How is the possibility of disease addressed at expos? It would be up to each person contributing to be aware of the health of their animals. Honestly, any time you purchase an animal from a show, there's a risk of something terrible happening. Every time you vend at a show, there's a risk of something terrible happening. This is why I personally won't buy at a show, even seeing some incredible deals, unless I see something truly exceptional. So for those who would use the possibility of disease as an excuse against this sort of exhibition, it doesn't really hold much water. I really don't have much opinion either way, if people want to do something like this, let them have at it...if not, fine.
