I once saw a TV show on people in Florida taking advantage of an unusual cold snap and using it to capture iguanas that people had released and are now an invasive species in parts of Florida. I wish there was a way of legislating common sense, but that doesn't seem to be the case. If only we could make everyone adopting or even buying a pet take a class - yes this tiny little iguana is really cute, and can fit in the palm of your hand, but it will grow, sometimes to 6 feet long, and live a long time! Are you prepared to house and feed a six-foot-long lizard ten years from now? No? then buy your kid a plastic dinosaur, and leave the live animal for someone who IS prepared.
