Since people write up documentation that guarantees genetics of a heterozygous snake, why don't people write up documentation for desert females saying that they WILL produce viable eggs? The people who are selling them seem to be telling their customers that deserts are 100% fertile and that everyone will see soon enough... If they're that confident, why not write up documentation? If the snake doesn't reproduce, then a full refund is in order? I don't know how it would work... this is just a thought I had when I got to work ...
