Unless you are feeding for breeding, you might try introducing a prey size that produces a small bulge in the snake's body. The bulge should go away in two to three days. I've done that with my 21 month old BCI and he seems to be doing well. I learned that system from a top breeder on line who does a lot of educational videos. He does not weigh either the snake or the prey. All snakes are different so just take this as something to think about. You have a beautiful snake with a healthy rectangular body. Thanks for the great question!
