no interest in his food.

for the first time in almost a year my BP refused a second time in a row, he eats a bigger end of a small rat or a small end of a medium, basically depends on what the place has, usually feed every 14 days, so 8 days ago he refused to eat, was more worried about wanting to come out and say hi, tried again yesterday which was 7 days after the first refusal and could really care less i was trying to feed him, we feed F/T btw, nothing has changed in his aside from larger hides a few months ago, same temps and humidity as its been when he wasent being picky, anyone have any tips, also i know they can go a while without eating but how long is too long? thanks in advanced.

They can go months. I've read about many BPs going longer than 6 months and if I remember correctly 8 months was the longest I've read about.

Anyway, nothing to worry about. As long as the snake isn't losing weight don't sweat it.
