No, not a vet, but have worked as an animal health tech for a vet. I have been keeping snakes most of my life. Venomous when I was younger, but mostly non-venomous. My wife and I bred emerald tree boas from 2000 to 2008, both the northern and Amazon basin (originally imported from Brasil before exportation was closed) sub species. Large constrictors have been banned from keeping, breeding and selling in Florida, including large pythons and green anacondas. There is a problem in our Everglades with breeding populations of Burmese and African rock pythons, which was created when Hurricane Andrew destroyed several importer's facilities in '92. They don't talk about the non-native venomous species that escaped as well. Responsible keepers had nothing to do with this problem.
A friend of ours keeps Black headed Bushmasters, The largest pit-viper in the world. These also originated in Brasil.
