Thanks for all the suggestions! I didn't leave it in overnight. I don't think she would have eaten. She's been home since Saturday, the breeder told us to try feeding her in 2-3 days. Which I should have known to wait 7, but we decided to try.

When he was showing us the snake, she hissed at him about 3 times when he picked her up and was just turning her around so we could see her. My BF had a gut feeling that she might be a picky one that would give us trouble, but didn't share that feeling with me. Does anyone think this might be the case? I didn't ask for a feeding record cuz he said "Well we have so many babies we can't keep track" So I'm gonna call today and ask again in case another employee knows. After all, she was the last lemon pastel, you'd think someone would remember.
