i have my drum kit in the room next to my snakes but more towards the front of the house away from where my snakes are. i kill that thing and the snakes dont seem to mind at all. they eat, shed properly and breed. i even play during lock ups or in the day before i feed and everything works out fine. i even have guitar amps and jam with buddies and the snakes dont seem to mind it.
i used to worry about it but my g/f told me she saw them head banging one day so im pretty sure they actually like the loud music.
