Lol, it's cement flooring so if they fell, I'm guessing they would die. I'm also worried that if one got out and fell on the floor that would be the end of that. So far I've been able to overcome my reflex to let go. It's not even like it hurts when a bp bites you, but it definitely startles you!
Oh my gosh I never thought of that! They definitely like to launch themselves when they are babies! Now I'm slightly more worried, lol. If my floors were carpet I would be a little more relaxed about it. I'm sure they are hardier than I'm giving them credit for, but I definitely think the foam flooring was a good choice. It's the big black interlocking foam pieces.
