Was it a Mojave from a pairing that included Leopard?
A lot of new keepers have selective memories once they get home after having an excited conversation about a cool looking animal with a breeder at a show. They end up thinking the animal is carrying more genes than it actually is because that conversation included talk about the pairing that produced the animal. Many times the buyer thinks they've had one pulled over on them when that actually isn't the case at all.
Since there's almost no way a breeder with a shred of integrity/experience would confuse this animal with Leopard anything, I have a feeling that a simple phone call will clear this up pretty quickly. I certainly hope this is the case for everyone involved.
Best regards,
Eric
