your girl is definetly adjusting and exploring. two things to think about. 1, letting her crawl around the edge of her enclosure could promote this behavior. 2, if thats the case you would not be able to interpret the behavior as a food hunt or a desire to crawl around the tope of the cage. snakes have behavior and can certainly be conditioned in positive and negative ways. If she is handled or removed from her enclosure, move away from that area and when she is through exploring and doesn't get to crawl around the rim, she settle in. ezra
