I've seen a lot of people keep "sticks" of some sort in their BP's enclosures, on the off chance that they want to climb a little. I haven't had any luck finding anything though (nothing is coming up on my google search for "climbing stick for ball pythons," lol). I know about driftwood, but I want something more "stick-like", rather than all branchy and weird like most driftwood tends to be. What do you use?
