Is there any way to get an approximate estimation of the age of a sulcata if you dont know its birth date? I am thinking about buying a 26"sulcata from an individual. He has only had it for 6 months. He knows nothing of its background history. He says he thinks it looks pretty young. Im thinking it could be anywhere from 10 to 25 years old. Are there any other physical characteristics that can help me get an idea of its age?
