listing it as a nusiance animal (like the yote or ferral cats or pigs) allows open season at any time. This should be done. In addition, I agree with taxing the crap out of the "pet market" or regulating them to the point that it does not make sense to try and sell these types of animals. I also think they should allow people during key months/times to go into ENP and get them. Guys log in, go hunt them. Keep the public in certain sectors, hunters in the other.
side note, did any of you know that iguanas are one of the most highly allergic causing animals in the world? if your asthmatic and have one, you should be really careful or plain just get rid of that animal.
