Im not trying to be an opposing force against you and Im surprised by your comment. I didnt think you had an issue with me or I with you. I have not agreed with some things you said and obviously have different experience and different style to my keeping but I didnt think Id rubbed you wrong. As to Balls climbing I just don't agree with your statement that a BP being stressed or experiencing husbandry issues being the reason for climbing.
Your snappy comment about me needing to "study the species" is a bit out of line as well. You were presented with facts by others with wild snake observations. Where are your facts? You have not presented any and instead decide to shoot off at the mouth with cute comments to other keepers that did provide information and those that have seen the action in question first hand.
How bout you place your Balls in a cage that they could climb and see what you experience. I have seen your video and pics of your snake room and your snakes don't have anything to do so I bet that is why they do nothing. Its hard to do something when you do not have the opportunity. Your tubs are bare, small, and short. You can see my collection and see that I have true arboreal snakes. I never said my Ball was like my GTP, ETB, or even my BRB which is a great climber.
I can guarantee my Ball is not experiencing any stress and her cage is on point. She has the best tstat and has one of the nicest setups on the forum. I have not gone cheap on any part in any area of my keeping. My snakes have nice cages, proper tstats, and proper heating in their own heated room. They all have a great life in my care and want for nothing.
You ever seen a GTP or ETB coiled on the ground? I have. Just as those two can come down and relax on the ground a Ball can just as easy take a bit of a climb. My GTP and ETB also really enjoy swimming in their water and when up and active at night usually will take a trip around the cage floor and through the water bowl before going back to a perch. Seeing them swim so often really showed me something I would have never guessed. So just as an arboreal snake can slither on the ground there is no reason to believe a Ball Python could not take to a tree.
I think it would be interesting for you to put some of your Balls in taller tubs with some things to climb on and see what your snakes do. They may teach you something.
