor thing had a scar after that. To me, as long as they eat, I don't think it matters to them if its live or f/t. If anything, its just easier on them, less time constricting
