I'm so sorry to hear that!My parents have always been wary of my pets, but they got used to them after a few years (though my dad is still not at all comfortable with my boas). It's a tricky situation to be sure. Maybe you could compromise, say you'd keep the five snakes you have but not breed them. That would eliminate the need for more racks and incubators. If not, you could sell them / give them away to someone local so you can keep an eye on them and maybe buy them back once you move out?
