Hard to say really. I know Emi still does the climb and thump routine in her enclosure but she's just a baby milk. Rauri the big BCI never falls but at his length he can pretty much reach point B from point A anytime he wants. Our ball pythons aren't big on climbing except Kyna. I think is convinced she's part tree snake so we do have to sort of spot her occasionally as she's pretty clueless about the whole concept of "gravity works!". She's a bit over 2 years old. The older balls seem to be pretty savvy about most things and can easily slither off the couch to the floor or on and off the coffeetable without incident.
