also I just re-read your post to make sure I didn't miss anything. Please don't feed any snake hamburger meat. It's very bad for them, because all it is is muscle and fat it is not a nutritionally complete food item and very fatty. Snakes need to eat whole prey to stay healthy, with bones, teeth, brains, organs, skin and muscle. It would most likely cause a regurgitation and/or a very smelly, greasy poop! Yuck :0

I wish you the best in finding a snake that is right for you!
