This climbing seems to me like the snake is most comfortable at the coolest part in the cage obviously. If she is always there, my gut feeling would tell me the overall ambient temperature is too hot, leaving her unable to use a comfortable hide on the ground and take advantage of gradient temps. Call me crazy but most balls are comfortable in the 78-83 range. They will do fine in 90 degree tanks, but I do know when they are given a choice, they settle in around 82-85 degrees to bask. Most new python keepers seem scared of temperatures below 80 degrees. Truth is, they can really be comfortable there. In 20 years I've never seen a Respiratory Infection. Anyways, very beautiful snake there. Just wanted to shed some of my experience.
