First, before every 13 year old emails me with threats (more like tantrums at this age) I have MANY reasons why a 13 year old should NEVER own a large constrictor like a burm:
1) Maturity: these are GENERALIZATIONS but most 13 year olds don't have the necessary experience to properly keep a burm. Keeping large constrictors takes YEARS of experience and one must have a keen eye for detail. Most kids simply underestimate the strenght of these animals and most young people simply are not at a stage in their life to take on this responsibly. Studies have shown that a young person's brain that controls impulsiveness/maturity/ability to make sound judgements doesn't become fully developed until you are 21 years of age.
2) RESOURCES: most youngsters are too young to hold down a job. Who pays for the food and upkeep of this animal? What happens when it gets sick? I can tell you, most people cut corners and end up asking for veterinary advice on forums like this and end up getting HORRIBLE advice (sorry burm forum, but I have seen some truly idiotic advice in recent days).
3) SECURITY: Although it sounds like your parents are supporting your hobby, that does has its limits. How much experience does your parents have in keeping large constrictors? If that experience is limited, then you are not showing good judgement. Are you putting anyone in your family in danger in keeping a burm? Does a brother or sister (if you have any) have any trepidation on knowing that a large, life threatening animal like a burm is under the same roof? If so, you shouldn't have one.
4) SIZE/AGE: Young people are on average not as strong as older adults. What precautions have you taken in keeping this snake responsibly? What will you do if you do get nailed by your pet? What emergency procedures are in place? I guarantee you one thing, if a large burm gets a hold of you w/out anyone else around, you are DEAD. ALWAYS HAVE AT LEAST 2-3 FOLKS WITH YOU AT ALL TIMES WHEN YOU ARE WORKING WITH YOUR BURM.
5) COLLEGE: I hope you are considering going to college. Who is going to take care of your giant snake when you are old enough? There are very few outlets for unwanted adult burms.
I am sure you are a very able and conscientous person who truly loves reptiles. I am curator of a very successful wildlife center that has MANY reptiles including large constrictors like burms, retics, etc. I also have many 13 year olds who help me out but they know that no matter how much knowledge they have, they are not ready for a burm. MOST BURMS kept by young people will become an abandoned pet at some point in their life. Do you want to be a part of that statistic? You have a real impressive collection of boas/pythons and they will give you the training you need to tackle a burm when you get older, have your own place and a full time job....of course, I am assuming that you are practicing sounds and responsible husbandry and management techniques. Good luck.
