So your basis for determining if a snake is underfed is its weight and age? I assume from your opinion that you are focused on how fast you can 'grow' a snake.

My opinion is different.

My basis for determining if a snake is underfed is based on appearance from my experience with reptiles. Who cares how old a snake is if it does not have the appearance of an 'underfed' animal? If the animal looks like it is well fed....then fine with me.

Just sounds like a simple difference in opinion to me....but if weight and age are so important, why not factor in length for every snake? Judge 'underfedness' on an average weight per unit of length per age.
