Wait till you're out of the house. Get something you actually want. I've waited 6 years to be able to start getting my own snakes I want and I still don't have any. I will be getting some soon, but still it doesn't sound like your parents are endorsing a good way to look at it. Animals are living creatures that deserve respect and good care no matter what they are. Not saying your a bad person, but I really think waiting is your best option.
