True statement as Eddie agreed, Not only does it apply to Boa but any other snake as well..A burmese need not be a monster if fed per schedule..This is one of the many great features of snakes..While one could call it stunted another will say maintained for longivity..If one is out to achieve size on an animal it is best to do so before 18 months of age..While the animal is a "baby" per say ..Feeding and growth an everlasting debateable topic that boils down to ones intentions or goals..
