Iguanas. Nice big lizards who aren't natural meat eaters. I'm a full blooded carnivore, personally - but I prefer that my reptiles be vegetarians. Less likely to try biting you once they reach 6' sizes. Most people don't want huge iguanas, but frankly I'm looking forward to Thor reaching his full adult size. In short, I want my own pet dinosaur, and the best way to get one is to raise it.
