how do i tell how old my ball python is??

Answer 1

There is no definitive way.
Even size isn't a very good factor in telling the age of reptiles. It depends on how well he eats, how often, even temperature has an effect.
Best bet is if you got him when he was still small (think, 18" or less), than he was a few months old, then go from there.
