This is what's on his website right now, not sure if this was in effect when the animals were sold.
==============================================
All animals are guaranteed live arrival, as long as there is someone at home at the time of delivery. If you are not going to be at home, please have me ship to your work, or on another day, when you'll be at home.
I also guarantee the health of all animals, as long as you contact me as soon as you notice a problem. All animals should eat within 24 hours of arriving at your home. Most will eat and drink right out of the box.
All animals are guaranteed healthy and eating well.
In the case of a DOA, I will refund any money paid minus shipping. Or if possible, replace the animal with another of the same or better quality. In the case of a replacement animal, the buyer must pay for shipping on the second animal. Also, I must be contacted within 24 hours of delivery, if there is an unfortunate loss due to delayed or extreme weather shipping. Proof must be provided of the DOA. Including, but not limited to: photographs, receipts, and shipping the animal back to me.
==============================================
Sounds to me like he requires proof for refund or replacement.
