Corn Snake growth

Question
Hi.  I read a post here that says if your corn snake is 4 feet long at a year and a half, that it's unnatural and unhealthy and probably has been powerfed.

My corn is abotu 16 months old and is 34 inches long.  He's probably a little thicker than a Sharpie marker.  He's been eating 2 fuzzies about every 7-8 days.  Am I overfeeding?

Also, when could I expect him to get to full size at that rate of feeding?  

Thank you for your time.

Answer
He sounds fine to me.  Juveniles can be fed newborn mice every 5 to 7 days; adults do well on large mice once every 2 weeks but can be fed weekly. A general rule for food size is that up to 1+1⁄2 the snake's body girth is acceptable. Corn snakes also readily take a larger number of smaller meals, and have been observed to swallow up to four smaller-size rodent pups (less than the snake's girth), in succession over less than 30 minutes. Thus, as a Corn Snake grows, smaller food items are not necessarily outgrown.

Usually in their teens they will peak at size.
