Thank you so much for the advice, everyone! I tried him again this evening, but only because he's my first bp and I'm a worrier! He last fed a week ago, but in the mean time he's had a three day journey and only two days in his new place. I wanted to try and keep him on the schedule he's used to, but I'm not surprised he's probably more focused on feeling settled and secure in his new home first! Will try again after Christmas.
