i remember that the same thing happened the AKA Dave's BP - https://ball-pythons.net/forums/show...w-what-do-I-do he's BP eventually came out and i hope your's does too. i have the smaller version of that tree and the smaller one doesn't have holes in it's base. plug it w/ aluminum foil or canned foam instead of newspaper b/c paper can mold.
Edit: also i would not leave a rat to defrost in the enclosure to entice it. your BP would be in trouble if it were to swallow a frozen or partially frozen rat/mouse. leave a fully defrosted one only.
