FYI- When a vet says a snake is in good health, they only mean as far as what is obvious. That doesn't mean there is no need to quarantine, because what snakes get sick & die from are all those tiny things that can't be seen. (germs!) Don't read too much into that reassurance.
That's fair!
But I still made sure that she was in a clean bill of health before getting my other snake, and even then, I kept him in a separate room away from her to make sure he wasn't sick either. They're both thriving quite well!
