I'd venture to say that just about every vendor is trashed on fauna. All I'm saying is don't judge or spread negative word about vendors you have not dealt with personally. Underground's animals in their shop are in fine shape and, as I said earlier, my animals are thriving.
I prefer to take a stance of better safe than sorry. I don't want to risk getting a sick animal, regardless of how many good transactions they have had. And not every vendor has been trashed on Fauna. There are plenty of good breeders who have no negative feedback.
