I have that same log I got from PetSmart in my 20gal! My snake absolutely loves curling up in it and just so happened to be inside of it during feeding day. I had to stick the mouse in there using my tongs and he struck at it. I've heard of people using the same logs and said their bp's wouldn't come out for days on end and miss their feeding day. I guess it depends on the feeding response of the snake. Maybe try removing the log and replace it with another cave type.
