Hahaha. Thx all. Yeah she's very big and very kind. She's my pride .

But about growth ..... I had 2 concinnus females ... one was around 100 cm and very big. Her sister was smaller and shorter. It was a very large difference. The babies from both where also different in size. From the 5 females that where born from the big female even they where different in size. One is VERY big for it's age, but her sisters stay much smaller.
If you look at the picture .. she's 4 months old now, and the parietalis is from april 2011.

What I want to say is that garters, even the same species grow very different in size.
