I find iguanas to be great pets but that is because I lucked out with a very tame docile adult female. If they are tamed right and soicalized they can be just like any other aniaml you have to care for. My iguana is "potty" trained meaning she goes in the bathroom to go potty right behind the toilet on the news paper. She goes through 2 bunches of greens a week meaning 2 of collard and 1-2 of mustard when she wants to eat. Ohter times she decides shes not eating that day and so not as much. There is a big commintment into getting an iguana with food and care. Tail whips are more common then biting since that i there first line of defense and boy does that hurt. They will and do bite when they feel they have to though.
