All the more reason. If you are scared or concerned about their reaction then you know their answer. You have plenty of time....don't rush it. Your parents have allowed one snake in their home. They probably are doing a decent job of feeding, housing, and providing a loving home for you. The best way you can pay them back is to show them respect. If that means putting your dreams of breeding a new morph or simply breeding your own royals then you are just going to have to wait. I know...it sucks sometimes being a kid. It also sucks sometimes being a parent.

By all means talk to them. Keep it open and receptive to answers you may not want to hear. Thats life.
