Move out. Lol!
My mom hates my snakes and doesn't understand them at all. Luckily that's no concern to me because.... My house my rules.
Just be glad she's letting you have it. The Blonde Hognose I got a few months back was bought from a guy that bought it without permission and when he got home his mom said, "NOPE!" I was nice and paid him what he spent.
So it could always be worse.
