Ah, all good info. I will run stuff on craigslist. I think we are for having pet rats now (my son is into it, my other son is the one who 'owns' the snake) so the cage won't go to waste regardless.
And I didn't specify the sex of Lucky when I got her because at the time she was just Viper's snack.
Lucky is still pretty small, got her as a hopper, but I'm guessing they can get pregnant shortly after weaning?
