Not to mention Axel is already an established f/t feeder. Granted he was underfed at Petsmart but still eating f/t. So switching to live this early I feel is completely unnecessary and over complicates matters. Live feeding would be better reserved as a last resort if Axel was refusing numerous meals AND loosing weight regardless of husbandry being on point.
Something else to consider is if OP did offer live, there is a chance (not gaurenteed but still a risk) their bp would no longer accept f/t and that would be a new commitment OP would have to get into.
Since they still live with their parents this could be harder because live feeders are not as easy to obtain and keep, and on the occasion OP has to move out, some places, room mates, land lords, dorm rooms won't be cool with OP keeping a supply of live mice, let alone a snake. It just makes things harder if OP can avoid it. Plus, husbandry should be the first thing to consider looking into before changing feeding methods.
I just think it's way too soon to recommend live so casually when their bp is still in the process of acclimating.
