Since I don't live with my parents anymore, I just get them well, without their permission. I have my own apartment and my landlord is OK with reptiles. I told my parents initially when I got a snake and they told me to take it back. But I wasn't about to take the love of my life back.

I have 2 more snakes and soon a crested gecko they still think I have one snake. What they know won't hurt them. I suppose since it sounds like you are living at home, you should get permission since it is her house. Good luck to you! I have found getting a snake to be one of the best parts of my life
