I'm confused. Did you or didn't you take him? A vet put neosporin (a human 'medication') on your iguana? For a broken toe? This sounds fishy, because I don't know a single vet who wouldn't use an animal specific cream for an animal, and I don't see a reason why they would just put an antibiotic cream on a break. I think you're just trying to avoid flaming, and the poor iggy never went to the vet at all, but hey, that's just my educated guess.
