Digesting Food

[unknownclown]

I was just wondering how long it takes for a boa to digest a rat. I fed my BCI a rat sunday that was a little too big for him cause it was all they had available and he was going on 2 weeks without eating since he has decided that baby bunnies arent as good as he thought they were last month. He hasnt regurged which I was expecting (heck after the first time he did that Im scared he will do it with every feeding). He hasnt hardly moved since I fed him which is normal but theres still a noticable lump in hid belly. This is only day 3, is there still the chance of him regurging or would that have happened by now if it were going to?
