I'm pretty certain that according to the terms of the live animal shippers contract with FedEx, there are no refunds for late/delayed deliveries ... same way that they won't honor any insurance claims that you make against a lost or dead animal. If you read it carefull, you basically waive your right to on time delivery when you agree to the contract.

Not sure how things would work going through Repster though, so maybe you have a shot?
