I've had my male green just over 4 years old and he's betwen 11'3" and 11'9". I feed him a 450-600 gram rat once per week, and I'm hoping this isn't too much.

Browsing through a book called What's Wrong with My Snake, I found a passage in which the authors say a sign of obesity in large snakes is their scales creasing when they coil. My male green's scales crease, and then I realized I may be feeding him too much. The rats are much less girthier than the snake is, so I assumed I wasn't overfeeding.

Anyone know a feeding model for greens, for particularly the males?

Thanks!
