Im a recovering drug addict, i got my first snake just over a year ago. A few months ago i had 47 total. Due to the 600$ + food bill per month i have down sized. Currently my burm is my second favorite snake. He is at 8 ft right now, puppy dog tame but i made a mistake once and let my cat into the same room as him. If i wsnt paying attention it could have been bad as he went for the kitty. They didnt touch fyi. I now ensure to securely lock the room i let him roam around in to avoid any trouble.
Being your in high school i would suggest not to get the berm. It takes alot of time and dedication to take care of these amazing animals. And although i said he was puppy dog tame that doesnt mean he is always in a good mood. If i didnt have the experience with smaller snaoes and reading them im sure i would have been bit by my burm by now.
Dont think of it as oooh cool a big snake all my classmates will be impressed. You could easily have a bad situation on your hands if you got careless or werent paying attention.
I would say go for it if your parents know 100% what they are getting into aswell as you, but then i also want to say pass on it.
