I have read about this product but have never used it.
We always vet check our animals that come in, wether they be bought from the best breeders or rescued from the most horrible places, we always get a fecal exam done, so I don't think we would use this product, as we need to vet check them anyhow, I think it is safer to just see the vet. As long as you have a good herp vet. I know sometimes that is not easy
