They're fun, interesting, colorful and fascinating creatures. They're also solitary creatures that are prefectly happy spending most of their time hiding. They are very easy to care for once you develope the knack for it. Keeping one or two snakes is so ridiculously simple that I wouldn't find it as much fun. I'd end up spending so much time puttering around in their cages that I'd just be bothering them. I mean really, after feeding watering and cleaning once a week what else is there to do? When you've got a whole bunch of snake however, you've always got something that needs to be done. It's a good way to keep busy.

As far as venomous snakes, I don't know anybody who does it to milk the venom. That's kind of a ridiculous notion. Venom extraction has to be done in very sterile labratory like conditions or it's worthless. That's not a hobby, that's a job. People keep venomous snakes because they like them respect them and enjoy them. If you have good training in handling venomous snakes and follow very strict safety protocols it's no more dangerous then many other hobbies. I mean really, you might as well ask why people enjoy mountain climbing skydiving or racing motocross. Why does anybody do ANYTHING as a hobby? Because they ENJOY it, that's why...
