Yay Danni!!! My hubby won't let me have venomous cause they are too dangerous! He says having a loaded gun would be safer! Phfff. Oh well he always has been a reptile lover and does want a hognose. So I told him if he gets a 'poisonous' hognose I can get a pit viper LOL
I would just find a common ground with your gf. Maybe just don't have larger snakes until your kids are bigger. There are plenty of dwarf boas that are amazing snakes that you could have instead of a BCI thay she may be okay with! Just a thought but of course it's up to you.
