http://www.anapsid.org/iguana/femoralpores.html Thanks guys n gals but she is a she. her femoral pores look nothing like a males. (few) but you are all correct on her colours. she is unusual as she does go really orange sometimes, then other times the lightest turqouise

but from those diagrams and pics shes female.
so the behaviour is still odd lol. shes a mystery. jowls of a male with colours of a male at times but then she has female pores and is much smaller than an average 8yr male. oh and yes she can feed like a pig lol.
so besides this quandry, any other ideas about her pooping etc as above. Thanks.
