Wow...always thought cobras were awesome looking snakes, but too scared to ever get one...Can't you (technically) get a posionous snake de-venomized? That way if she ever did bite you it'd just hurt like hell instead of possibly killing you???
Yes. There is a procedure that can be done which removes the venom glands from the snake. That being said it is considered to be animal cruelty to almost every herper. I would never have a hot's venom glands removed. If you can't handle having a hot then dont get one.

Vials of anti-venin can be in thousands of dollars a vial and many times more than one vial is used to treat a patient.
