Approximate age?

[snake_girl85]

I've decided to keep a spreadsheet of Oogway's growth, using the format from africantortoises. I got him from LLLReptile at a show in Chicago on Valentine's Day, and I forgot to ask how old he was. My rough estimate is that he is around 4.5 months at the moment, but I really have no clue, and the chart on africantortoises starts at 6 months or so.

I work at an animal shelter, and we estimate the age of stray kittens based on weight. Can anyone venture a guess as to how old Oogway might be? He is currently 45.2 g (before feeding) and approx. 2.25 SCL

Thanks!
