At what age do they stop growing?

Ok I gotcha. That is helpful info, and picture, thanks!

Here's another five foot boa. She's almost three and a half years old. At five foot, they are already very strong snakes. Like Gio said, it makes them seem bigger than they actually are. I honestly believe that most people accidentally exaggerate their boa's size.

Anyhow, they all grow differently, but as others have said, it's pretty hard to underfeed a boa.
