Not only are ball pythons not good climbers, they're TERRIBLE climbers.

In fact I think some of my BPs dont even understand the concept of climbing because there have been times where they just kept stretching out until they fell down completely. The only climbing I have known for one to do was when he was trying to push the top off his tank and he was climbing on this hand towel holder I used to have for him to climb on ~_~ and he had this tendency to knock it over with him, causing him to fall in his water dish... every day... at 2 am... for 2 months...

Sorry every time someone brings up BPs being bad climbers I have to throw in my two cents.
