I am new to the whole world of snakes. I have 2 ball pythons. One is a baby yet. We know when she hatched. However, our male, whom we rescued, age is unknown. Is there a way of estimating how old he could be? The guy thinks he might be 3 years old. I realize there is no way to determine exact age, but would be nice to estimate how old he might be. He is a little over 4 ft and weighs 1850 grams.
