Ball python age...

[Eric Alan]

If she was fed a lot she could be a year old, if she wasn't fed well she could be 2 or more years old. Size isn't a good way to guess age because it all depends on how they were fed.

Exactly. For perspective, here's how old my four (very well cared for) girls were when they reached ~738 grams:

• Butter Pastel - 1 year
• Enchi - 7.5 months
• Sugar - 10 months
• Spinner Blast - 1 year

We can all guess as to the age of your BP (and perhaps come close), but in all honesty we have no idea. It's like trying to say how much a 150 pound person is without any other information.
