I've owned my fair share of iguanas over the years.. I guess I like getting bitten out of the relationship.. Ok just joking about that but bites do happen and they have a lot of medical problems that typically result in bad ownership.. So if you write some essay or article is would not exclude that info... Pet stores sell to people who no idea what they are getting into.
They are more of a hobby than anything to me.
I've become a bit of a fan of uromastyx. Beautiful colors, docile and they make incredible display pets.
