I am not at home currently but I do have respected references for climbing ball pythons, that can and often will if given a chance. Nothing is wrong a ball python that spends some time exploring and or climbing whatever. Mine spend a few hours day 3 days a week doing stuff outside the hides a day or two after feeding days... The range of natural behaviour is restricted. My balls in tubs behave differently that the ones in naturalistic enclosures. I am not saying unhealthy just they don't display the same range. I believe that a ball python that hides 99% of the time is not normal either and when I am home I can provide references for this as well.
