My bp was doing that the other day more than usual and I figured out it was because the temp in my room had gone up and was making the tank warmer. Are the temps still the same? Orochimaru likes to climb up the tank and fall off, especially on feed day. It used to worry me, but he doesn't seem to mind falling. Maybe she is just hungry. I actually always clean the tank on feed day, so I take him out. Normally I put the mouse in there only a few minutes after he has been back in the tank. But my snake loves to eat lol.
