As far as venomous, there should be some laws in regard to keeping them, but the responsible owners often do a better job than zoos at keeping the public safe from their snakes.. Zoos have escapes all the time, and possibly private collectors do as well and we just don't hear about it. Here's the difference: Zoos have people in their buildings every day, if one escaped it could easily bite someone if it felt like it. On the other hand, private collectors usually don't invite the general public in to see the snakes, and unless one escapes and gets out of the building (Which, again, could happen at a zoo just as easily if not easier..) the public is highly unlikely to be under any threat. Also, you act like zoos are completely invulnerable to natural disasters.. Wrong, they are just as susceptible to them as anyone else, sometimes even more so.Sucks that this situation happened but with the history of neglect and the authorities really doing nothing about it, I think the blame lies everywhere from where the dude got his animals from to the town that knew about the situation and did not enforce or remove the animals before this happened to the sick individual and the mental health field that is failing a lot of mental ill people everywhere.
I would personally would re-examine the industry and go through it throughly where the problem areas are at and address them instead of banning it outright. To keep peoples jobs to start with.
I personally don't think its appropriate for anybody to be keeping venomous snakes as they have no business risking the public due to the act of god such as hurricanes/tornados they cannot guarantee the animal will be still kept in the cages etc. The only appropriate places are at the zoos for public or for collecting venom to save lives otherwise to keep them as pets is really dumb thing to do when there are so many snakes out there thats not going to harm the public with their venom or large snakes
Look at what happening to florida right now with exotics threatening the public, no thanks to idiots who bred them and sold them to the wrong persons. The breeder is equally as responsible as the stupid owner. Same goes for huge felines such as tigers. Who bred them should have been held accountable.
Also, any responsible venomous keeper (Which is a fair amount of them, the media just doesn't show that side of it.) knows that venomous snakes are not pets, they are biological specimens. Private collectors keep them for the love of observing and understanding these beautiful creatures, while zoos keep them because they can get people to pay money to see them.
All in all, if either zoos or private collectors is the more responsible keeper.... The quick answer is that a lot of the time it's the private collectors.
