Yeah I guess I did over-react but Mites are such a fear of mine.
It made me mad that so called professionals/mentors would bring an animal for a meet and greet with mites - that just blows my mind. The other snakes they had with them either had stuck shed all over them and stuck eyecaps - needless to say I was not impressed with their husbandry skills and won't be attending another of their events.
Thanks for the response LGray.
