Most of the zoos or zoo type establishments I have seen have what looks to me like poorly cared for animals. I've seen incredibly skinny animals, ones with stuck shed (not just a little but entire body length), swollen mucusy mouths and noses rubbed raw. But like you said; I don't know what it takes to run a zoo or exhibition like that. I'm not being sarcastic. I realize that there's a conflict of interest there. But I feel that the animals' well being should be the FIRST thing on the people that run those establishments minds. In a perfect world the animals' care would trump the desire to put them on display. Maybe cycling animals out of the display to give them time to recoup from the stress would help as well as having a staff that cares about herps.
