In Panama there are release spots for iguanas in particular so long as you go through the proper contacts and a veterinarian signs off their health sheets. Luckily for us, our organization has those. There is euthanasia here. But I'm siding with your optimism. As far as the claws, only one or two are missing from each foot (only the claws, the toes are still fine). The other claws seem undamaged.
