You should NEVER feed a giant constrictor outside of its cage... you are just asking for trouble trying to move a huge snake that has just fed and is still in feeding mode... and how old are you again? How do your parents feel about having a giant in their house? It might be a good idea to either wait until you are on your own and able to have a giant, or make sure that you have your parents approval and support no matter what. Personally, I think you should wait and do TONS of research and hands on work with a giant before diving head first into it. Good luck!
