I had to fight my vet to get treatment for my animals. He consulted 2 board certified reptile experts who agreed coccidia only needs to be treated if there are symptoms or a heavy infestation. As a breeder I don't agree but it is more of a matter of reputation than a necessity I can prove.
Snakes are not regularly imported and have been in captivity for more generations with the morphs etc. I'm sure you far more about their culture that I do. I haven't kept snakes in decades. I'm sure the treatment is already a part of the price. This is a new thing in chameleons.
I will have to pay out of pocket for the exam and any treatment. If I don't make my money back there is no reason to breed or sell at all.
Keep in mind I'm just tossing out ideas for others. I treat my adults prior to breeding. The problem is for people who buy or trade pregnant imported females. They are like already infected and the eggs or babies will be as well.
I think for educated consumers like yourself that is a possibility.
As an example my chameleons imported wild caught sell for ~150$ each. Captive bred sell for 175$ not including shipping. It would almost double the price. I would do do my own fecals and try to get a group rate for treatment as needed and then you are suggesting get an independent exam for certification. Interesting. It's the vets certification that is going to be a set price.
Okay, well let's clear the air on that one. You are bringing to the table several different situations.
I will agree that Vets seem to have mixed feelings on the Coccidia, I wouldn't sell a Cham with it myself.
However you shouldn't have to treat every baby. You should only have to keep your collection clean, and as stated Microscope your own Fecals. Treatment on a massive scale, should never happen with proper Quarantining of animals. If you let it spread to your entire collection, that's YOUR Fault, and that's your problem to deal with. Business take losses, that's a fact of being in business if you can't accept that, then you should not be in a Business.
Now that doesn't apply to your further example of a WC mother with infected eggs. That is a completely different situation. If an animal comes in, and is gravid with infected babies, those babies can be sold and shipped infected.
That's okay, that's Okay because those animals are NOT Captive Bred, they are Captive Hatched, are no different from WCs and should be treated as such. If I buy a WC animal, I know it's going to have problems, I have factored that into my descion to purchase it. That does not apply to CB animals. Where prices are higher and so are standards.
The same applies to lower priced breeders, I am more likely to overlook a 200 dollar Chameleon, with a newer breeder or less premium blood lines, than someone charging Kammer prices. If the Cham is WC price, then WC issues should be expected.
If your panther is listed for 350+ you damn well better be giving me a Perfect Healthy Animal.
When Underground Reptiles is attacked (and it is alot) I defend them. Only when the case of Attack is a WC. If you buy a WC and it dies, and it later from parastites, that's not their fault. That's the nature of WC animals, and you should have known that going in. (They should probably add disclaimers) same goes for CH.
However once again CB animals, are a completely different thing. Your CB animals should not have Parasites, your WCs should have been QTed and Treated long before having babies.
Also yes there is lots of Snakes imported, and parasites have wiped out entire collections.
