Why are they shipping it Friday? Can they guarantee it will arrive on Saturday??

I never, ever ship animals later in the week, because you never know when there will be a storm or a mechanical problem, which causes a delay. Ship Thursday for Friday delivery, if there's a delay, it goes to Saturday and likely will sit in the hub over the weekend.

ALWAYS get animals shipped on Mondays, Tuesdays or Wednesdays at the latest. Will ensure you get your animal.

I don't know why you just didn't buy from Kara @ NERD to begin with.
