MAYBE it is an assumption But I do not think many realize a snakes ability to grow or not grow.. There are many other collections where animals are no where near the size of mine.. Yet they are healthy and well adapted to that particular program.. In the herp world there are MANY questions that are un answered and no factual information is available.. For instance I can take 2 female animals of the same clutch and grow them differently.. In a 3 year time frame I could keep one at less than 4-5 pounds while the other would be well over 20 pounds.. Popular opinion would likely say the big one would have a shorter life span.. BUT again there is no factual study to prove that.. A young animal is supposed to grow, how you maintain it after the baby growth time would in my eyes determine it's longevity.. Snakes are amazing creatures and even those of us who admire them have mis conceived notions, But that's what makes us Human.. I like big so I foster big, he likes small so he fosters small.. Then there's that person that say's were both doing it all wrong.. My apology for not putting a said size down but I have not done a study to give you a Factual answer other than smaller than mine.. Bloodlines and locales also differ some just like people, dogs and horses..
