I believe its the alfalfa in it. It should be the main ingredient in both rabbit and g-pig pellets, so I don't see why you couldn't use it. Hmm, there aws some sort of huge controversy about alfalfa pellets and sprouts at Melissa Kaplan's site that I was reading several months ago. Apparenty, one of them is bad for igs or something, but I really don't remember the details. You may want to go to
http://www.anapsid.org and find out. I also know that a lot of the stuff on that site is pretty old, so things may have changed. I'm really no expert on iguana nutrition
