I recently got a ball python from Petsmart (I know how bad it is, I didn't buy and it was 50$ off.) They didn't have a very accurate guess as to how old he was, besides a few months. He is about 17 inches long and weighs 77 grams. I believe he's been eating pinkies (Thats what the woman sold us, he should probably be on furries by now, however) Could anyone guess about how old he is? It'd be nice to know so I could pick a birthday for him.
