Just to chime in, I have been bitten by hatchlings, but they're so tiny that it did no damage whatsoever. Kinda tickled. Didn't hurt, or even break skin. It's probably more of a conern when they're bigger, but as long as I remember to wash my hands after handling my rodents it shouldn't be an issue. I forgot a few times and that's the only reason I got bit.
Definitely listen to Deborah when it comes to their care. She has a lot of experience with them and the information she's posted here in regards to them has helped me care for my own collection. My yearling girl-- well, I keep calling her that but she's not quite a year old yet. I think she was born sometime in May-- already weighs about 70g empty. They really are eating machines and she's grown like a weed since I got her. I just recently moved from twice a week feedings to every five days. She'd probably eat a mouse every other day if I let her, but I figure it's time for her to slow down.
*this was taken months ago, so she's actually bigger now
As for being messy, they poop pretty often. But it's no more messy than when any other snake poops. Hope that helps!
