lol fedex in my town is a joke. I've had parcels sit up there for more than a week without even an attempt at delivery or even just a phone call. They take care of business customers first and resedintial if they have the time. on one shipment I watched them stop at the school half a block away. I only use them for stuff that can wait. So I wait then I bitch and I get my shipping fees back.
This is just my experience in my town. I personally would never use them for any animal.
