I think she's just a quick grower, I did feed her cut pinkies/fuzzies etc when she was smaller; that made a big difference in growth.
But yes she's big; that was why I did slow her a bit down; I dont want her to grow to fast or getting fat or unhealthy.
I do let her grow this year and hoping she will give me some nice babies in 2008 after a good brumation (with some heavier feeding I think she could be ready this year; but I dont want to harm her in any way). Her future mate is still very small.
Next month she will be housed in a larger and more natural viv, giving her some more exercise
