If a 15 yr old is responsible I see no reason why he shouldn't get a bp if his parents are on board with it. I have a friend who's son is 13 and is responsible for quite a bit of the snake care now....and does a great job with them.
I've noticed some pretty negative responses in this thread and don't quite understand why. When someone comes here with a question jumping all over them and calling them "kid" is not a very productive way to respond.....btw your age still ends in the word "teen".
Tiff is younger than the OP and I think she does a wonderful job and shown responsiblity with her animals. It's not like it can't be done.
When I was 15 I was caring for approx 30 herps at a local Nature Society and doing educational things with youth groups there. If you had told me that I couldn't handle one bp due to my age at the time I would have laughed in your face. Some people in that age group are better off waiting to make sure it's not just a passing fad and I think that everyone should have a back up plan just in case it is just that.
