BPs hate screen-top cages? o-o I put a towel over 90% of the screen, does that help? my snakes have branches and rocks to slither over... my female has a plastic branch suctioned to the wall of her tank, she used climb on it but rarely does anymore. Their favorite thing to do is do from the hot to the cold side, back and forth... lol. Most of the time they sleep on the hot side (in their hides) because I have a slight temp drop at night but keep the under-tank heaters on.
