Ah, congratz! I see you took my advice on using Aspen to. Do you like using it?
I only worry about how messy it's going to be when he goes to the bathroom...

P.S. For future reference, I wouldn't recommend leaving a live mouse in overnight... Luckily he took it in 20 minutes, but anything larger than a fuzzy mouse should be supervised when feeding live. Don't wanna get your snake all bitten up!
Sorry my version of overnight is a little different than most. I'm an insomniac, so Petrie(thats my baby ball) was fed at like 4am. If I were to leave it in "overnight" it'd probably be if I was able to nap for an hour or so.
