Alright i changed the substraight level from 9 inches to 4 on the non pond side, i then cut an 11 3/4 inch wide by 9 inch tall sheet of plexyglass sheet and slid it inbetween the pond area and the burrowing area, around the 1.5 inch gap around the pond i added large river rocks to prevent burrowing around the pond. i also added a second flixible heat pad to the side of the cage in the burrowing area and unplugged the heating cable all together.
