when i got my royal, i was told to feed her every 7 to 10 days which i knwo alot of people do.she hasnt eaten yet as i left her a week or so to settle in,and then she went into the shedding cycle so il have to wait untill she sheds to feed her(hope she sheds soon)
try feeding him thrusday, and if not then wait until sunday maybe?give him time to digest the last meal he had,if you can still see a lump in the body of the snake, then leave it a few more days before you try to feed him again.
