Do not assume when you make a purchase you're covered by some "normal warranty period."
I agree with that statement to a certain point...
I concur that it is the responsibility of both parties to hammer out the "What ifs" well in advance of the transaction being completed, and agree that it's not safe to assume that every animal has an identical guarantee or how longit should extend and what that guarantee should cover in terms of specific problems...
However there really is no need to get an advance guarantee that the animal isn't misrepresented.
Whatever an animal is sold as, it needs to be delivered as. There does exist a basic guarantee that extends to all sales that the buyer will get an animal that is alive and that it will be the specific animal they decided to purchase, meeting all specifications and descriptions (Mass wholesalers or shipping when it is clear in advance that live arrivel isn't guaranteed and is AGREED TO prior to shipping is a separate matter).
The customer did not purchase a dead animal.
The customer did not purchase a sick animal.
The customer did not purchase an animal two feet smaller than advertised.
The customer did not purchase the seller's mites.
The customer did not purchase bacteria or viruses.
The customer did not purchase an animal that is opposite of the gender that was indicated.
The customer did not purchase an animal that does not have the genetics it was represented to have.
The customer did not purchase an underweight off feed animal unless they were warned "This animal is underweight and hasn't fed because it was breeding, chances are good that it can bounce back to full with a bit of attention, but you need to be aware of it before purchase" after which it becomes their choice.
In this specific instance, the animal was advertised as being Healthy... there is a disagreement over that. It was advertised as feeding... there is a disagreement over that. It was advertised as hypo... that opens up a whole new host of questions, but there is disagreement over that.
The fact remains that a lot of those qualities that an animal can be advertised as having are somewhat subjective. I may not see an animal as being healthy when you see it as acceptable, the amount of experience a person has and the nature of that experience plays a huge role in how they view some of these terms that are used. That's a whole separate discussion that I think I might open up on the GBD forum, but it's relevant here...
When there is a disagreement about the representation of an animal and both individuals are being honest to what they percceive as the truth and neither is trying to "get one over" on the other, then it's an unfortunate reality but... the responsibility lies with the seller to correct that problem in a reasonable manner and to the buyer's satisfaction. It's what customer service is all about. I could see in this instance, where Greg wanted a refund... deducting shipping costs to have it returned, so that there's no substantial loss there, but I get the feeling Greg wouldn't have been upset if he had been offered $950 out of the $1000 he paid because he would reccognize it as his personal dissatisfaction (ignoring the unsubstantiated genetics issue for the moment). But a 25% cut on an expensive animal in punitive costs? That's absurd.
If the animal is healthy and feeding (or potentially feeding) and it's really an issue of buyer's remorse... then there should be no problem issuing a full refund and having the animal returned, because it can easily be resold to someone who's willing to take it at that price in that condition.
