Begining to realize that's probably what happened, he may be staying, neighbor just volunteered a roll of chain link and help, pretty sure he could stay outside a lot of the year, front porch is screened, just need a winter inside spot. Might look good walking down the street with a set of 3 foot wings attached to a harnessHonestly, someone probably let him go. People buy iguanas when they are babies and they can put them in a 25 gallon aquarium. Then they get 4'-6' long and realized they fucked up and end up letting them loose. That's why Florida is infested with green iguanas. They don't really make very good pets for most people either.
