I'm assuming you're an adult, & as such, I wouldn't let your mom, no matter how much you love her, dictate your pet choices. I've changed so many people's minds about
snakes doing programs & "meet & greets" with my friendly snakes- most of the fear is in people's heads & when they meet the real thing, assuming your pets are reasonably calm, that fear often melts away. Either way, it's not right for her to expect you to give up pets that you "love...so much and raised from babies". I hope your situation all works out OK & you aren't delayed returning. And I sure hope you don't re-home your snakes. (don't fall for any 'guilt trips' lol...you have a right to enjoy what YOU enjoy!)
