Our male 100% het from 8Ball was born on June 26/05 so that puts him just 2 days shy of 9 months. We got him Nov 1/05 at 145 grams, he is now 480 grams so that's an average of 67 grams per month in growth weight wise.
Our female snakes we got at varying ages so harder to get a fix on growth patterns as much with them though I have noticed that for some reason when they hit around 800 to 900 grams they seem to go on this growth spurt/feeding frenzy thing for awhile. Very fixated on eating and not much else and tend to be a bit spazzy for awhile though pack on steady weight as all they seem to want to do is eat. They seem to settle back down a few hundred grams later and return to their more normal patterns. I think Adam refers to this as their "teenage angst" LOL
