I've only ever had one arrive about 6 hrs late, and after about an hour I started calling FedEx every 30 mins to the hour to make sure they knew I was waiting for a live animal and I was pissed. After the fourth angry call, they rerouted the driver to send him straight to me next for the sake of the animal. But that was a shipping delay in which the package was already out on the truck and may or may not have made it that day. It just kept getting pushed back. If it was at the hub, I would have gone to pick it up. Where did the delay happen for your animal?
